Any opinions on my ventilation idea?

Waz Happenin' fellow R.I.U-ers!
I'm gonna be building a new grow box, dimensions:6'hieghtx6'widthx3'depth, and it will be split right down the middle, one side for veg and one side for flower, and i was thinking of running the veg room's exhaust to my hps cool tube, to blow the hot air from the hps and the veg room out of one hole on the side, what do u guys think about this idea???

what kind of lights are in the veg side? i assume the hps is the flower side, if so, what wattage? what kind of temps are you looking at for each critical area so far? (veg room, flower room, ambient room temp (the room that the cupboard is in)). where are you venting it to?

i guess what iam getting at here is far too often questions are posted, which many people dont mind answering even if theyve been asked alot, but i know i myself have a hard time looking up answers for peeps if i dont have a general idea of the circumstances they are woking with.

best of luck

and even after that, i suppose i could still say it would probably ok. your venting warm (hopefully not too hot, it MIGHT effect a bulbs lifespan, though i dont know about that) air through the cooltube, then out the side of the flower room? i imagine this would work fine so long as your ambient temp outside the cupboard (the air your pulling in) is considerably cooler than the insides of the cupboard. again though, depending on room size, might not want to be venting into the room your pulling air from.
