    10" Rhizocore Netpots

    Are these 10" netpots too big to only grow 1 plant per 5 gallon bucket (DWC)? Also if said pots aren't too big, will a 1.5" rockwool cube be big enough? Any help would be greatly appreciated.

    Germ method states no Rockwell - But has anyone?

    I watched the germination video again when i received my first package. It certainly states that we shouldn't use rock wool or any other starting method.
