Grow looks good so far. I'd pickup a magnifying glass at radio shack, 5x or 10x should be plenty,this will help you when determining sex as well as inspect the leaves for parasites and things you cannot see with the naked eye.

Have you just considered planting them in the ground? Might help ease the watering issue once they get larger. I've seen people make 'buckets' out of chicken wire then place the chicken wire shell into a pre-dug hole, then transplant it into the hole with the chicken wire. I've heard this helps with groundhogs and such (don't know how bad they are in Alabama).

Looking good! Also have you considered topping them to produce more yield? Especially since you are outside and you dont have to be concerned with height as much as us indoor growers.
