I need to start my 2nd 4x4 tent and spread these kids out.. I am currently in gravel in planters in a 4x4 tent with 13 plants and wanting to scrog. I have them under 600 watts using ebb and flow. The gravel I bought was not the pea gravel I was promised and after a nightmare of trying to wash this crap I have become interested in the coco coir and picked up some 2'x2' x 1/2 " coco coir planter liners. I was wondering if I could lay down a couple of layers of these in my flood table in my second tent and just plop my 4" rockwool cubes and assorted roots down on top of this medium after removing them from the gravel. Yes ? no? maybe? If yes how thick would the coco need to be under the plants in the grotek table? plants are currently about 24" "long" and I have been LST ing them. Advice and thoughts are welcomed.
Peace
