Please help me get inexpensive ventilation fans etc.

Ok still trying to piece things together. I have questions about circulation. For instance if I buy a small grow tent, I assume it will come with openings for exhaust and intake air?? If so, I also assume I will need to buy these intake and exhaust fans separately? What is a good online source? Do the fans come in sets of two or will I buy two seperate fans? What minimum sizes will I need for exhaust and intake? Keep in mind I was only looking to ventilate a small 99 dollar tent with CFL lighting. Finally will the exhaust hook up to a carbon filter?

If you are running cfl heat should not be a major issue. Ebay is great, and cheap. inline fans are very quiet and efficient. If you do an inline 4" fan there will be no need for a intake fan, esp in such a small tent. Just hang the filter at the intake side of the fan, and duct out the exaust side. Remember hot air rises so hang it high. Get some cheap fans at walmart for air circ. in the tent. Hang thoes high as well. Hope this helps! Good luck!

I grow with cfl, and have no problems controlling heat. I took a couple of $7 desk fans from walmart and altered them to be mounted like a regular inline fan (just no ducting). They're flush mounted on the walls of my grow space. Has worked really well for me so far. If I can find the time I'll re-post with a pic.
