I am about to start on my new grow room.

Plans go something like this SWC 3 x GT100 bottom tanks 9 plants per tank, 6 x 600w cool tubes, 8" intake fan, 6" and 8" running the cool tubes out take fans into an 8" inline ozone generator. I air feed to the 3 x SWC will be from a side channel blower rated @50m3/hr 0.6bar running into soaker hoses with a 200mg ozone generator air pump feed to keep nasties at bay.

Good place for soaker hoses of different types is http://www.nccsupplies.com/
