I have 3 areas where I flower males... 2 isolation chambers and a cardboard open topped unit on top of my kitchen fridge with a 2' t5... I pinned a towel to the ceiling that drapes down and covers all but the bottom 3 inches or so so there's really no air movement at all... the pollen falls straight below the flowers or sits on tops of leaves... I like my males to get random and often light cycle interruptions to stress em to light leaks specifically... wouldnt use a male that threw hairs just from a lil light... currently I have blue moon rocks in flower in the brothel, my FloScout (gsc forum x flo) is in flower in the open cardboard rig, and I been spraying a catpiss cut in the small isolation.... next males are another sour bubble run for more pollen, an Elmers Glue x Fire Cookies... and the 3rd is in question... possibly a glue reversal... you can always keep good males cut of a cut of a cut till you're ready to flower... I got down to 3 keeper males in anticipation of finding future greatness....
