Jef79answered grow question 5 years ago Hello.. Hope you are well..thats a real shame.. Ur girls look nice and healthy!.. Ive never heard of giving plants a stretched nite period to force flowers or anything tbh.. Personally i wudnt try this technique again as this may have bin the cause of the stress n why she hermed?? .. Just keep ur eyes on her and try to pick off as many male pods as u can see.. If numbers are low u can get away with low chances of finding seeds in ur grinder.. If she/he starts to produce alot of them then i wud say to cut him out completely and let ur other plant benefit from space n sole use of lite.. U dont want both plants full of seed n no buds of weed.. Check her 2-3times a day if possible.. Stay safe n gud luck with your garden.. 👍🍀
