4x4 Tent setup

Hey there,

I have dual 500w blackstars in a 4x4x7 foot tent with a 4" inline fan and carbon filter installed above the lights, at the top of the tent. The exhaust vents out of the tent and then up into the attic space. The tent is inside of a 5x5 closet.

With no internal fan for circulation, temps are hitting 88 with only the 2 passive side intakes open for airflow.

What type of fan or fans would you guys recommend for the best circulation inside of the tent? (and best ease of mounting!!)

Thanks for any help!

BaddAss Blades - Figure 8 Oscillating Fan get one our a walmart oscillating fan brand will do to!!! JB
$89.95

I'd add a second exhaust fan or replace the current one with a larger one.
