Just showing my NFT multi channel grows.
I started with Hydro NFT in 93. I enjoy this style best as its fast, clean and i dont have to carry sacks of coco in/out.
I use rockwool the 1.5" cubes to root and transfer to 4" blocks then on the the channels, once well rooted in the blocks.
PH is very important i stay between 5.5 to 6.0. nutrients wise i use any from H+G hydro or ionic or vitalink hydro max all work well.
I add silicon and h2o2 also regen a root by cx nutrients.
