i'll probably be chastised for the following statements but, here ya go;

i start seeds/clones in bacto starter soil (has root stimulators and light starter ferts) in a quart sized pot. after 4 or 5 nodes, i transplant the plug (after 2 weeks, bacto gets hard as a brick and won't absorb, drain water effectively) into a 3 gallon pot of miracle gro garden soil supplement (not made for pots, is VERY rich for 3 weeks, it drains immediately and dries in a day). my plants show slight burn, then take off. by the time i get to flower, the time release is used up from watering everyday, and plants are the size of those twice their age in other soils.

~note~ DO NOT START SEEDS IN MG SOIL! THEY WILL DIE! as previously stated, mg is VERY rich, use only to transplant.

love, kp
