the 600 is all cheese lol. the box is a mdf box lined with foam rubber (2") that houses the fan to cut down on motor noise. heavy though. i did a tutorial awhile back but theres a few around...
the mother tent has a 4in dayton axial and passive intake and a 4in eco pulling through a 4 in filter... i have a regular 8inch sunbeam fan for the intake on the big tent and a 6inch eco supreme pulling through a 6 x 24in phresh filter. small tent is a 6inch dayton axial intake 6 inch vortex exhaust through the regular size 6in phresh. seedling/clone tent is another sunbeam intake and a 4 inch eco unfiltered exhaust. in the big tent i have a 18inch floor fan standing in the corner rotating, canopy fans set in other tents are 6 inch clip ons. hope that helps!
