Ok this seems like it would work to me. WHat you would use would be one of these systems http://www.discount-hydro.com/productdisp.php?pid=561&navid=4 I know that it is a propagation unit but since you are keeping the plants small would it work for a SOG grow?
Just an opinion, but I think root mass would quickly become dense enough to block the machine's ability to fog. Foggers are a form of spray nozzle, and eventually roots would block the spray path. If you threw in some air stones and hooked them up to pumps, you could make it an aeration/DWC hybrid SOG table. But I could be wrong. Very.... very wrong. E4A2S
.. i dont see why it wouldnt work, other tha reason stated ^^abouve^^.. but as he says, DWC that mofo and you got yerself a SOG table.
