@tonygreen when you stress test your males, do you switch up the light cycle? I have been trying to find a keeper male, and the past two have looked great, then thrown hairs on me. Both threw exactly two hairs on one of 100 flower sites near the top of the plant. Both went through the same treatment, in flower room for a week, then quarantined to a room where i have to remember to turn the lights on, so light cycle becomes random, but never more than 12 hrs on. also the transition to prep the male flower area had each one on the dark for 2 days(while i got the new area ready) after flowering for the first week under 12/12. Then, they are fucking lucky if i can remember to feed them since they are on the other side of the house(coco near drying out completely). basically when i realize they are males, they get treated like shit. Both have similar lineage(sourdawg and underdawg D), and both threw hairs right after the 48hr dark period after flowering for a week. I guess if they were ladies and i got one or two nanners on the whole plant i wouldn't even think about tossing them, so that logic means they may still be keepers. Hope this is an ok place to ask, you have shared a lot of breeding knowledge in this thread, so i figured why not.
