400watt mh/hps Bagseed Grow

Any hints?

How much was your carbon filter? And where are you venting too? And how well does that carbon filter work?

Carbon Filter and fan were a combo for $140
Currently the air just recirculates up and flows over the bulb of the HPS
Cool down the light dramatically
And yes the carbon filter works amazingly! My neighbors aren't that far away and so far nothing, no smell what so ever in the entire place.

update?
