Ventalation for closet grow

I am trying to start growing some dank. I have a 150 watt hps and plan on using 8 26 watt cfls, 6500 for veging and 2700 with 2 6500 for flowering. The closet is 3 ft by 2 by 7. I want to have a good ventilation system, but not sure what exactly to do. I am going to put an oscillating fan in the closet, but how should I make the ventilation. I want to grow 4 plants by the way. Should I use computer fans or what?

Do you have a window nearby? Are you thinking to get fresh air in or just fresher air from your room? You can get cheap 4" fans at Walmart for $4 or so. Unless your thinking to use flat computer fans with ducting to force air from outside into your grow area. You could always have a fan at the bottom of your closet bringing cooler air in and then a fan the top sending the hotter air out and maybe have a fan on your HPS to keep it cooler. Just thoughts...
Growing is so much fun! I just put a few seedlings into soil for a buddy who couldn't get his to germinate

Try getting something better than pc fans if you can.

If you can't get decent fans, buy pc fans and use two for intake two for out.

Intake low, outtake high, as heat rises..

Alright thanks, I think I might just cut some holes in the top and bottom and keep one fan outside to blow cool air in and build a shelf at the top to blow hot air out. I will also probably keep a fan on the hps. Do you think this will work, and does that sound like enough light. I've been doing a lot of research and don't want my first grow to suck.

Make sure no light gets in through the fans. Also, what type of seeds are you growing? I got 1 oz. (1/2 per plant) from two plants under 3x42w CFL with 2 above and 1 in between the plants with reflective/mirrored poster board I got at a craft store for a few bucks for my first grow and they had some crystalization all the way onto the leaves.

So that is kind of a baseline.

A stronger grow with 400w HPS, nutrients, CO2, good genetics like White Widow, and very ideal conditions can give you around 4 oz.'s per plant.

If your somewhere a little below in between on the spectrum of wattage and some kind of nutes... you might get roughly 1.5 oz's for the 208w of cfl, 6 oz.'s for the 150w HPS and then add whatever the cross light from each half would add so... you work up from 7.5 oz.'s...
