I know many people swear by rockwool. There also many people that hate it, including myself. The main reason is it holds too much moisture.

I currently use 3 gallon pots for my project, but I am guessing that is over-kill with ebb and flow. The weight of the hydro rocks alone would be pretty heavy for a table wouldn't it? Would two gallon pots be Rating: 5
