our plant is a 4 month old indica/sativa mix, (indica dominant) and is now about 1' 4" tall. We have had the lights 12 hours on 12 hours off for 8 days now and it still hasnt shown any form of sex. Is there a good chance its female or do males take this long also? BTW...in my signature its only 3 months old, its gotten a bit bigger since then.
i switch to flower right at, or before 12" or so. the larger they get in veg, the larger they'll get in flower. 4 months old tells me you have inferior lighting. hid is the way to go. with the lighting you have, you're gonna have too much plant for your light. with ;ess than optimal lighting, everything (including showing sex) is gonna take longer....
are you talking about the signature picture? it was only 3 months old in that pic, are camera is not working right now so i cant take any recent pictures. its gotten quite a bit bigger since then.
About 2 weeks to see sex, and in 4 weeks you should see some nice buds. That is if you have enough light.
