I live in South Eastern Ky, done small grows for 6 years now outdoors (about 5 plants each year) and if I start them early (within first 2 weeks of March if its warm enough) I usually harvest around the last week of September, or the first week of October. Sometimes a week or two later than that. Theres usually no way they make it to November tho. && The light cycle, the light usally begins decreasing around July 21st.
This year, I had everything perfect up until a month ago.. Had 4 unknown purp seedlings and 4 Afghans in the ground about 1.5 ft tall & really healthy looking plants. Was pumped af, until a huge hail storm hit and 2 straight weeks of rain, and it damaged every one of them. Lost 2 purps and 1 Afghan. The other 5 all lost crucial fan leaves.. and 2 even topped themselves. But it stunted all of the growth up until the last week or so, with the sun being out. Theyve grown 2 ft in the last week alone. So hopefully theyve pulled thru it without being stressed enough to turn them into males. Moral of the story being: Kentucky weather is extremely unpredictable. Try to baby your plants close to home for the first month or so to keep them from recieving above said damage. Atleast until mid to late April.
Hope this was helpful and good luck on everyones grows! Also, seen another guy post about thieves.. He isnt lying, keep your plants as secret as possible.
