Why choose NFT systems?
Nutrient Film Technique systems are some of the most productive available, and they are often the chosen method of commercial growing. Plants are grown in an inert medium (usually RockWool cubes) and placed into a light-tight and shallow channel. Nutrient solution is continuously circulated, flowing over the roots up to 24 hours per day. The name of this growing method was so coined in order to stress that the depth of the liquid flowing past the roots should be very shallow in order to ensure that sufficient oxygen is supplied. This growing technique is generally favored by gardeners that wish to grow multiples of small to medium sized plants that will yield heavier than their size would usually determine.
