Wow, I sure would like to follow this grow, Texas. I'm in a similar climate to San Antonio, in terms of temperature, but it's much more arid here in the Mojave. San Antonio gets approximately 29 inches of rain a year, and we average about 2-4 inches a year.
The extra humidity should be helpful in San Antonio. I grow indoor-outdoor in both pots and 4 cubic foot rolling garden carts. I grow mainly Indicas, and they are way, way too broad-leafed for this intense heat and aridity.
I've found I can make it work but it is a LOT of work--it requires adding humidity (spritzers or 3 inches of gravel with water under pots) and during the hottest part of the day, when the sun is most intense, using shadecloth and also moving plants into the shade, right on the edge of the light.
Nothing can survive here except cacti and extremely small leafed plants during the heat of summer, so I augment the sun with T5 HO fluoros, bringing the plants back inside at night.
I have found that Sativas handle the heat and aridity much better than the Indicas, because the leaves are much slimmer for transpiration. But I need Indicas for pain relief and sleep, so I keep experimenting to find how I can best utilize what Hick calls, "The Great Metal Halide in the Sky" and still keep the plant roots from boiling and the leaves from turning crispy.
Since I don't grow directly into the ground, my pots are white, so they won't get so hot, and I also harden the seedlings gradually to outdoors, over two week's time.
Have you ever considered growing in a large rolling cart? It allows you to grow broad-leafed plants much easier when you can move the carts as needed to get a bit of shade, or to get them out of the rain (not a problem we normally encounter here!). And, during night time, you can bring them inside your garage or indoor veg area under fluoros.
I've attached a photo of my rolling carts, and you can see they are Indica plants, 4 per cart.
