I have just started a nice strain of pppfm,and was wondering if growing hydroponically,how long should the roots be in proportion to the plant. I know that the root is not very restricted(rockwool-pellets)but, should they be twice as long?
Recently I have purchased a three bulb system from stealthydro. I would like to know which spectrum to use in each stage of growth. The bulbs are SHO-105W-CW;
SHO 105W-WW 120V/60Hz; EIKOhg SP105/50med.. Any help would be appreciated and greatly reknowned...
