Just wondering why people still use NFT? Water and nutrient uptake are affected by DO levels at the root zone, which is controlled by various metabolic processes that are influenced by environment. NFT is one of the poorest techniques at providing sufficient DO as the accumulation of layered root masses inhibit gas exchange. I know some growers try to mitigate this issue by modifying the depth and shape of the trough, but inevitably the exit drain of the trough will have less DO than the delivery creating an imbalance within your crop. One of the best ways to promote high cannabis yields is focusing on consistency, and high yields are a function of good cannabis husbandry...and I really don't think NFT falls into that category.
