Ive switched from MG because I ran out... The 3 out side are in MG and are doing fine... I already sampled bud off one and the taste and high was good. MG didn't burn my plants. But anyway I use Kellogs potting soil now with bat guano and lots of other good stuff in it. I usually mix in about 1/3 perlite now to.Ah, that was a few months ago ha. Get those CFL's closer since they don't produce much heat from the light itself, you can keep them as close as 2-3" without harming your plant and having your lights suspend horizontally gives the most luminous output for your plant which they will love you for.
