Unfortunately I don't have step by step pics for this, but I'll try to describe it as detailed as possible. It's really very simple and works like a charm!
Assuming you have ducting running out of your grow space, lamp/reflector, etc, this will work well for you. Here is what you'll need:
1) Marineland Bonded Filter Pad (this shit is overpriced at Petco and Petsmart - about $5 for 312 sq. inches but it holds the carbon perfectly) Marineland Bonded Filter Pads at PETCO
2) Filter Floss / Filter Fiber (about $2) Petcetera Filter Fiber at PETCO
3) Activated Carbon - I got the 14 oz. and it will last for a very long time ($7.97) Aquarium Pharmaceuticals Activated Filter Carbon for Fresh and Saltwater Aquariums at PETCO
That's all you'll need!!
1st Step - Grind up a nice sized pile of the activated carbon. They are usually in pellet or pebble form, but in order to expose as much of it to the air as possible, you'll want to grind it into a granular, even powdery, consistency. I used a spare coffee grinder I had laying around and it was perfect. If you don't have a coffee grinder, you could do this by grinding it between 2 bricks or stones (mortar and pestel style like the native Americans used for corn)
2nd Step - Cut a circular piece of the bonded filter pad to be about 1" in diameter LARGER than your duct line. The bonded filter is actually 2 types of material bonded together, one blue and one white. Take several healthy pinches of the ground carbon and generously sprinkle into the BLUE side of the pad. Work it into the pad by tapping, shaking, twisting etc. Keep adding carbon until you feel it's loaded up. Gently tap excess out, but make sure it retains the majority of it. It holds it well.
3rd Step - Take a good sized gob of white filter floss (which is just spun, white polyester or nylon) out of its bag. You'll want enough to fill about 6 - 10 inches of your duct line, even more if you like. Take that gob and roll it in the remaining pile of your ground carbon. Make sure you get it nice and "dirty" with carbon dust and particles. The floss doesn't hold as well as the blue pad, but if you work it in, it gets nice and dirty with carbon.
4th Step - Take the circular piece of loaded up Blue filter pad and carefully place it in your duct line, with the blue side facing "in" and white facing "outgoing". If you cut the extra inch like I mentioned, you will kind of have to scrunch it into place. Place it far enough in that you'll be able to put the filter floss in after the blue piece is secured.
5th Step - Take the dirty filter floss gob and stuff it into the duct line so it just leaves you enough room to re-secure your line to wherever you're exhausting from (reflector, grow box, etc.)
That's it, you're good to go!!
ONE IMPORTANT NOTE: Depending on the power and suction of your exhaust fan, you'll want to make sure the pad/floss don't get sucked into your fan. This can easily be achieved by running several pieces of fishing line through the blue filter pad needle and thread style, then the tag ends can be run up and out of the duct line and secured by your hose clamp.
If done correctly, this will greatly reduce odor being emitted from your grow area without compromising air flow much at all. I have yet to verify the life of the carbon, but I'm guessing a monthly change will keep it working like a champ.
CHEERS!!
