DIY CARBON FILTER ROUND 2

[texas grass]

So where you telling us that you have some smell leak problem ?

i did with the other filter. the other filter was the type everyone else has. i made it 2' long and inside tube was 5" and the outside was 8". i had 15lbs of carbon. and i could smell some buds. thats why i change my design. now im using less than half the carbon and getting better scrubbing action
