where did u get the strips at ? and the money issue thats to be expected going into trying new things. and the fan u have to buy anyways really for exhaust for the right set up so the things ur buying u would have to buy anyways.looks like u were going in half cocked or skimping to as low as u could go hoping it would'nt need more than that it's no biggie.i have learned long ago that the stuff that should be small end up big and the big well...it just stays big but the small end up biggest lol i know how it goes.
