hELP!!! I need advice hps exhaust problems!

Hi I have a 150watt hps and i need advice on how to build a cheap but working exhaust? I currently have 2 little desk oscillating fans in my 1ftx2ftx almost 4ft(38 inches)

I was thinking of

1. Getting two Walmart desk fans with the back open the lil silver ones thats are about 6 bucks??? and turn them around to suck air from the back of my cab or....
2. Getting a rubbermaid container and making a exhaust box using the same technique with ducting.... or
3. Getting a bathroom exhaust I only wont cus it will take up space in my room but if I have to I will.....
4. Blowing this shit off and go smoke to I pass out hummm tempting!

Advice comments please AND YES I AM HIGH!!!!

You can also buy inline duct fans at homedepot for 30 bucks, it is the same thing as the bathroom exhaust fan but alot cheaper for the same cfm. A 250 cfm fan should keep the area cool, then you could make some passive intakes and see if that maintains a cool temp. You would still want a fan in there to circulate the air inside.

I would get the inline fan from home depot or with a room your size you could get a couple 120mm computer fans and then run them off of a power converter. (phone charger, battery charger anything with less than 12v dc power) Then after you have the fans you can order a bake a round on ebay for 10 or 20 bucks and make your own cooltube with some pvc connections and some dryer ducting. . It would work great. There is a thread on here somwhere on how to build your own cooltube this way. Try it out.

yeah good call hazey, I forgot about the bake a rounds! With a home made cool tube you will have no trouble keeping the temps cool.
