Updates pics. The only way to make the hydroton appear wet on top would be to flood to the top. I flood the table about half way up the pots, and there are quite a few roots growing out of the bottom.

The tomato plants are getting huge and the pepper is growing up. Will this be a problem besides possibly blocking any light? Even better, can I pollinate the flower on the tomato with a male cannabis plant? LOL!
