Disclaimer: Amateur grower--- I live in Albuquerque, NM (pretty damn hot but not Tucson). I've had success so far with G13 Labs' Sour Candy. It's a medium tall, not too branchy, stretchy, and narrow-leaf plant (THC 12-15%). It's supposedly Indica/Sativa hybrid and the genetics are sour diesel and bubble gum. This one is looking REALLY good so far, close to ending it's vegetative state. My tomatoes got massacred by the sun in early July and I had to put a shade cloth over them, but NOT the sour candy. It seemed to take the sun just fine. It did seem to take off after we got some rain and things cooled down, so, when I do this again next year, I'm going to use a really low-blocking shade cloth (maybe 25). I have high hopes (literally) for this one because if it fails I'm pretty sure I'm going to end up with a really awful yield. I'm also growing DNA Connie Chung; it's doing just okay and I may not do it again next season. It's a broad leafed plant. I also tried several dwarves without much success, but I intend to try them again cause I made a few mistakes (Buddha Seed's White Dwarf, Easy Rider AKA Lowryder, Afghan Kush Ryder, and AK47). Only the White Dwarf made it and it didn't thrive. I made a green dragon out of it and it's potency was weak.
