@biggreens420, Yes it is a nft setup but I am sure it is a type of hydroponic system, wasn't a setting for it unless it falls under soiless. No I haven't been covering the roots or the rockwool so quite abit of algae has formed onto them, might try that black bin bag method that Athos was talking about xD since I did lose the correx sheet, don't really know how to keep the water cool thoughout the system either but I will do some research on it :).
