The different type of hydroponic system used

Hydroponic Systems Hydroponic systems are characterized as active or passive. An active hydroponic system actively moves the nutrient solution, usually using a pump. Passive hydroponic systems rely on the capillary action of the growing medium or a wick. The nutrient solution is absorbed by the medium or the wick and passed along to the roots. Passive systems are usually too wet and do not supply enough oxygen to the root system for optimum growth rates. Hydroponic systems can also be characterized as recovery or non-recovery. Recovery systems or recirculating systems reuse the nutrient solution. Non-recovery means just what it says. The nutrient solution is applied to the growing medium and not recovered. The Wick System The wick system is a passive non-recovery type hydroponic system. It uses no pumps and has no moving parts. The nutrients are stored in the reservoir and moved into the root system by capillary action often using a candle or lantern wick. In simpler terms, the nutrient solution travels up the wick and into the root system of the plant. Wick systems often uses sand or perlite, vermiculite mix and a growing medium. The wick system is easy and inexpensive to set-up and maintain. Although, it tends to keep the growing medium to wet, which doesn't allow for the optimum amount of oxygen in the root system. The wick system is not the most effective way to garden hydroponically. The Ebb and Flow System The Ebb and Flow hydroponic system is an active recovery type system. The Ebb and Flow uses a submersible pump in the reservoir and the plants are in the upper tray. They work on a simple flood and drain theory. The reservoir holds the nutrient solution and the pump. When the pump turns on, the nutrient solution is pumped up to the upper tray and delivered to the root system of the plants. The pump should remain on for about 20 to 30 minutes, which is called a flood cycle. Once the water has reached a set level, an overflow pipe or fitting allows the nutrient solution to drain back into the reservoir. The pump remains on for the entire flood cycle. After the flood cycle the nutrient solution slowly drains back down into the reservoir through the pump. During the flood cycle oxygen poor air is pushed out of the root system by the upward moving nutrient solution. As the nutrient solution drains back into the reservoir, oxygen rich air is pulled into the growing medium. This allows the roots ample oxygen to maximize their nutrient intake. Rockwool and grow rocks are most commonly used growing mediums in Ebb and Flow type systems. The Ebb and Flow is low maintenance, yet highly effective type of hydroponic gardening. Nutrient Film Technique The Nutrient Film Technique or NFT system is an active recovery type hydroponic system. Again, using submersible pumps and reusing nutrient solutions. The NFT uses a reservoir with a submersible pump that pumps the nutrient solution into a grow-tube where the roots suspended. The grow-tube is at a slight downward angle so the nutrient solution runs over the roots and back into the reservoir. The nutrient solution flows over the roots up to 24 hours per day. Oxygen is needed in the grow-tube so capillary matting or air stones must be used. The plants are held up by a support collar or a grow-basket and no growing medium is used. The NFT system is very effective. Although, many novice hydroponic growers find it difficult to fine tune. It can also be very unforgiving, with no growing medium to hold any moisture, any long period of interruption in the nutrient flow can cause the roots to dry out and the plants to suffer and possibly die.

Hydroponic Systems

Hydroponic systems are characterized as active or passive. An active hydroponic system actively moves the nutrient solution, usually using a pump. Passive hydroponic systems rely on the capillary action of the growing medium or a wick. The nutrient solution is absorbed by the medium or the wick

and passed along to the roots. Passive systems are usually too wet and do not supply enough oxygen to the root system for optimum growth rates.

Hydroponic systems can also be characterized as recovery or non-recovery. Recovery systems or recirculating systems reuse the nutrient solution. Non-recovery means just what it says. The nutrient solution is applied to the growing medium and not recovered.

The Wick System

The wick system is a passive non-recovery type hydroponic system. It uses no pumps and has no moving parts. The nutrients are stored in the reservoir and moved into the root system by capillary action often using a candle or lantern wick. In simpler terms, the nutrient solution travels up the wick and into the root system of the plant. Wick systems often uses sand or perlite, vermiculite mix and a

growing medium. The wick system is easy and inexpensive to set-up and maintain. Although, it tends to keep the growing medium to wet, which doesn't allow for the optimum amount of oxygen in the root system. The wick system is not the most effective way to garden hydroponically.

The Ebb and Flow System

The Ebb and Flow hydroponic system is an active recovery type system. The Ebb and Flow uses a submersible pump in the reservoir and the plants are in the upper tray. They work on a simple flood and drain theory. The reservoir holds the nutrient solution and the pump. When the pump turns on, the nutrient solution is pumped up to the upper tray and delivered to the root system of the plants. The pump should remain on for about 20 to 30 minutes, which is called a flood cycle. Once the water

has reached a set level, an overflow pipe or fitting allows the nutrient solution to drain back into the reservoir. The pump remains on for the entire flood cycle. After the flood cycle the nutrient solution slowly drains back down into the reservoir through the pump.

During the flood cycle oxygen poor air is pushed out of the root system by the upward moving nutrient solution. As the nutrient solution drains back into the reservoir, oxygen rich air is pulled into the growing medium. This allows the roots ample oxygen to maximize their nutrient intake. Rockwool and grow rocks are most commonly used growing mediums in Ebb and Flow type systems. The Ebb and Flow is low maintenance, yet highly effective type of hydroponic gardening.

Agricultural Shade Net

Plastic mesh agricultural shade net offers protective covers specifically for agricultural use to enhance

earlier, higher yields and protection against winter weather, spring freezes and pests. This kind of shade net

increases soil and air temperature during daylight hours and it slows heat loss and aids in maintaining soil

temperatures at night.

Materials: Plastic mesh.

Uses: Plastic shade net for agricultural protection can be used for frost protection, pest protection and

increased yields.

Features and benefits of using shade netting for agriculture:

Early Planting and Earlier Harvest

Improved Plant Growth and Higher Yields

Frost and Cold Weather Protection

Heavy Rain, Hail and Storm Protection

Insect, Animal and Bird Protection

Application: Plastic mesh agricultural shade net is ideal for use on crops such as sweet corn, strawberries,

spinach, celery and many more. It has also been used for new lawn seeding and to protect seed from harsh

sunlight and birds while helping retain soil moisture. It is also used in greenhouses to help retain moisture

for seeds. Plastic shade netting for agriculture is UV stabilized to promote reuse. It is easily laid manually or

mechanically. It is made to order in widths up to 50 feet. Folding is available on most products to enable

deliveries.

Sun Shade Net

Shade net is made of polyethylene (HDPE) material by adding UV stabilizers and anti-oxidants. HDPE

sunshade net has the characterisics of lightweight, high-strength, anti-aging, large-area coverage and it has

the ability to adjust control environment, optimizing climate and improve plants in the growth of adverse

climate conditions.

Sun shade net is a materials for realization of security or high-yield, high-quality agricultural cultivation

techniques. It is popularly used in vegetables, flowers, edible mushrooms, fruits, medicinal herbs

aquaculture industry, and other fields.

Page 3: Hydroponic Systems

Sunshade net systems (shade, heat retention, or blackout curtains) reduce heat loss by reducing the air

volume needed to be heated, creating an attic in the greenhouse for an insulative air barrier, and reducing

the stratification of heat energy up to the roof. During the summer months the plastic sunshade screens can

be deployed over the crop, returning temperatures back to an optimum growing range.

Sunshade net is mostly used in agriculture as ventilate shade net for greenhouse, offering the features of

light reflection and transmission , breath freely, long usage life and stable performance.
