update.

After about an Hour my temps rose up to 82 degrees and have stayed there steadily.

This is with 2 box fans.

The intake is pushing through a fiberglass air cleaner (the kind you use for your house a/c.)

The exhaust is pushing through some wire, A/C filter and 2 inches of activated carbon (10lbs total) across a 20x20 space.

I can't say as of yet if the carbon filter is working, but I think it is. I'm having a friend come by later and test it with his nose.

I can definitely say this. When I open the cab door the smell hits me hard. When the door is closed I don't smell anything. Previously I had a hard time smelling the plants when I opened the door because I Was used to smelling them slightly all day long. So it looks like something is working. We'll see though.

on a side note.. I'm pissed. When I went to go check my temps I spilled like 3/4 of a container of Sweet. UGH!!!!! I haven't even used it yet, I'm not sure how the cap was off/loose.
