Ok right now I have it hood then my fan attached to hood then ducting...I need to mount my fan?
Yes, the ducting is going into the room next door...
ok u have it hood ....then fan then ducting out
u want the fan set/mounted some place where it is safe(it will move push and pull) and the heat from the light can bleed off............the next part is u want to try to advoids bends and long streches of ducting ............the more the bends or the longer the ducting the more power is lost (after 20 feet u can aff a booster fan for long streches )
i personally have mine mounted to a peice of wood that i attached to 2 studs ......outside the tent (small fan under it blowing up at a angle to move air between 2 tents)..............the ducting in the tent is normal flexie the one after the fan to the venting is insulted flexie (mine needs it for the temp to be controlled in sealed room in a tent )
