I don't have AC here either, well the house has it but it will not be used because its just a waste of energy and all that hot air just goes outside to make it worse for desert dwellers. The old house had tile floors but no garage. I think if I stick with Bubblegum based plants for summer it will be fine inside still as they do ok in heat. The RQS Bubble Kush is a great one for warm weather here. We barely hit 100 a few days per year, so outdoor is always a perfectly viable option for the summer. I have been around lots of outdoor photo plants, but not many ruderalis besides my own.
