Hydroponics Introduction

Hydroponics, or we call soiless culture, different from traditional soil growing, is a new growing technique without using soil. Crops are grown in a nutrient solution or into a proper medium.

It is mainly defined into two types NFT (Nutrient Film Technique) and substrate. The biggest difference between the NFT and substrate systems is the use of a growing medium.

- NFT (Nutrient Film Technique) System
In an NFT system, the plants are grown in channels which the nutrient solution is pumped through. The plan roots are kept moist by the thin film of nutrient solution as it passes by.

NFT is idea for shorter-term plants and crops such as lettuce and some leafy vegetables.

-Substrate System
In this system, the nutrient solution is delivered to the plants through drip emitters on a timed system. The drip cycle flushes the growing medium (rockwool, coconut coire, etc), providing the plants with fresh nutrients, water and oxygen.
Substrate system is often used to grow long-term plants - such as tomato and other fruit vegetables.

Advantages of Hydroponics

- Make full use of space. Vertical hydroponics can help you to realize it

- Get higher yield through vertical hydroponics

- Save water and fertilizer. Drip irrigation is usually applied to save much water and fertilizer

- Reduce pesticide pollution, save pesticide

- Improve product quality, produce safe green vegetables

- Realize modern agriculture

8. System configuration
Ventilation System(Open the window)
The ventilation systems in our company consist of Roof Ventilation Systems and Side Ventilation Systems according to the difference of the installation position. The Roof Ventilation Systems include the Roof Track-Cross Ventilation System and Roof Row-Rack Ventilation System. The Side Ventilation System refers to the side Cooling-Pad Ventilation System. Moreover, we also supply the Roof or Side Plastic-Film Reeling Ventilation System (Manual or Electric).
Side Cooling-Pad Ventilation System
Main Accessories: gear motor, pinion for row-rack ventilation system, hollow rack, shaft-bearing plate, rack-window connector,etc.
Shading System
The Shading system can keep out redundant sunshine, preventing the plants from being burned in the greenhouse. And it can regulate the heat or reduce the cost for the operations.
Outside Shading System is fixed above the frame of greenhouse, supported by the uprights and beams. Outside shading net is made by black and round-wire materials and fastened by black polyester strings.
Cooling System
Our company is specialized at the products of cooling pads and fans, usually used cooperatively. The cooling pads are installed on one side of the greenhouse, the exhaust fans, the other. (The air-circulating fans are installed in the greenhouse.) The exhaust fans eject the air from the greenhouse (The air-circulating fans promote the circulation of the air in the greenhouse), negative pressure formed in the greenhouse. The air enters the greenhouse through the cooling pads, resulting in the effects of cooling, moistening and air-dedusting.
Cooling pads
Main Accessories: gear motor, pinion for row-rack ventilation system, hollow rack, shaft-bearing plate, rack-window connector,etc.
Heavy-Hammer Type Exhaust Fan
A) The frame, structured by thick galvanized steel sheet which is has strong anti-corrosion property, is made by the CNC bending machine, CNC shearing machine and the technology of CNC punch processing.
B) The frame has strong hardness and great toughness, which can be in service for long time.
C) The automatic belt regulator is equipped to preventing the belt from falling off, not necessary to regulate manually during the service period of belt.
D) The blades, driven by the belt through the motor, are shaped by reasonable style and angle, punched and twisted to be framed, passing the test of dynamic balance and the test of static balance, ensuring the strong blasts of air through them and the low noise that is caused.
E) The louver, made by aluminum alloy or galvanized steel, has the special switching structure, pneumatic type, ensuring itself turn on and off perfectly and functioning as the role of wind-proof, rain-proof and dust-proof.
Air-Circulating Fan
A) The motor has the great performance of rain-proof, wind-proof and dust-proof, passing the destructive test of 360 hours. It works in low noise and can be in service for long time.
The shell is designed by the principle of air collector, advanced energy-saving technology, and thermally protecting auto-system.
B) The blade is punched by the light aluminum materials, large tilting angel, great blast capacity and low noise.
C) The accessories are made by the superior thin steel sheet, light and beautiful, easy to install.
D) The blast capacity can be optimized and designed by CAD, ensuring the air circulation and uniformizing the temperature, humidity, and the concentration of CO2.
E) You can choose the different frame, made by stainless steel or painted steel.
Heating System
Heating System of Greenhouse refers to a set of suitable heating facilities chosen to meet the heating demands, consisting of heating source, heat-radiating facilities, heat-transmitting facilities. The main accessories include furnace, transmission pipeline, circulating water, radiator and sorts of controlling or regulating valves, etc.
Irrigation System
Irrigation system includes drip and spray irrigation system, working principle is that the water is extracted from the source, pressurized, filtered properly, then through the water-transmitting pipeline into the irrigation facility on the field. At last, the irrigation water is released by the irrigation emitter of the irrigation to the plants of the field in the greenhouse.
Control System
Control System of greenhouse is a kind of environmental automatic control system that is designed for the agricultural greenhouse, agriculture environmental control and weather observation, able to measure a lot of agricultural factors such as direction and speed of wind, temperature and humidity of air or soil, air pressure, rainfall, solar radiant quantity and ultraviolet intensity, etc. It can control the facilities of ventilation system, shading system, cooling system, illumination supplement, irrigation and fertilization, adjusting the inner environment of the greenhouse to the most suitable conditions.
