I dont usually have issues but once in a while I do and want to tell you about it. I was growing Dr. K Incredible Bulk under 800 watts . We had a really hot week or two where I ran the A.C through the chiller to keep their environment at 75 degrees around the clock while it was well over 105 outside. No problem, just as usual and life continued. I had no Idea that the A.C was purposely shut down just before she went to bed and turned back on again after she woke up lmfao...... Buds were massive and beautiful with not a male flower to be had... Full of Fuckin seeds thats why they were so big and firm LOL. Temp flux f'ed them up bad.... But lots and lots of female seeds wich I ran and none have hermied and mostly grew true to their predecessor. Maybe luck? Im still on the fence with this ....
