is it a better idea to get a big inline aluminum 6" fan for like $75-$80 or to just get a 6" booster fan with ducting for $30??? my tent is only 40"x40"x78"
Don't waste your time with duct boosters. You're going to need an in line fan to really get the air moving. It's worth it in the long especially if you end up setting up that other kit.
Ive got a booster fan and it works perfect for my tent. Mine is next to my bed as well and its very quiet http://forum.grasscity.com/index.php?/topic/1278292-Kevieboys-dwc-with-autos-and-cfls-first-grow
