howdy all, i've got 6 plants growing in soil under 430 hps. went from 24 to 12/12 four days ago. being a first - time grower, i THINK i've got 2 females from the looks of them(pistils)....but not 100% sure as of yet. how long do i have before i MUST get males outta there (before pollenization occurs). should i put plants (i think are males) outside to be safe?!? sure would appreciate any info.
