Types of rock wool cube systems
In commercial production, the two primary hydroponics growing methods are NFT (Nutrient Film Technique)
and substrate. The biggest difference between the NFT and substrate systems is the use of a growing medium.
- NFT (Nutrient Film Technique) System
In an NFT system, the plants are grown in channels which the nutrient solution is pumped through.
The plan roots are kept moist by the thin film of nutrient solution as it passes by.
NFT is idea for shorter-term plants and crops such as lettuce and some herbs.
