I'm not as far north as you and I grew KC33 a couple years back. Had to chop at the end of September, but could have easily gone another two weeks, maybe even three or four. It'll probably be late October for you.
Couldn't agree with you more. Was Hoping for mid October but some look really jungle sativa influenced and will stay in the ground till nature freezes us out. Freeze out can be anywhere from 1st of October to clear till December around here.
