Jordan Gartenhaus

is one of those people that always tries to figure out how or why things work the way they do. To that end he earned a BS in mechanical engineering, but shortly after graduating he realized his time spent in school created more questions about everything around him than answers.

In an effort to prevent from overwhelming him-

self now he focuses just on making gardens as fruitful as is scientifically possible. He spends a lot of his time optimizing grow spaces to make the most of the resources available, and also strongly advocates quality automation systems. He would since he co-owns a company that designs and sells their own automation equipment, but despite the conflict of interest he actually does provide excellent insight into the “how” and “why” of gardening.

From the EditorWelcome back again, friends.

This Edition, it being our VIIth, we look to find some balance between nature and science. Often, we may perceive the two to be removed from one another yet factually, we may find they are really one and the same.

Perhaps its more of a matter of the way we have de-veloped or conditioned our brains to pick up and translate the “raw data” from the world around us, understand, store and ultimately relay and apply that data.

It's hard to say how the human brain works, and there are sure a lot of them out there; seemingly very dif-ferent yet with so many commonalities. This makes it especially curious and sometimes even amusing how an individual or a group can argue tooth and nail over a point-yet not realize they are talking about the ex-act same thing; just from completely different per-spectives. Yet either side may adamantly proclaim to be “correct” and the other “not”.

“So what's this got to do with anything hydroponic?” is what some of you may be asking. Well, quite a lot really.

It seems somewhere along the way, people drew a line between “science” and “faith”. Science is simply a way of framing things where it is believed that tan-gible proof of a “law” can support it. Faith simply says, “it's like that-and you'll have to make your own evidence if you need it”.

Yet, in the case of Science, major fundamental “laws” get completely blown out of the water every so of-ten, dispelling the “proof” of certain phenomenon or behaviors-while still not making them any less true. The difference is now there is a new “law” as to the why. Turns out it was just “faith” all along.

Now on the other hand, when people put all of their energy into “faith” and completely ignore Science, there is a good bet they are heading for some kind of disaster big or small just as quickly and surely.

Science is a discipline. In real science it's not a mat-ter of what is convenient, quick or easy: it's about fol-lowing and documenting every possible detail along every necessary step that needs to be taken to reach the out-come. It's also about removing emotion from that outcome and simply stating the results-favorable or not.

So it seems to achieve balanced critical thinking we need to sip from both the cup of Science and that of Faith.

In this Edition, we offer a feature called “How Hydro Lost It's Science”. Its a factual look back on histori-cal events that saw a young hydroponics industry transform from commercial and scientific applications to a stronger segment geared home growing enthusiests.

Would it be fair to say hydroponics has gotten “dumbed down” over the years in order to make it attractive to a broader audience?

Possibly. But on the flip side, you sometimes get people who don't want to see things become so widespread-kind of a “scarcity” mentality-it keeps the value high because the supply is low.

I would say people take advantage of the fact that there is less formal science evident in our industry now, more than ever before-astonishingly while the hydroponics in-dustry has grown to record global numbers.

Few companies divulge credible studies with regards to their products performance, in fact, we now have less showing on our labels than ever before...in spite of the fact that hydroponics fertilizers and supplements now have a wider spectrum of ingredients and benefits than they ever have.

This ridiculous phenomenon is in part the result of bad North American fertilizer labelling policies, but let's talk about that another day.

The point here is that even the products you select, pur-chase and use to grow your garden are very much based on Faith rather than Science. Seriously, think about it.

So, maybe the next time someone in-terjects some Faith based knowl-edge into a growing discussion, you might be wise not to brush it off so quickly. If you really want to think critical, turn the scope and point it back in your own direction and weigh-in on where your information comes from in making your hydroponics deci-sions based on what you perceive to be “Science”. You may find you have had Faith all along!

AThe quick answer is like this:Per YEAR you have more yield poten-tial in hydro, if you keep similar plant counts. If you bump up your plant counts to SOG (Sea Of Green) style numbers, you have the poten-tial to yield more per CROP, as well as per year.

While soil crops may be slower grow-ing, especially during vegetative growth, the harder growth that is produced can have more dry weight, while fresh weights may be similar in comparing soil to hydro home-grown. So in part, the answer also depends on what parts of the plant you are using and how they will be processed or handled post crop.To explain how you can harvest more per year with hydro, while not changing plant counts, the differ-ence comes with taking advantage of accelerated rates of growth that reduce the time it takes plants to

get to their desired size, as well as the level of control that is af-forded to the grower and how quickly they can make changes to nutrient balances and uptake. Factoring turn-around time between crops is also another plus for hydro: scrub and sterilize the system and it's ready to plant again.

When you combine the cropping time reduced in these areas, and work on losing even more time per cycle, you can effectively add a cropping cycle onto a calendar year. If you can shave two or three weeks from your vegetative growth phase and a week or more in your flowering phase each cycle...well, do the math. This gain spread out over several crops im-pacts what you can cut down from the same space every 365 days in a posi-tive way.Shifting gears again, if you aren't concerned with increasing your plant count to whatever numbers are most productive for the space you grow in relative to the variety and your growing style, you may also be able to yield more per cycle, even at ac-celerated harvest rates by carpeting beneath your lighting with an army of short and productive plants.

SOG style plantings pack in the space with solid and productive growth. Densities of one plant ev-ery four inches, while extreme, can be incredibly productive. Natu-rally this depends on how you set up and manage the garden-but in the end, insanely heavy harvests can be achieved in even less time when plants are triggered to flower af-ter gaining a few sets of leaves in veg and being forced to flower right away. Good pruning pays here, btw. The type of system you select and how well it's suited to your style and plant varieties is going to play a big role in your potential level of success. There are proven crop-ping systems with the equipment list to match available to help you stack the cards in your favor, but ulti-mately it's going to come down to you: are you willing and able to find the time and financial resourc-es to make the switch-and can you afford a set back or two while you perfect your hydroponic garden? If you can, there are rewards to be had.

Cheers, Erik [email protected]

Life is alive. Sounds obvious right, but what is it that makes it alive?

This isn’t a riddle, this is serious stuff. All witchraft and woo woo aside, surely there is more to life than what is physically here. Of course this isn’t news to most, but rarely do we apply this knowledge in the garden in any sort of practical way. We live in an age of materialism, where the con-cept and relevance of subtle energies and life force are mocked in the face of the mighty sci-entific method, fertilizers and toxic rescue chemistry. It’s a difficult subject. We are not collective-ly comfortable with the idea of energy or vibra-tion being so influential on plants and living systems. We are much more content believing that life is static and comprised of only what is physical, replicable and can be measured. But we all know that life doesn’t work like that. The further you look the less you know. The more you aim to prove the more backed into a corner you become.Life is a conundrum for sure, and one that can-not be answered by normal “science” that comes from text books. The hopeless skeptic will throw the baby out with the bath water here, but those of genuine curiosity will recognize that some of the great minds of the past did not spend their lives researching these concepts for nothing. Viktor Schauberger was known as the “Water Wiz-ard” and championed the concept of implosive energy. He made many inventions that capitalized on the regenerative forces of implosion, most of which are unknown to the public.Rudolf Steiner was a spiritual scientist that created the BioDynamic method of agriculture in

1924 when he delivered a series of lectures over eight days that represented the very first reac-tion to chemical farming now known as The Agri-culture Course. Wilhelm Reich discovered the bion and Nikola Tesla the secrets of free energy. The list goes on. We have developed a means of communicating these concepts from a platform we call BioEnergetic agriculture. The concept is that living systems retain a physical, mineral, biological and en-ergetic component. Not addressing all of them means that the potential of the system is not being maximized. Conventional agriculture is physical and min-eral’you plow and you fertilize. Organic agricul-ture begins to incorporate the biological com-ponent. But both methods of growing completely ignore the energetic element of life. BioDynamic agriculture is a method that works strictly with energetics, but mostly ignores the other aspects of growing like mineral balance and biological diversity. Think of it this way, conventional growing is drowning, organics is treading water and BioEnergetic growing is swim-ming where you want to go. The subtle energies that act as the glue to our physical reality are taken for granted mostly because we cannot see them; but they exist, in the same way that stars exist in the sky on a sunny day. They can be measured through tech-niques such as dowsing, chromatography or kir-lian photography, but these techniques are not accepted by scientific method science. But they can certainly be enjoyed in the garden. The realm of subtle energies is the new frontier of farming and gardening. The concepts of vor-texing, resonance, implosion, homeopathy, poten-tization, vibration and frequency will make more

sense once they are experienced. And once you have experienced them there is no going back. Viktor Schauberger provides some insight into the conundrum when he observed that we spend so much time thinking about how an apple fell and hit Newton on his head when he first considered gravity, but relatively no time considering how the apple got up there in the first place. The real question is not who is right or wrong, but what are we missing by having small minds. These concepts are relevant and will help you grow the best garden of your life, but you will not find the answers of why they work in conven-tional ways. It takes faith, experimentation and most of all listening to your plants. I have experienced the results of energized wa-ter, BioDynamic preps effecting an acre of land with a tablespoon of physical material, seeing crops jump 4’ overnight using a field spray. But I didn’t believe any of it either before I tested it for myself.The point is that if you apply the static scien-tific method to a dynamic reality you are always going to end up using the “science” to undermine the value of the wholistic system and telling yourself you are right. Think about it.

A GROWING FUTURE




The real question is not who is right or wrong, but what are we missing by having small minds. These concepts are relevant and will help you grow the best garden of your life, but you will not find the answers of why they work in con-ventional ways. It takes faith, experimentation and most of all listen-ing to your plants.

I have experienced the results of energized water, BioDynamic preps ef-fecting an acre of land with a tablespoon of physical material, seeing crops jump 4 inches overnight using a field spray. But I didn’t believe any of it either before I tested it for myself.

The point is that if you apply the static scientific method to a dy-namic reality you are always going to end up using the “science” to un-dermine the value of the holistic system and telling yourself you are right. Think about it.

CHOICES

If you read Part 1 in my Grozine series, The Good, The Bad, and the Ugly, you probably remember seeing Choices as being one of the “good” things I highlight. And in the general scheme of cus-tomer satisfaction, they are’ until the choices become overwhelming or excessive. And in many segments of the hydropon-ic industry, they have. EB Note-So true, talk to any newb who first flips through a commer-cial hydro Ad rag, and they will have less of an idea of what they want or need versus before they looked. What are we of-fering people: SOLUTIONS not confusion!

A prime example is HID lighting. An in-door gardening novice is forced to make a choice between dozens of different wattages and types of ballasts, scores of reflectors,

and then hundreds of lamps and only after wading through all of these options, will they have a working product. I'm not trying to pick on any one seg-ment of the hydroponic

industry, but there are many product areas that seem to have an over-whelming number of of-ferings relative to the number of actual con-sumers in the market-place.

Controllers and timers, pH and nu-trient testers, carbon filters, inline fans, even hydroponic nutri-ents these are just a few of the lines where there can potentially be an overwhelming amount of choice for new-bies to have to make.

To illustrate this point, I'll refer to a very interest-ing study conducted in a California gourmet food store where research-ers set up a booth of jelly samples, during which they switched the num-ber of offerings between 24 flavors and six flavors ev-ery few hours and recorded the num-ber of people who would stop by and sample and/or pur-chase the product. Not surprisingly, 60 percent of the market customers were drawn to the large assortment while only 40 per-cent were drawn to the smaller num-ber of jars. What was surprising, however, was that

30 percent of the people who stopped at the booth with the smaller assort-ment actually pur-chased the jelly, while only 3 per-cent of the poten-tial customers made a purchase when the larger assortment was displayed. Re-search also shows that consumers who made a purchase from an excessive number of choices often feel a sense of buyer's remorse afterwards, feel-ing less satisfied about their initial purchase think-ing that maybe they could have done better.

Bottom line to re-tailers, offer a broad selection of products, but keep in mind the poten-tial sales lost to overwhelming the uninitiated. Pro-vide a clearly de-fined path for com-plicated product lines and be sure you have knowl-edgeable employees guiding the process for newcomers.

WEIRD PRICING

Price wars in hydro have defi-nitely lowered the cost associated with beginning an entry level indoor or hydroponic gar-den. But I really have to address the weird sug-gested retail pric-ing schemes that many manufacturers of products in the hydro niche seem to have adopted.

Many of the MSRP's I've seen lately look like they were created by someone who plays the lot-tery way too much. Why would you price a quart of nutri-ent with a MSRP of $13.15? A li-ter by a different manufacturer has an MSRP of $22.41. Another has gallons at a recommended retail of $35.87? Who comes up with these prices? EB Note-My wager is either on drunken Leprechauns or Cor-porate Stooges, lol >>>




And it's not just nutri-ents; there are oodles of hydroponic products for sale that have weird pricing.

Consumers and growers alike look at weird pric-ing with a general sense of suspicion. It doesn’t fit with what they have been accustomed to seeing price wise their entire lives. There is a rea-son most items are priced ending with a .99 or a .95. While there is very little difference in rev-enue to the retailer on an item that is marked $2.00 versus one that is marked $1.99 or $1.95, the reason this is done is that consumers gravi-tate to the initial dol-lar number, as we have been conditioned to ac-cept the .99 as the way products are naturally priced. The brain says a dollar at $1.99, versus two at $2.00.

Hydroponics manufacturers would do well to study the phenomenon of psycho-logical pricing to gain a

larger share of consumer trust and loyalty. I dare say consumers will buy more of a product that is priced at 12.95 ver-sus one that is priced at 13.15 with the minor loss on revenue for each bottle easily made up for in the increased sales of the product.

PRODUCT SAFETY

As competition has in-creased over the years, some members of the in-dustry have offered prod-ucts that would be con-sidered sketchy at best, and downright dangerous at their worst. While many of the larger manu-facturers have generally placed a high value on customer safety issues, some have cut corners over the years or brought products to market pri-or to adequate long-term testing. Many of the cheap imports and base-ment built products are not certified as safe-ly constructed by North American standards.

High-powered electrical equipment is being mar-keted without the ben-efit of UL or ETL Certi-fications; nutrients are mixed with undisclosed and potentially hazardous ingredients; pest con-trols with “proprietary ingredients” are offered without the benefit of EPA approval; it seems that some members of the industry don’t have a problem playing fast and loose with their custom-er’s safety. The fact that most garden centre trans-actions occur in cash, means notification to customers about potential safety issues or recalls is virtually impossible. Caveat emptor!

EMPLOYEE KNOWLEDGE

You would think that some-one working for a grow store or hydro shop would be able to answer some basic ques-tions about plant growth or the products they offer. Actually, one would think that the employees of a store that does nothing but sell products designed to help plants grow might know a bit more than the basics of horticulture. Sadly, in far too many circumstances, this simply isn’t the case. Customers are being provided with bad information every day by employees of stores who have a narrow view of horticulture. A recommenda-tion you get from one store may be totally at odds with advice garnered from a dif-ferent store. You don’t need to cut your light cycle back to 12 hours on to get tomatoes to bloom, an erroneous bit of employ-ee provided information I have heard countless times. It’s important for store personnel to know the dif-ference between a short-day flowering plant, a long-day flowering plant, and a day-neutral plant (the category

of which a tomato falls un-der). It’s important that they know the difference be-tween a monoeicous plant and a dioeicous plant. There’s probably nothing worse than losing an educated customer due to an employee who can’t communicate on a similar intellectual level.Unfortunately, many product recommendations aren’t based on efficacy or efficien-cies; they’re made on profit margins. Stores and their customers would be far bet-ter served if employees were provided with some ba-sic horticultural training and comprehensive product information they need to correctly guide their cus-tomers to success.Obviously, due to space limitations, this is not an all-encompassing list of the “bad” in hydroponics. These are primarily my pet peeves and strictly my per-sonal opinions. In the next instalment, however, I will address and call out some of the truly egregious examples of poor taste and stupidity in hydro, aka “the ugly”. You’ll definitely want to stay tuned!

How Hydro Lost I ts Sc ience

Did the puppy that was home hydroponic science go astray, or perhaps get lost somewhere along the way during the last couple of decades-when the home hy-droponics industry in North America has reached record levels of interest and re-lated sales?

In some ways, it certainly did. If you have been fol-lowing hydroponics in North America for the last twenty to thirty years-ok, so a lot of us didn't get into it the day we were born-you would actually be able to chart a steady decline in the amount of credible scientific data that is presented to home hydroponics enthusiasts to demonstrate the efficacy of products-i.e. living up to their claims, as demonstrat-ed by replicable and repeat-able growing tests.

If one were to chart these things, what we might see is a rise in the interest of home hydroponics and re-lated sales starting to rise in the late 90's and re-ally ramp up in and around the year 1997-while at the same time a decline in the amount of authentication and discovery by the scientif-

ic community of hydroponics formulation, growing methods and other related equipment and management techniques following an opposite line.Like most historical events, there are causal factors, and even an interesting sto-ry to be had. Shall we be-gin?

For people who have been in the hydroponics game a long time, you may remember the HSA-the Hydroponic So-ciety of America. For newer entrants, the HSA basically began as a formal society of scientists and academia that had a strong tooth for hy-droponics as an applied sci-ence in horticulture, agri-culture and to some extent home hydroponics applica-tions.

Looking back, the HSA (which still exists in some form today at: http://www.lisa-rein.com/hydroponics/) was initially comprised of re-searchers, and the Society, based on membership fees and similar was able to pay for the publication of research papers conducted by members and others. It served oth-er areas too, and an Annual Meeting was key to creating and cultivating a collective of growing minds.

Now at the same time, over in an-other camp, we have a handful of mer-chants and entre-preneurs (that’s French for “broke”) pursuing the supply of hydroponic prod-ucts to the homes of North Americans as a viable and inter-esting way to grow your own foods and ornamentals. Ini-tially, this was done by mail order Advertisements-first a small Ad here, then a quarter page there, finally by the early 90's there were several com-panies aggressively sporting full page mail order Ads, and more hydroponics retail shops opening up their doors.A few of the folks from Camp “A” even-tually migrated over to Camp “B” and vice versa. By the early 90's, there were a significant number of members in the HSA that were from the budding young and scattered Mer-chant side of the industry. In fact, as the cross over

continued, it became the opinion of num-bers of members that relative to where the member fund-ing was coming from, there was not ad-equate Merchant rep-resentation on the HSA Board-or concern as to what may ben-efit the merchant community versus the scientific commu-nity, as related to hydro.After much rabble rousing on the part of the merchants, one chair on the HSA Board was af-forded to the Mer-chant sector-many felt this was highly unrepresentative; especially with who was footing the bill for the affairs that were growing into mini-conventions and trade shows. Some industry insiders noted that it was rare to see either of the two camps mingle after hours, while there are no-table exceptions coming from either side of the fence that was gradually increasing in height and breadth.

Finally, it all came to a head one evening in July during the annual HSA Conference in San Jose, USA in 1996.

Frustrated, a group of hydropon-ics merchants with vested interests in seeing the home sector grow and knowing it was go-ing to take a coor-dinated effort to do that, met late one afternoon in a room after voicing their frustrations to no avail earlier in the day and for times prior through the HSA.

It was agreed by the group that there was a need for them to create their own asso-ciation, one that better represented their needs in the commercial market-place to further growth. On the spot a cheque was writ-ten to help cover initial costs: the HMA-Hydroponic Mer-chants Society was born. At inception,

there was an alli-ance of somewhere between thirty and fifty retailers, manufacturers and hydroponics ser-vices providers.

The HMA Board was officially enacted on November 16th, 1997. The first HMA Annual Meeting that followed was in 1998, and while very grass roots in its nature, was akin to the “trade show” scene we now know today. These meetings were al-ways conducted as “trade only” events and the Industry as it was then was more or less shut down for a few days to reform together for a weekend at a shared location. People could relax and be themselves among their indus-try peers, unencum-bered by customers, while networking and making deci-sions that would affect future sales and whom was going to be buying from whom. >>>

http://www.lisarein.com/hydroponics


Although mostly American, the initial HMA shows had global attendance, with peo-ple coming from USA, Canada, France, Germany, South Amer-ica, New Zealand and beyond.

Scientists are rarely known to be good business people, so the HSA faded from out of the light-and with it, a lot of the Science, namely by way of published research papers that went along with the group for the hydropon-ics community we recognize today. While it turns out the growing public is re-sults driven, i.e. “show me, don't tell me” by way of word of mouth and the fact that hydroponic crops can be harvested and weighed in only months, as many times a year as you like, the indus-try continued to grow.

And grow we have. Just look at the Global Hydroponics Industry today-for better or worse, hydroponics is a household word. The tech-nology once thought never destined for home use, is accessible by just about anybody of any budget. While it still helps to have a green thumb, growing has never been easier.

Now, on the other hand the Industry is awash with all kinds of products claim-ing this that and the oth-er. Some of them live up to their promises and others’ well, not so much. Besides actually proving a claim,

presenting hydroponics in-formation in a proper sci-entific format (while making it accessible) opens up so many doors in so many ways.Hydroponics is an exciting way to get students, young and old alike, interested in Science and important things like living systems and ecology.

When people can branch off from the mainstream and ex-plore a world of research, for example featuring the products and technologies that are available to them from their gardening store, they start to learn about things like the Scientific Method, Critical and Objec-tive Thinking...along with a Healthy dose of wonderment and the incredible mysteries that nature holds.

Garish product claims and scantily clad chicks will get people's attention, but guess what: we have it-AND the world is watching.

Maybe we can do something with that, eh? We already know how to sell products, so let's pick-up from that afternoon back in 1996 and start to weave a little more scientific material back into our growing cornuco-pia. In doing so, we write our history as rooted and steeped in Science-with a healthy dose of shenanigans, naturally.

It's exciting to think that despite the fact that humans have been working with plants for over 10,000 years we still have a lot to learn.

For instance, amazingly, simple visual inspections are still the most prevalent tool people em-ploy for detecting plant stress. This, despite the fact that hu-man eyes can only detect a tiny fraction of the entire elec-tromagnetic spectrum of light. Think about that for a minute. Is it possible the plants are telling us something that we as humans can't see?

When light comes in contact with an object, some photons are absorbed and some are reflected depending on the energy of the photon and the composition of the object's surface. The color you perceive is a result of the photons that were reflected back to your eyes. So when you look at a healthy green leaf, you're seeing “green” because the red and blue light is being absorbed by the pigments within the leaf, and the green light is reflected back to you.

For example, plants don't absorb near infra-red (NIR) light par-ticularly well. When NIR light comes in contact with a leaf it will either pass right through, or it will be reflected by the spongy mesophyll cells within. Interesting to note is that the fraction of light that is re-flected by the mesophyll cells strongly correlate with a plant's general state of well-being. A healthy plant tends to have a more dense mesophyll layer and will reflect a lot of light, while a plant that isn't doing so well will have a porous meso-phyll layer that will allow a lot of light to pass through it. And as we established before, leaves look green because they're ab-sorbing the other visible wave-lengths that we can see (i.e. red and blue) and are producing chlo-rophyll. If chlorophyll produc-tion were to taper off, then the absorption of light in the red and blue regions should taper off as well. After all plants don't just store light, the electromag-netic energy is either used in-ternally, or is reflected back.

But light is made up of much more than just the mixture of the reds, greens and blues that are perceptible to humans. The other seemingly in-visible wavelengths of light seem to interact with a plant's surface in ways that we're only now beginning to understand.

If we pair this phenomenon with the notion that plants strongly reflect NIR light then we can create some powerful tools to help us spot patterns that we wouldn't otherwise be able to see.>>>

PLANTS Invisible Distress SignalsBy Jordan Gartenhaus

Not coincidentally, scientists have

developed what they call the NDVI,

or Normalized Difference Vegetation

Index. It is calculated as follows:

NDVI = (NIR-Red)/(NIR+Red)

This has historically been used to identify “live plants” from “every-thing else” in satellite images because it does so well at identifying vegeta-tion. It does this by comparing the amount of NIR light with and without the red wavelengths.

Since healthy plants very strongly reflect NIR light, and very strongly absorb red light, an NDVI value close to “1” would be a strong indicator of healthy plant life, and a value of “-1” would indicate something that isn’t a plant, or at least not one that’s liv-ing.

That’s great for satellite im-ages, but what about a home gar-den?

Step one is sourcing the requisite equipment, but fear not. The equip-ment you need in order to take NIR images is surprisingly easy to come by. In fact,

most digital cameras today can reg-ister infra-red light. The catch is that camera manufacturers also in-stall filters to block infra-red out since it doesn’t contribute anything beneficial to a final image. So you can either modify your digital camera to work, or you can just pony up and buy a real infra-red camera (they aren’t too expensive anyway). Once you have your camera you can start snapping pictures.

There are some subtleties to take note of however.

First, the simplest way to go about taking these pictures is with a single camera.

If you use two cameras then the perspective will be different between the two images, which will make cre-ating an NDVI image more challeng-ing (that isn't to say impossible,

however, Also, make sure to put your camera into “manual” mode if it is a point-and-shoot so it doesn't do funny things with the aperture or shutter speed during each shot.

Once you're ready, you need to take two pictures to create your NDVI im-age.

One picture should just be infra-red, and the other picture should be all visible wavelengths. If you're good with digital image manipulation soft-ware then you can add, subtract, and divide the images in order to create your NDVI image.

If you're not so well versed with Photoshop and the like, there are online tools and walk-throughs avail-able to help you get started.

Now it’s time to build your database.

Just taking a series of these im-ages isn’t going to tell you much. The value of these images is in comparing them to known examples of healthy, and unhealthy vegetation.

If you snap a picture of your crop every day and take a note about what the plants were up to you’ll notice a correlation with plant health and the NDVI. That’s because NDVI is tied so closely with photosynthetic activ-ity.

If you take this one more step, then the tools become really powerful.

Just looking at a NDVI image can be a useful in comparing the health of a current crop to previous ones, but trends are hard to see with the naked eye.

So brilliant people have developed software that will analyze NDVI images and provide a “score” based on how much photosynthetic activity is present.

From this, you can chart the score over time and watch it rise and fall.

As before, you will start to see a pat-tern emerge as the NDVI values vary naturally as the plant matures. But you will also undoubtedly see trends emerge when the plants encounter what they perceive to be stressful conditions.

You’ll notice a sharp drop in photosyn-thetic activity, and if it’s unexpected then there’s a strong possibility that your crop’s in trouble.

Although this technology is far from mature, it’s also arguably underutilized.

The cost of equipment required to generate a real NDVI plot is reasonable, and the software required in order to analyze the NDVI images is available with a Google search.

The only real hurdle in utiliz-ing this technology is in build-ing your own database of NDVI images.

But, if your crops are consis-tent and you don’t mind tinker-ing a bit then this could be an incredibly powerful tool for your tool box.

DELUXE COMPOST TEA SWIRLLING

Hello folks and welcome to lbs. journal and

another dope edition of Grozine.

Today's article is special for all you gardeners out

there needing help with developing roots and better

utilizing organics into their feeding regime. This ar-

ticle also ties into my last articles on “Bottle Rock-

et varieties” and the “Short Squats”. My article today

is on Compost Tea.

I wanted to drop a couple recipes that have been used

with high success over the years and are easy on the

growers pocket. So let's cut to it, I'm not a micro-

biologist by any means so I'm not going to go into

details about what exactly a compost tea is composed

of. If you are interested in the subject, take the

time and do your research. A Compost Tea in simplistic

terms is a beneficial microbe soup for your plants.

There are multiple benefits and purposes for incor-

porating compost teas into the feeding regime and the

results are astonishing.

There are so many compost tea recipes out there that

people have developed in their time of being a gar-

dener. Some recipes are better than others. Especially

when the person has a grasp on the general subject

and is able to add certain elements that will enhance

and affect that specific stage in growth the plant

is going through. I've always been under the impres-

sion that the plant is the Boss. It will let you know

if your tea is beneficial or not. If your plants look

like they're praying to your lights your on the right

track.

Today I wanted to drop a rooting/Veg recipe; a tran-

sition recipe; and finally a flower bloom recipe.

There are many brewers available for brewing tea on

the market today so feel free to use your brewers if

you have one already.

If not, then all you need are the products listed be-

low. General rule of thumb is to put all solid and dry

materials in cheese cloth or filtration bag and all

liquid directly into RO water.

Featuring Casey Jones FraserHydro-ScriptsPreface -- So a customer I haven’t seen in

a couple of years comes in-turns out he was on a hiatus from indoor growing. He said he wanted to go back inside after problems with his outdoor tomato crop-cold temps and heavy rains were murder on the roots. He said he wanted to shoot the works indoors-no more tak-ing chances outdoors Here's what happened when he decided to take my advice:

Customer: Yeah, I was on hiatus from indoor gardening. But this summer’s outdoor tomato crop was a bust. We had too much rain and cold night time temps in the early part of summer. I ended up with root rot and other disease problems. I’m here to get lights, fans, filters, containers... Everything!

CJF: That's too bad about the outdoor crop, but your indoor grow op won’t have rain or cold temps; that’s for sure. Do you need seed starting supplies?

Customer: No, but that’s the other thing I need to discuss. I got nearly a hundred cuttings from my buddy. He had some premi-um genetics, but he also had spider mites. The clones all have roots now, but when I removed the domes from my trays, mites were all over the leaves.

CJF: So all of these plants have spider mites, but you only have rooted cuttings? No large plants?

Customer: Exactly. So what’s the best way to spray these little plants for mites? CJF: The best way may be a dip, not a spray. Make a solution of bug spray in a wide-

mouth quart mason jar. After your cuttings have been watered with a mild nutrient solu-tion, dip them. Take each plant, one at a time, and dunk the leaves and stems completely into the jar.

Customer: Nice! That will get total coverage! I need to trans-plant them and move them into the vegetative cycle. Will this dip method affect the timing? CJF: Not by much. Whichever pest product you use, mix it at the mild dosage rate. Some

bug killers will slow plant growth slightly, but the goal is eradicating the mites. Get setup to transplant, and dip each one just before transplanting into the new containers. Wait for the leaves to dry before putting the plants under lights. After a couple of days, they should begin growing like normal.

Customer: That sounds easy enough. Will all the mites be dead?CJF: I hope so, but I doubt you’re that lucky. Spider mites are persistent, so spray with the same product 3-5 days later. Continue treatments for two weeks.

CJF: Just make sure the plants have been watered re-cently. Dry plants will absorb too much bug spray in the dip. This absorption can burn leaves, and cause seri-ous damage. If you can totally knock out all pests now, you will stay bug free all winter long. So once you kill off these mites, don’t get any more cuttings from your friend!

So a guy walks into a

Hydro Store...

Customer: Cool, I can do that. I expected to spray for at least two weeks anyway. Do you have any other advice on dip-ping?

the straight dopeHydro Product Reviews

rock absorbAlightWe are always aprehensive about applying foliar sprays. A misapplication and you can fry all of the foliage off your favorite plants overnight. Growers can also run into problems from, sun scorch or mil-dews resulting from bad foliar applications.

So when we read the label and were told “to spray “for at least four hours before the lights go out” we were all like-whoa, what? Is that right?

So we did. Next day? All good-great actually!

Plants in early bloom had darkened up and grew an extra inch over the usual. Then we did it again a few days later-even better! OK, so we can tell you 100%, follow this and you will see these kinds of re-sults while avoiding the usual potential problems

What: Add 50ml to 950 ml water-no need to worry about pH and spray with lights ON. Plants can pro-cess light reactions more quickly and are supplied with minerals and bio-active ingredients.

GZ Rated: We like. Firstly, because it takes the worry out of spraying the crop and secondly, be-cause we feel good about the application when we see our plants respond favorably every time (ap-plied every few days from veg to mid bloom, then stop) Good value-you don’t need much product to make a difference; sprays can be efficient this way.

green pad JRWe had tested The Green Pad Jr during the germina-tion process with a variety of plant types, includ-ing vegetables, ornamentals, etc. a while back

Overall, the results were favorable. It was an easy and inexpensive way to keep a steady supply of CO2 (carbon dioxide) avaialble to emerging plants.

However, a lot of growers are seeing their biggest bang with the JRs when it comes to producing cut-tings. Cuttings are very stressed. Think about it-they are limbs chopped from parent plants that

shift gears to root and become new plants for fu-ture crops. The higher levels of co2 seem to produce more robust plant material.-which is cheap and easy to accomplish with this method.

A welcome option for growers; especially propaga-tors-ideal for when transporting too to help keep young plants vibrant.

What-Small sterile and hygenic pads that give off co2 gas at a steady rate for about 48 hours (or lon-ger). They keep well. To activate, just lightly mist with water and roll up and stick into an empty plant site under your prop dome.

GZ Rated-For propagation of cuttings, it just makes sense. And for the price, why the f*&k not?The GDP is the bigger version-we may test these out in a tent with LEDS somewhere down the line.

stealth ro 200We shouldn’t brag about having an insane water sup-ply, but we will because it highlights what we have put this 200 Gallon per Day Reverse Osmosis Water Filter through, or rather, what we have put through it.

OK, so a 190 ppm water supply and a pH of around 7.9 isn’t the worst, BUT when you have it coming out at 90 psi at times-which can be enough to ocasionally blow leaks in regular plumbing, you get a sense of what life is like for our test Stealth 200.

Now do that for...well, m,uch longer than we care to mention. Let’s say embaressingly long between filter changes and maintenance. Still delivers 0 PPM.

What-HydroLogic Systems “meat and potatoes” re-verse osmosis filtration system. intended to bring marginal water down to 0ppm helping microbial life and nutrient absorption.

GZ Rated-This one is still kicking from a few years ago-we can’t say that about a lot of gear, and this wet girl sees a lot of action. Solid gear.
