in order for your passive intake to do its job you need a decent exhaust. how big is your cab? i would use at least one of those for exhaust and one blowing on or over the plant(s). if you have a fan for inside the cab already then use both for exhaust and your prob gonna be all set. unless your cab is bigger then like 2x2x5.

sorry i slipped away for a minute. i think the two comp fans will work in 2x2x5. any bigger and you need real fans. i might even be wrong here, im totally guessing at this. i have used pc fans before so i have a clue what im talking about.
how big is the intake? maybe do one intake one exhaust and cover the passive?

i think that may be more effecient in your case im not sure

1. exact cab dimensions?
2.size of intake?

i use those cfls for clones and mine are only 90 watt and they get hot especially i think the lower kelvin ones. so it will be important to knock this issue out. do a trial run.
