Hydroponic Heretic
My girls should be starting to smell in a couple of weeks, and not being able to afford a proper ventilation system yet, I have decided to build a carbon filter. I will be using only materials I have here at home, other than the carbon itself. I ordered 2.5 lbs of activated Carbon, which should be here by Wednesday. I got the Marineland Black Diamond Premium activated carbon. It cost me $20. Free shipping. It is made from Bituminous coal, rather than the coconut shell product that you often find. My research indicates that the coal based activated carbon is superior to the coconut shell stuff.
I have only just started, so I just wanted to get a thread up to document my progress. I will be completing the system over the next several days, and will update as I go. I will also be updating after the fact to let you guys know how this design works.
I will be using my Honeywell Turboforce fan. It is rated at 350cfm. Yes, it is a regular axial fan. I currently have it at the top of my cabinet, raised up into a hole in the top. It creates some SERIOUS negative pressure on high, so I don't think it is going to have a big problem pulling through this design. I currently run it on medium the way I have it set up now.
I am using a square bucket that I have here at home. It is about 9 1/4 inches square, which is also the approximate diameter of the fan.
For the inner chamber, I will be using a tupperware container that sits inside the bucket and leaves a 1 or 1 1/2 gap on the sides. The Idea is to riddle the buckets with holes, use some screen that I have here on the inside of the outer bucket, and the outside of the inner bucket, and fill the void with the carbon. I have drilled the larger holes in the outer bucket, at this point, and will also be drilling smaller holes toward the top to make sure I get as even of an airflow as possible. Basically, if you drill all large holes, then the fan will mostly suck through the holes closest to the fan, so you drill smaller holes the closer you get to the fan itself.
Here is a pic of my starting point.
I will update more as I progress with the build. Wish me luck! Assuming it pulls air and functions on a fundamental level, we should know if it works for the odors in a few weeks.
