Nutrient film technique or NFT, is where a very shallow stream of water containing all the dissolved nutrients required for plant growth is recirculated past the bare roots 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.
Top Drip is considered one of the most common, and the Hydroponic setup used for this type is also known as “Bato buckets or Dutch Buckets”. While the system could be applied to grow plants in-doors, it is more frequently related with outdoor use.
This a type of NFT system to be used to grow animal or livestock fodder. This turns your dry feed into live healthy organic nutrient-rich feed. This same system can be used to grow Wheatgrass and Microgreens.
