I would try the squirrel cage by it self first. I imagine you will suck the air from the box, threw the hood and out of the box? That should work. What are you using for intake?

BlueBear Reviewed by BlueBear on . 400w hps Hi all, New grower here and I a question about my setup. It's box I built thats 3' tall by 2' deep and 3 feet long. That's a totally of 6 square feet and 18 cubic feet. I recently purchased a 400w hps that is air-cooled with ducting. It has an attached ballast and I'm running a 465hp squirrel fan thru the ducting to cool the hps bulb. Now my first question is, will this fan keep my grow box cool enough? If not would some passive intakes (ie2-3 light-blocked holes on the bottom) and Rating: 5
