Hey guys, I was wondering if anyone could help me out with a little problem i've got. I just ordered an Apollo Horticulture 400 w dimmable ballast and the exhaust fan on this thing is really loud. I was wondering if there was any way that i could silence this thing? I was thinking about going to an electronic store and searching for another fan to take the place of this one. If anyone has had any success in reducing noise caused by a ballast exhaust fan, please lend me your solution? Thanks in advance!
