that carbon layer is pretty thick and might be too restrictive, how many sq/in of carbon is exposed on the 'surface'?
The S&P mixed vents simply do NOT suck like a centrifugal such as Vortex, Elicent, etc.
I'm running a 250 HPS with a TD 100X at 100 CFM. My 1" thick DIY scrubber was more than it could handle so I reduced the core thickness to 1/2 inch (4" inner core-5" outer core) which has lasted two single plant grows (22x29 inch ScrOGs) so far.

Super Stealth grow and a question
Super Stealth grow and a question
I have flowering chamber (still in progress) and vegetation chamber. Both air exhaust are centered in a space that doesnt have much "open" space to room to be able to cool down. What do you suggest? I wanted to be exhausted directly to the room but when its stealthness on the first place I have to go with compromise.

You're going to have to reduce that 2" layer of carbon. Spread it out more, but keep it thin. That should keep the air flowing well while maintaining odour control.

I agree. But from what I've read you'll need at least an inch for the scrubber to be effective.

One thing that made a ton of difference in my grow was to put plexiglass under my CFL lights, keeping the heat somewhat contained. I went from temps in the 90s (even over 100 a few times) to never getting higher than 83.
In my brief experience with micro grows, its the strength of the fan that has made all the difference in removing excess heat...I have a Delta fan that is 151 cfm with a pc case with 161 watts inside...that fan sucks all the heat out....my average temps are 77-79 tops...
Thats with a scrubber too..sounds like if you want to keep the lights, which you shouldn't have to get rid of, use a very strong fan with cfm's in the mid to high 100's
Redgreene's thread on ventilation might help you too, to figure out your inside dimensions of your box(which you know), then finding the right combo of intake hole and a good exhaust fan to remove excess heat..
good luck!

I'm on grow #3 with a 1/2 inch core. I don't expect it to last 2 years but, it's getting close to one year.
For a 4" fan you want 25.12 square inches of intake. Intake is double the exhaust. One 4" exhaust, two 4" intakes
The more surface area, the thinner the carbon can be, to a point. Mine is about 3/4ers of an inch, probably half an inch at the thinnest point. Zero smell from the first run with 2kg of carbon.
Surface area should be your number one factor in deciding a carbon filter. I think this 92mm pc fan is about the same specs as your S&P and it blows just fine through 1.5 inches, because the filter has surface area.
My suggestion is to make or buy a filter with more surface area. Good luck.

My filter is the basic DIY SugarBear style. So far working like a champ. It is prolly only about 1/2 inch thick carbon.
