i live in the 707 and they will flower when light cuts back. could be any time around september. mine are preflowering and have white hairs. so that means time is coming
same, I've got preflowers too. I ripped them allll off though carefully and none have come back. I just neeeeeed more vedge time because I don't want to have to grow this winter, but I will if I have to.
From my experiences in the same general "area", I usually have flowering underway by the last week of July/first week of August. Not set in stone, but usually.
im a little more down south but mine go till end of august and a little september at the least. sometimes even longer...
I concur. I have done careful analysis the last 2 grows (916 area code), Twice. I have very late July early August as the time when most flowers start to show. That would mean early Oct. for your '90 day wonders' or early flowering/harvest strains i.e. AK-47, J-27, Early Girl,etc. And late Oct. early Nov. for your late flowering Sativa's (Haze's, and the like). Hope it helps, and thank the good lord we don't get rain during the summer. These damn caterpillars are bad enough..Sheesh. Peace, docdj
