NFT Hydroponic Grow Systems for Agriculture greenhouse
1. Description
Hydroponics a method of growing plants without soil by instead using mineral nutrient solutions in a water solvent. Terrestrial plants may be grown with only their roots exposed to the nutritious liquid, or the roots may be physically supported by an inert medium such as perlite or gravel.
The nutrients used in hydroponic systems can come from an array of different sources, including (but not limited to) from fish excrement, duck manure, or purchased chemical fertilisers.
Plants commonly grown hydroponically include tomatoes, peppers, cucumbers, lettuces
2. Techniques
1) Static solution culture
In static solution culture, plants are grown in containers of nutrient solution, such as glass Mason jars (typically, in-home applications), plastic buckets, tubs, or tanks.
2) Continuous-flow solution culture - The nutrient film technique (NFT)
In continuous-flow solution culture, the nutrient solution constantly flows past the roots. It is much easier to automate than the static solution culture because sampling and adjustments to the temperature and nutrient concentrations can be made in a large storage tank that has potential to serve thousands of plants.
The main advantage of the NFT system over other forms of hydroponics is that the plant roots are exposed to adequate supplies of water, oxygen, and nutrients.
3) Aeroponics
The method requires no substrate and entails growing plants with their roots suspended in a deep air or growth chamber with the roots periodically wetted with a fine mist of atomized nutrients. Excellent aeration is the main advantage of aeroponics.
4)Deep water culture
The solution is oxygen saturated by an air pump combined with porous stones. With this method, the plants grow much faster because of the high amount of oxygen that the roots receive.
3. Planting pattern

The trough type floating cultivation
Leafy vegetables
