I used a 3 ltr bottle & drilled holes in the bottom with

my dremel , b4 all this i picked up some filter floss about 2 oz

And about 5 pounds of active carbon " I only used 3 pounds "

& spilled the rest on the floor.. (yikes) anyways


Ok next I poked about 3 " of filter floss down the mouth hole

& used my funnel 2 pour in the carbon . then caped it off by another

layer of filter floss .. it cost me about 20 American dollars .

& it works .. But keep in mind that I have a small 3x2.5x6 foot

enclosed grow box . All I did was put a spade bit in my drill-

drill a 1 " hold for the air to be exhausted out put my lil

computer fan inside the box so the air blows up& out

going through the filter . so far it works just fine I'm

3 almost 4 weeks into 12/12 & out side my grow box there is almost no

smell ..Inside well that a different story ..... :D
