i started the seeds in 1inch rockwool which seemed like a good idea getting them started but then i realized i was putting them into vitrually nothing the grow rocks dont hold anything while the rockwool soaks up water, at the top of each plant is a 1 inch surounding of rockwool but i didnt think it was enough to rot the roots cuase its only an inch of the root but then again its also the very top of the roots, maybe ill put the dripped off to the side.
