Agriculture greenhouse hydroponic growing nutrients systems

  Substrate cultivation is the largest method in soilless cultivation. It fixes crop in organic or inorganic substrate, by method of dripping or trickle irrigation, and supplies crops nutrient solution. Culture substrate can be filled into a plastic bag, or laid in the cultivation channels or grooves. Substrate culture nutrient solution is not circulating, known as opening system, which can avoid the spread of disease through the circulation of nutrient solution.

  Substrate culture has strong buffer ability, so there is no contradiction of moisture, nutrients and O2, and the equipment is more simple than hydroponics and aeroponics, even without the need of power, so less investment, low cost. This culture method is widely used in production.


Hydroponic Details

1. The soilless system is used coconut coir as substrate.

     There is nutrient solution supply machine, which can control the EC value and PH value automatically. Inside installs hanging pipe and hanging line.

2. Substrade: coconut coir

     The parameter of coconut coir: biological and environmental, plenty of organic nutrients, retaining water and ventilating.

      PH value: 5.5-6.5      EC value≤600μs/cm

3. PVC planting trough

    The planting trough is made of PVC pipe, thickness 3-4mm, the top width 180mm, bottom width 120mm and height 160mm.

    The planting trough can be put on shelves, and also can be put on the ground or under ground. The PVC trough has many sizes, customized by you.

4.Planting Arrangement

    Install 8-9 rows in the greenhouse with 12m span, evenly distributed; install 5-6 rows in the greenhouse with 8m span , evenly distributed.

    One side is a little high, and the other side is a little low for drainage of the wast nutrient solution. Install track between the two rowa for daily management and picking.

5.Irrigation and fertilization

   The irrigation system is including nutrient solution supply machine, water pipe, branch pipe and drip nozzle.

   The machine can be controlled EC value and PH value automatically. The main water pipe is PVC pipe.


The advantage of hydroponics

1. Save the land. We can plant any where , even the roof top.

2. Save the water 85 %.

3. Save the labor.

4. Save the fertilizer 80 % .

5. Save the pesticide, friendly of the environment .

6. High production.

7.Product harmony. Little waste.

8. High quality and more safety.

9. All the growing conditions can be controlled.  


Types of hydroponics systems:
In commercial production, The hydroponics systems including NFT (Nutrient Film Technique) and substrate. Them main difference is the use of a growing medium between NFT and substrate systems
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 suit to shorter-term plants and crops such as vegetables and some herbs.
Substrate System 
In this system, the nutrient solution is delivered to the plants through drip emitters on a timed system. The dripcycle flushes the growing medium . providing the plants with fresh nutrientswater and oxygen.
Substrate system is often used to grow long-term plants
