Nutrient Film Technique (NFT) is one of the five types of hydroponic systems. Simple backyard systems or commercial crop production can be done with this system setup.
The name ‘Nutrient Film Technique’ suggests that plant roots are not completely submerged but instead the plant is inserted into a netted cup where the roots are exposed to the film of the nutrient solution. NFT involves the use of:
PVC (circular or squared) as growth channels. The size of PVC is chosen according to the type of crop being grown. 2” PCV lengths are ideal for lettuce and herbs whereas 3” PVC can be used for patchoi, kale and any larger leafy vegetable.
