I figured I would post this here for you
@gratefulredhead instead of in a message in case anyone else from AZ has other outdoor growing suggestions or wants an idea on how to take advantage of the 2 outdoor grow seasons we have here.
Like Buds said, steer clear of growing from May to September if you live in the really hot parts of AZ. I managed to grow some autos outside in June and July this year. They were sunburnt, crispy, and had very airy buds. That was with misters and a shade canopy, not worth it to try again in my opinion.
For photo period seeds, I'm actually starting my spring plants indoors right now. I'll veg them inside until February when I will bring them outside to flower (usually refered to as a spring light deprivation grow). This fall I did the same, I started the plants indoors and vegged them until September when I will took them outside to flower. You'll want your photo period plants outside to start flowering by early February or by the end of September. If you wait too long in the spring the increased light as you get towards summer will mess with your plants and you may have to do some sort of light deprivation to get them to finish without becoming hermies or revealing. If you wait too long in the fall (like I did this year because of the heat that never ended) you'll end up too far into December with the cold and limited light.
Auto flowering strains I would look at the seed to harvest time the breeder gives and add 2 weeks to it. For spring planting, I wouldn't advise going past May 1. I would calculate using the growing time of the plant to find when to plant the seeds. So for example you have a 65 day seed to harvest autoflowering seed, add 2 weeks as a buffer, which gives you approximately 11 weeks of growing. So 11 weeks backwards from May 1 would put you right around Valentines Day to plant your autos outside at the latest. For fall, I like to plant around Labor Day. Usually by then things are cooling off and it keeps you from harvesting too far into December.
I hope this helps give you an idea of growing outside down here. Having 2 flowering seasons is great you just need to know how to take advantage of it.
