How To - Carbon Filter

Does anyone have any tips on increasing airflow through the scrubber?

I have a 6" 250cfm inline fan hooked up to a cool tube with a 250W HPS in it and my filter at the end. It goes tube -> elbow -> fan -> about 6' of duct -> scrubber at the end.

The temps are too high (> 30 C) with the door closed so I have been leaving it open. Now I'm closing the door but have removed the scrubber. I plan on buying a Vortex fan to fix the problem, unless someone here can help me out.

So has anyone had this problem before? Any ideas?

edit: The scrubber is the same size as this one, 4" and 6" and the roughly same length. This means I have 2x 4-6" reducers at the opening of the scrubber which probably inhibits flow. :( My fan and duct are 6" and that was the only way to fit it without making a giant filter.

I am going to make a grow box when I move into dorm for college. Looks like I am going to be using up all my prepaid meals while saving my "food money" to buy seeds and stuff lol. I better get a 1 room dorm so I can grow... I am also going to be growing shrooms for my friend in a tuberware box.

How much activated carbon is used in this carbon scrubber?

Good post greAt instructions am in the middle of solving my air and odour requirements and it was a great help. Have a couple of 4" fans by 12vthat i stripped off something a while ago and needed the filter instructions and the kittie litter is gonna be a great saving

Another lover of the homeade carbon (used silica gel kitty litter here) filter here! Thank you Bodom for posting it!!

This sounds like an awesome device! One quick question....When I do my closet grow next fall, can I have this set up to where the fan sucks the dirty air through the filter, and then exhausts the filtered air back into the closet? I just don't have way to vent to the outside for obvious reasons (heheheh). I can give good enough ventilation and CO2 and such, just no-where for the smelly air to go. I just worry that others in the complex will notice the smell, even with this scrubber... Think it'll get the job done?:bonghit::baggy:

As long as you got ventilation, it will be fine.

you could try to get the big big mama pantyhouse. :jointsmile:

otherwise just think of something

it just has to be small enough holes so as to not let the carbon/kitty litter fall out. you could probably buy some mesh screen that would work also.

good luck

I missed something does it just sit in the grow room??? or does it connect to a fan? Would this also help with a poorly ventalated room. I mean can it help in the plants breathing by removing the impuritys, and helping the plant gain more bulk. Another form of Co2 despencer. . .
