Cooling...Would this be enough?

[blacksnow]

My cabinet is 36" W x 24" D x 48" T

Here is a pic of how it looks now (well this isn't fully painted in this pic)

I have been using t5's, but can already see next time around I want more light.

I plan on going with a 400W HPS (I think that will be plenty for this size cabinet).

I want to purchase a cooltube. My question is if I have a powerful exhaust fan hooked up to this and leave one end of the cooltube open. Will this be enough cooling for the light, and the box?

RIght now with t5's I have no heat issues. Temps are 75 with the lights on, but then again t5's barely generate any heat.

I plan on using an inline fan for the exhaust
Soler & Palau Commercial Centrifugal, Axial, Propeller, Exhaust and Supply Fans - Soler and Palau - HVACQuick.com
I'd use the TD-150 6" rated @ 293CFM on high

In my head I feel it would be enough, but looking for some insight from users with cabinets and cooltubes already setup.

Thanks in advance +rep to any replies

Sure...
Just hook up your blower with some vent tubing to your light with the other end open. Then just drill a bunch of 2 or 3 inch holes near the bottom of your cabinet.
This will make a passive intake.
Intake air will be vacuumed in through the 3 inch holes, the air will pass through your plants, then into the light, and then out of the room.

That's what I was hoping. I already have a 4" hole on the bottom back side. in that picture it has duct hooked up to it. But i plan on removing the duct. now i just need to figure out how to stop light from leaking in that hole

On the back side of your cabinet where the hole is, staple a carbon
oven vent filter on the back. You can pick up these oven vent filters for about 2-3 dollars each at HD.
Their black and they block the light while also working as a filter.

While your at HD, you might also want to pick up some self sticking foam
to put on your doors.
You want to seal up the room as much as possible. This will help with
odors and light leakage.

I had a lot of issues trying to seal my doors well =O. The way my doors open usually rips the foam, or rips it off the wood. I spent like $20 on rolls of that foam shit used for sealing doors and stuff.

I ended up going with something used for sealing actual doors that worked pretty good. I have a black out curtain hanging right inside of my cab doors to stop any light leaking =]

Believe me i got in there and tested it b4 i put my plants in. its pitch freaken dark!
