It's probably too late to start growing unless you can get some clones or autoflowering varieties. You probably have 4 months at the very very most before the weather gets too cold and destroys your plants. I would recommend trying some LowRider crosses that only take 2 months to bloom out. They don't produce as much but the smoke is good and they'll be ready in time for winter.

Recommendations for GA... replace the shitty red clay with good organic soil and make sure you keep your plants watered. If you get out there once a week and check ground moisture you should be fine. During dry spells you may have to check more often.

If you have any more questions, feel free to ask and i'll do my best to help you out.

Peace!
