My loft grow setup consists of the following, 1 125w blue enviro and various heated props for vegging in and a clipon fan, for flowering i use a 400w hps with a son t bulb, there is a 125 inline fan for extraction bit noisey but not unworkable this vents out of the loft through a vent tile, a shiny new 12" osc fan for inside and a 100 inline fan for intake, also picked up a heat mat for growing during the winter months keeps the pots a nice steady 10 degrees, i have also partitoned off the grow area just to hang the door and its done (only been at it since last year
here are some pics hopefully
