Millions of years of natural selection has determined what the thickness of the stem should be. Due to man's artifical selection the stems and stalk of the plant may not be able to support the number and weight of the bud produced by the plant. If that happens , use artifical supports to hold 'em up.:smokin3:
k well i duno if its the ligth mayb i got two 54 watts lights and i do have a fan rotating the air but it gets kinda hot in my grow room kuz of the heat and humidty but usuyally i think its prolly upper 70's and lowers 80's
I've read that putting a fan directly on the plant to where it's literally swaying from the fan's air flow (not too violently ofcourse) it exercises the stem to make it thicker (similar to the effect of lifting weights for humans). Or maybe I was high.
