its clean simple and effective. i used a course carbon as i am using a small 50cfm inline fan if you are using i bigger fan i would use a finer charcoal.
the list
4" roof vent cap 10 bucks
4" vent extention and cap. 3 bucks( or free, i just took the plastic cap of and put the tube inside the vent cap, and went to self check out.)
carbon 8 bucks
window screen already had.
tools
flat head screw driver
hot glue gun
tin snips
pliers
elbow grease
heres what your looking for at the depot.but notthe charcoal
you need to pry the top of the vent cap of with the flat head.
then hot glue the screen to the inside of the vent to hold in the charcoal.
now take 4" extention witch must be really like 3" and 9/10ths cuz it slides in vent cap. you need to cut the midel so there are two bands one at the top one at the bottom. hard to explain and it was even harder for me to do.the wrap it in screen and glue in place.
i had shitty tin snipps and it was awful. so its a little mangled.
now glue the extention inside the vent cap
i filled in the bottom part with pollyfill as air wont flow there,now fill with carbon.
i toped it of with pollyfill to keep the carbon where it should be wile i pry the top back in place
and thats it. it should look just like it did when you got it.
here it is in a grow cab.
