Outside Perennial

Remember, nearly all cannabis plants will need roughly 3 months to do their thing. However, extreme Sativas can take 4-6 months. If you live where Fall/Autumn starts early, you have pretty well missed the boat for outdoor growing, as cannabis does not like cold and rainy weather or the short days of Fall/Autumn when they are still in the growth stage, which they will be if you plant now. April, May and June are really the preferred planting months for cannabis in the Northern Hemisphere. Autos perform poorly outdoors, unless you want midget plants, but feminized photoperiod Indicas and Sativas and their hybrids are ideally suited for outdoor growing. Sativas can finish as late as November/December, Indicas as early as mid September and most hybrids from the end of September through early to mid October, when planted in April, May or June and before the Summer solstice in June. Once the solstice passes, this basically signals the end of planting season for outdoor cannabis. You could always try some strains with a large percentage of Indica genes at this (very) late stage of the outdoor cannabis season, these will flower the quickest, but you will need to keep them dry once they are flowering, and yields will be greatly reduced due to the ever decreasing daylength at this time of year. Hope this helps, Organoman.

You want bigger or smaller plants. Smaller go with autos, bigger photoperiods. Indica strains are generally shorter sativa are bigger
