I used a 4" coffee can you could use a larger one if you want to. Cut the bottom out with a can opener. (pic 1)

I got a peice of gutter guard from the hardware store about $1.70. (pic 2)

Cut enough to fold around can. (pic 3)
Fold around can. You will need to cut slots about every 2". After folding around can you can tap with a hammer to compact and remove sharp edges. (pic 4)

Add hose, alum. tape, and hose clamp. (pic 5)

Hang up and attach to fan. (pic 6)

Then put this carbon bag in it. https://www.rollitup.org/grow-room-design-setup/63004-my-3-carbon-filter.html

wow. Will it work?

Yes, it works. Check out the link for the $3 bag I put in it, they rave about it.

Thanks, I had the basic idea but my wife refined it and made it much cheaper than the way I had planned it. She says I must give credit, where credit is due. So thank you brilliant, wonderful wife!

how to get air to move through it just a regular fan??

I'm using a 6" blower with 300cfm of air flow. You could go smaller I had heat problem from the 400 watt light in 3-1/2' x 3-1/2' x 7' cab. that I made.

I have the fan in the cab. you can kinda see it in (pic 6 of post 1). it sucks the air out of the cab. and blows it thru a 4" dryer hose out of the cab. and out a window on the second floor.

Still no smell??? I wanna make something similar but i wanna attach 2 of these coffee filters drill holes (1/4inch) like 50 of em on each can, cap one end, cut the bottom out of the other so they attach, wrap it in that gutter guard, and then insert 2 or 3 of those bags to wrap around the diameter of the coffee cans, while the guard holds it in place and reinforces it.......i wonder if this will be have enough surface area to allow 400 cfm to pass through.......if not I'll probably spend a few bucks and buy a sheet of sheet-metal and probably roll one of my own dimension and length and drill the shit outta it.

Regards =)

Still no smell, and I just harvest 3 40"+ plant with 15 1/2 oz total.

I Found This On the Inter Net Somewhere And thought ill Share It Here WIth yall



[SIZE=+2]TO HELP YOU FIGURE WHAT SIZE FILTER AND FAN YOU NEED, HERE IS A SIMPLE WAY TO FIGURE IT OUT.[/SIZE][SIZE=+2]

[SIZE=+2]WIDTH X LENGTH X HEIGHT = CUBIC FEET[/SIZE]

[SIZE=+2][SIZE=+0][SIZE=+0](TO BE EFFECTIVE-THE AIR IN THE ROOM SHOULD BE EXCHANGED AT LEAST ONCE EVERY 5 MINUTE) [/SIZE][/SIZE][/SIZE][SIZE=+2][SIZE=+0]
[/SIZE]
CUBIC FEET / 5 MINUTES = CFM NEEDED

EXAMPLE:
8 X 8 X 8 = 512 CU FT


512 / 5 = 102 CFM NEEDED

[/SIZE][/SIZE][SIZE=+2]ACTIVATED CARBON [SIZE=+2]Research Studies and Facts [/SIZE][/SIZE][SIZE=+2][SIZE=+2]

Activated carbon is non-toxic. Basically, bituminous coal is totally carbonized by being subjected to high temperature and then is exposed to high-pressure steam, which causes the carbon to fracture, with almost infinite microscopic fissures that retain passing molecules. There are so many of these pores that one pound has a surface area of 60 to 150 acres. This carbon is unwashed so that you can be assured it is virgin carbon and not recycled (regenerated) activated carbon.
Some carbons are activated or washed with phosphoric acid, zinc chloride, or potassium hydroxide. These chemically treated activated carbons could leach phosphate (an algae promoter), heavy metals, or alter pH.
This activated carbon is NOT acid-washed.

SOME CARBONS ARE POWDERIZED, HAVE ADDITIONAL TREATMENT AGENTS ADDED, AND ARE THEN EXTRUDED IN PELLETIZED FORM. THIS CARBON IS IN GRANULAR (i.e. crushed char which is then sieved by particle size) FORM AND HAS ABSOLUTELY NOTHING ADDED TO IT. THIS CARBON IS USED FOR VAPOR AND LIQUID PHASE. ACTIVATED CARBON AIR FILTERS
[SIZE=+2]Activated carbon air filters are the most effective type of filter against chemicals, gases, cigarette smoke and other odors. [SIZE=+2]

[SIZE=+2]Activated carbon air filters trap odors and chemicals in highly adsorbent granules (or pores), which look like a hard scrub brush.[/SIZE]



Activated Carbon is effective at removing the following types of chemicals:​

Acetaldehyde Cyclohexanol Hydrogen fluoride Paint & redecorating odors Acetic Acid Cyclohexanol Hydrogen iodide Palmitic Acid Acetic anhydride Cyclohexene Hydrogen selenide Paradichlorbenzine Acetone Decane Hydrogen sulfide Pantane
