Hello Buk,

For my cool tube, I have a 50 CFM fart fan. It has a 2" or 2.5" outlet, then I step it up to the 4" dryer hose. Inside the cool tube, I have only one 400W MH bulb. I still haven't installed the 600W HPS. The 'run' from the fart fan to the inlet of the cool tube is very short (less than 12"). The longer your 'run', the more restriction/friction the air has... so try and get your fan as close as possible.

Of course, those restrictions/friction losses are less important if you've got a Dayton or some similar type of fan.

Something tells me I'll have to upgrade the fan when I install both bulbs. I haven't recorded temperatures (inlet/outlet) of the cool tube, but the outgoing air is warm, not 'hot'. I think that the 50CFMs won't be enough when both 400W MH and 600W HPS are in there... we'll see.

BTW: I did send you a friend invite, but I don't have you on my list. I'll re-send it. Dude, I'm sorry I don't post my gamertag, but I'm semi-paranoid with posting it here. I mean, the math would go like this:
-turtle420 grows weed.
-turtle420 is JOHN123 in xBox Live.
-Feds: Let's ask Microsoft who paid for JOHN123's subscription of xLive
-turtle420: Oh fuck!

Understand my concerns? But not to worry dude, I'll re-send the invite as long as it's necessary. I need to play a little bit more... I got my ass wooped in Zanzibar the other day.

I'll update in a little while guys.

Best Buk,
