Hey all, im going to be doing a stealth grow in a [29-1/2in W x 16-1/4in D x 60in H Cabinet. With a 600w HPS( I had originally wanted to do a larger grow, or woulda just got a 400w), and a homemade bubble hydro system. Im am trying to decide what exactly to do for ventilation because I see this becoming a problem fast, looking for input, if i should use alot of computer fans, or vortex, or whatever, so once its made i dont have to worry about any problems. Thnx
Heat problem inevitable?

Have fun with that...
I'm doing a 31"x31"x65" with an air cooled 400w. I have 300+cfm fan for exhaust and a 200 something cfm fan for intake. My temps run at 77-80* with 68* ambient.
Yours will probably run in the close to 100* with the same setup unless you vent outside.
Oh, and you do realize that a 600w in that space is ~185wpsf, right? Half of that would be enough.

Damn, thats a big light for that size room.
6" air cooled w/ vortex fan. Ducting drawing air through the out side with the intake flange of the hood not connected to anything - will draw the air right out of the room and across the light.
You will need to vent to a separate location. Venting in and out to the same room will greatly increase the whole room temp and render ventilation ineffective.
Alternatively,You could install passive intake ducting to draw cool air from a different location(basement?).
