Do all pot plants start flowering

when the amount of daylight drops below 14 hours a day?(auto-flowering strains not included)I live in Mich. and Aug. 13th is the date that this happens here.I have 3 sativa/indica hybrids over 6 1/2 ft. tall and covered with pre-flowers.I'm hoping to have enough time to get some decent buds.Maybe a month and a half flowering time.We're famous for our late Sept. frosts. Any info would be appreciated.Thanks

i would say it should start to flower by then.... they say u should harvest after the first frost anyways you will be fine...

yes u will have flowers on plants on the wonderful day of aug 13th my birthday!!!my birthday will birth buds,,,happy growing yoyr plant looks like it couldnt ask for anything more,healthy

i'm in the same boat with you pal. but ii'm hoping for a late frost, since we have been having a warm and humid summer

Well happy B-day in advance!.....I'm hoping for a late frost too. Hey fdd2blk...Any advise?
