I have a table with a 20 plants area easily (saying 1.5'x1.5' is allowed) with a 1000w HPS light (1 blue and 1 red) I have the resivior and everything. All vented. Fanned. I have a hydro 6pack for nuitrients. I have a big bag of rockwool grow blocks. How do i use this setup ? Timed flow ? what times ? Hieghts ? Distance from light ? Better nuitrients ?
