I still have some plants flowering, but most of those I'm not expecting much of anymore. it's a cross I made myself that contains a bit too much late genetics.
still one plant(other cross) on guerilla that I do expect a decent finished harvest from though, it should be about ready now but I don't have time to visit and harvest right now, will happen in a few days though.
then everything that's left is too late, maybe I'll still harvest some from it in november or so, but depends how well they take the autumn-weather and how long they still have to go(but I'm expecting at least 3 weeks more for all of them), maybe I'll eventually harvest them prematurely if they can't take the weather anymore, and turn it all into hash. (it's a cross with a himalayan landrace though, so I expect they'll take the cold and wet autumnweather better as most plants)
ideally in my climate you would want to harvest the first half of september(or earlier, but that's only possible with auto's or a few extremely early photostrains), then you can harvest before the budrotseason really takes off. but up to october is still fine too, this year I had another cross that's also still on the late side, harvested most of it between end september and half october, but it still finished fine with little mold.
but the later you go, the more you're depending on moldresistant genetics and luck with the weather. one week of rainy autumn weather and everything can mold to shit.
