I think the entire reason why people plant in air pots is so the air can prune the roots. It self contains roots within the container while maximizing plant growth by providing oxygen directly to the roots, and at the same time preventing roots becoming bound to the pots via the air-pruning system.

I am broke, and try to optimize everything. Do not like throwing HID lights at 12inch pots with 1/2 inch plants. Want to find the perfect way to start, nurture, and optimize, before final container.
Had very good success with late veg AF's floated out of flood and drain, and into coir. Also tried starting plants as aeroponic, to develop insane roots, then to other. Aeroponics is so easy, cheap, and effective, done DIY. Want to try it for 3 to 4 inch roots, then coir in air/smart pots.
Not trying to be a bitch. Will experiment. My thought is maybe a smaller air pot to make quick wet/dry cycles, then when rooted, open and put in a larger one, then existing roots will grow out, die and create more. I know the timing with auto's is a bitch, maybe better for photo's, or I am leaning towards long growing, larger plants (i used to call super auto, but heard it is politically incorrect).
I know most experts would agree with you, and just do things right.
