You might consider a Mimosa strain. They are fast, early finishers, also very high in THC. Had a couple last summer, went into the open roof greenhouse in mid-June and were done by mid Oct., good yield. I'm located in the SF CA. area. ,I started way too early last year. I had sprouts March 8th. They were in 7 gallon pots by mid May when I took them outdoors. They got a bit bigger than I wanted, but the weather around here really did a number on them for flower. Lost a lot to mould.
I'll be starting seeds around the end of April this year, to go outdoors mid to late May, with the girl going straight into the ground late May to June 1st just to be sure.
I start them under 15/9 since that's the daylength for this latitude at the end of May. I can almost always get to early October before frost hits, and usually to mid to late October, though that's pushing it. If my plants aren't done by Oct 15th I get worried, so it's mostly Indicas and hybrids that do well. I don't have room for a hoop house or greenhouse.
