@Donaldj, @tonyb, I was not going to stop dropping ice packs, where I live I need the ice packs or the water will get up there (>73deg.). What size of air stones are you using, my stones are 1 1/2" x 1". Even through they are of the same size they do not put out the same. I am having a hard time finding what will work better. I have tried 4" round, 1/2 x 4, and 1/2 x 6 and they do not put out any better. Also the placement of the stones, should it be centered or set to one side? I notice when I get a large root sys., if it is centered, the bubble's are not making it to the surface and not splashing the bottom of the basket and the roots at the bottom of the basket look a little dry?
I have one more question, how much water should I be using in a 5 gal. bucket. When I put a seedling (about 3-4 day of germinating) I bring the water up to the bottom of the basket, and use a bubbling water ring on a timer that is doing very good. After a week of that I have a good root sys. started and the second wk. they are ready for nut's. That is where I am not sure where to be with how much water. Right now I am putting 3 gal. of water. It puts the water 1" - 1 1/2" below the basket, is this ok??
