In the North Bay. The few growers I know have an unwritten rule of "harvest by Halloween". Some varieties I've been able to harvest Sept. 30 and those were for the effect, slightly early. The fog begins in Oct., even without the worry of rain. I'm running an early finisher to try to escape the bud rot for an experiment (Texada Skunk from PeakSeedsBC). I've tried to grow (nearly) pure sativas (Reeferman) and gone to Dec. with them and they would not finish. The ground gets too cold. I'm gravitating toward Canadian varieties. I have TGA Jack's Cleaner 2, Mosca's Old Time Indiana Bubblegum, Serious C-99 as well. The Texada is the strongest of the strains so far, this year, very pleased. Most strains are harvested around the middle of Oct.
