yeah the exhaust fan is a 500 watt centrifigal. i had to build a box which is lined with carpet underlay and insulation to keep it quiet. it blows like a helicopter!

 

intake in that room are 3 x 6 inch zhiels, alot calmer than the beast in the roof!

 

ive decided ill try a 1/3 mh and 2/3 hps mix see how it goes for fun
