Hey im at latitude 39 N, and was wondering if anyone with experience in the latitude could tell me when flowering usually starts for them.
There is a sticky which addresses this, but... You are asking 2 questions...altitude and latitude. Anyway, you're obviously in Colorado. You should see preflowers in mid August and flowers by early Sept. Progress depends on a ton of factors.
sorry i meant my latitude in the thread title, and no the sticky adresses this question but does not talk at all about when flowering periods actually start anywhere in particular.
