?Commercial DFT Hydroponics Growing System
DFT Hydroponics Growing System belongs to one kind of nutrient solution hydroponics, by using PVC pipes to store nutrient solution for supplying plant nutrients, which is more suitable for leaf vegetable cultivation.
All pipes and pipe fittings are made by high quality PVC in food-grade, it’s very safe, non-toxic, and non-polluting, without any damage to plants.
The shelf and pipes sizes can be customized according to the actual needs.
Commercial DFT Hydroponics Growing System deep fluid flow method is the most primitive method of hydroponic system, which refers to a hydroponic technique in which the root system of the plant grows in a deeper and flowing nutrient layer. The plating tank is filled with about 5 to 10 cm and sometimes even more profound nutrient sour, placing the root system of the crop in it, while using the water pump intermittently to open the supply fluid to make the nutrient liquid circulate flow, to supplement the oxygen in the nutrient solution and make the nutrients in the nutrient solution more uniform.
This kind of cultivation of nutrient sour layer nutrient from is relatively stable, but also solves the difficulty that the nutritional liquid culture system needs power failure can not function properly.
The characteristics of DFT Hydroponics Growing System
1. Deep
Deep refers to the planting tank itself containing the nutrient solution itself is deep, and the nutrient fluid layer in the plating tank is deep.
The root system can be extended into a deeper nutrient solution, the total amount of nutrients in the whole planting system is more, the composition of the nutrient solution, concentration (including the concentration of various nutrients, total salt concentration and dissolved oxygen concentration in the nutrient solution), acidity, moisture, and temperature, etc. are not easy to produce sharp changes, the root system growth environment is relatively stable, nutrition supplement and adjustment is convenient This is a significant feature of deep fluid water training technology.
2. Flow
Refers to the nutrient fluid is circulating and is intended to:
(1)
Commercial DFT Hydroponics Growing System increase the concentration of dissolved oxygen in the nutrient solution;
(2) eliminate the "nutrient depletion area" between the root table and the extra-root nutrient liquid when the nutrient fluid is kept so that nutrition is supplied to the root table in a timely manner;
(3) To reduce harmful metabolites secreted by the root system and accumulate on the root table, such as organic acids, physiological acids and alkalineness produced by the absorption of the root system to the selection of ions, and other metabolites;
(4) To re-dissolve certain nutrients that fail due to precipitation and supply crop growth needs. 3, suspended
Suspension refers to the hanging of a plant planted on top of the surface of the nutrient fluid, with the aim of:
(1) Keep the root neck away from the liquid surface and prevent the root neck from being immersed in the nutrient solution and causing decay or even death (except for bog plants or crops with oxygen-inductive tissue from the ground to the ground);
(2) Improve the oxygen supply of the root system: part of the root system can be extended into the nutrient solution to grow, while the other root part is exposed to the nutrient liquid surface between the fixed plate or the fixed mesh frame of the part of the moist air so that the nutrient solution and the root system in the air can absorb oxygen, Adjust the fluid layer depth of the nutrient solution and the amount of space between the liquid surface and the fixed plate or the fixed mesh frame according to the crop's growth and climatic conditions to regulate the absorption of oxygen from the root system.
