Carbon Scrubber and Light Trap

Check my thread in my sig to see what I did for a light trap. I do reccomend using ducting without reflective surfaces in the middle though as it releases some light from the cab. I will be perfecting that.

I would also check out Dark Room Louvers as they can be used as a light trap for your intakes.

For exhaust, you shouldnt have light if you are going to use ducting and a scrubber. There are many DIY mini carbon scrubbers for the type of application are you asking about. If you are to purchase one, I recommend a small 4" flanged filter and you can get them about 8" long. Dont cheap out on filtration. It may seem like a lot of money to start but if you want a stealth grow, it is necessary to have all that dank air scrubbed out and cleaned before releasing back into your room.
 
Does anyone sell Carbon Scrubbers and Light Traps for Stealth Cabinets?

If its less than 100 cfm, then its almost strictly DIY. The 4" diameter, 7.5-8" long carbon filters are great, they run about $30-35. [Although, you can build a copycat, for pretty much $10, depending on the cost of your AC]

If the cab is bigger than 5-7cf, I would say the 4" filters would work pretty good, but it would be way overkill for my 3.5cf cab.
