What is Hydroponics?
Hydroponics is the method of growing plants without soil (i.e., soil less cultivation.) In this technique the root absorbs balanced nutrient which is dissolved in the water that meets all the plant development requirements. There are many aggregates and medias which support the plant to grow.
Why grow hydroponically?
Carbon dioxide + Water = Glucose + Oxygen
6CO2 + 6H2O= C6H12O6 + 6CO2
Being one of the most sterile and effective technique to grow plants, we can get many times greater yields than the conventional method. Many pests are carried in soil, so doing without it generally gives you a more hygienic growing system with fewer problems of disease.
Vertical farming is the practice of growing crops in vertically stacked layers. It incorporates controlled-environment agriculture which aims to optimize plant growth. Vertical Farming system helps to increase their yield drastically that comes with a smaller unit area of land requirement and reduces the cost. Crops grown traditionally depend on supportive weather and suffer from extreme or unexpected weather occurrences. GFT’s vertical farming in high-tech polyhouse produces crops around the year and all seasons.
Nutrient Film Technique (NFT)
NFT consists of a long grow chamber such as PVC pipe or channel. At evenly spaced intervals along the pipe, there are holes containing either collars, baskets, or in some cases, grow media in which plants are held. The roots of the plant hang down in the hole and a shallow stream, or “film” of water is run across the root tips.
NFT relies on a continuously running pump to deliver a low but continuous flow of nutrient over the plant roots. The pump used must be designed for continuous operation.
Flatbed is the normal rectangular plot being broken up into a series of narrow beds, set between access paths. It is the most efficient water and nutrient delivery system for growing crops. It delivers water and nutrients directly to the plant’s roots zone in the right amounts, at the right time, so each plant gets exactly what it needs, when it needs it, to grow optimally.
