Ventilation for Small Vegetating Compartments...Plz Help

I made myself a grow cabinet for vegetating under T5s. The cabinet has 2 small compartments, each powered by four 2-foot T5 bulbs. I plan to vegetate Northern Lights and/or AK-48 to a height of 8-10 inches, and then put them into a separate grow tent under 12-12 HPS for flowering.

My problem is ventilation. Both vegetating compartments are pretty small. The smallest fan with a plug-in cord I can find is the Eco Plus 3.25" 25 CFM fan. Assuming I use one for each compartment, then each compartment will exchange air 6-7 times per minute. Quite a lot.

Is this too much air exchange? Are there lower CFM fans that have plug-in cords?

Thanks for your help.

Put one on each side of your cabinet. One bringing air in and another exhausting air. You can never have too much air circulation as long as it's not blowing the plants over. What you want are called Axial Fans (computer fans). You can get them online real cheap. Hardwire them yourself.

also put one high and put one low it will vent over the plants more....................... like phillip said with usualyy intake air up top and out take or exhaust at the bottom fans arent eficient the other way around

For 2 plants this system is good? How i set up the exhausting system?
