Now hook up the air booster to the 1ft duct and make sure the fan is pointing in the oposite direction of the bulb,join the air booster to the duct and tape it with foil tape!......at this point wrap steel strapping around the air booster and 1ftduct secure the strapping with a nut and bolt....these strappings will be used to hook up to a reflector hood or if you don't use a reflector you can still use the strapping for hanging the light from chains! it's all good either way youl'l need something to hang the light over your grow!..

So once you tape both ends of the duct to each other then hang your light into postion in your grow area ..............once hung then do the final step hook up the flex duct,this should be done once everything else is in place and lights are hung because the flex duct once streched out is hard to get into your grow box or the grow area do to tight spaces or what not lol I learned this the hard way!................so last step hook up flex duct and run other end to wherever you want to dump your heat!...........I should also mention make sure all the duct is taped up with foil tape because any air leaks,or holes from where you screwed the hardware on may take away from the air flow,which prevents this setup from running 100% effectively........
