My advice.. Get a hybrid that isnt too far bred. Pick from a selection of those females.. Learn that female and her needs. She is your woman.. Your reason to exist is to meet her needs. Slave to her if you must.
An indica dominant will be shorter flower, hopefully f1 hybrid vigor strong, and need less intense light than my partial dutch bred landrace sativas.
(My queen roots fast and grows better and easier than anything else in my garden freebie up to spendy 17$ seeds.. She is a hungry lady however. Mother or clone.)
Edit: Why do you need an auto in arizona? 6 weeks with my lady can make subpar super racy heartbeat stuff.. so.. Im from the standpoint of control over when and if flower occurs to be clear.
