Hey Dubi
I think you are the one who knows Anwser:
Can i finish a pure equatorial Plant easyer if i start them like very early in January , February indoors? Can i shift the Harvest Date to the earlyer?? Wanna grow Thai at 45North
I'm not Dubi, but I can easily answer since I live in those latitudes: it depends on where you live, on the microclimate, by sowing in May I brought tropical varieties such as Honduras and green haze x thai to the end of flowering without too many problems, purple haze x thai and oldtimer haze were more difficult as they were harvested in early January ...
However, I am aware that it is thanks to my particular microclimate that the most difficult month here is November due to rain and above all fogs combined with the first frosts, a few km further east or west and everything changes ....
