Bubba,
It looks like you're using a 5-gallon lid with a built-in 6" diameter mesh pot, right? Doing some research on this, I found these are available in 6", 8", and 10" mesh pots. Based on your results, do you think the 6" version is best for tomatoes? I'm thinking of trying some kind of hydroponic setup like this myself, probably a drip type system.
