Hi all,

 

So this is my big introduction... And my tutorial...

 

I'd like to outline how to build a Carbon Scrubber for the DIY'er in most of us..

 

So, let's get to it..

 

Most of the materials are EASY to get at the local HomeDepot in the HVAC area.. Here is a pic of the general materials.. This tutorial will outline a 4" version, but making a larger (6"-8") would only require adjustment to the process..

Ok general parts list:

Carbon (I bought a 5gal bucket on Ebay, fine kernal, it'll make mutiple filters, it's worth it)

6" to 4" reducer

6" cap

4" plug/cap

1/2" hardware cloth

window screen

wire ties

sheet-metal screws

tools

 

Glue/screw the 4" cap into the 6" cap..

Measure out the HW cloth, giving enough extra to overlap about 1" or so...

Make a tube, and cover in window screen..(the outside of this tube)

I screwed 4 sheet metal screws into the reducer, right where the 4" section begins.. This I feel is important, it gives something for the screen tube to stop against..

I even went as far as to capture the screen with the screws..

What you end up with...

Now, back to the cap... Measure out what screen is needed between the cap and reducer..

Now the outer tube..

Starting to come together...

Now the outer tube needs window screen on the INSIDE.. Netting you this..

Sheet metal screw the outer screen into the reducer..

I like to seal the screen to the reducer with some silicone, just to keep the carbon in place better..

Carbon time..

As you fill, tap on the sides and whatnot, to get the carbon to settle as much as possible..

Install the cap... The center cap centers and seals the top of the filter for you.. add a few sheet metal screws to hold together..

Finally, get out the shop vac, and possibly an air compressor... CARBON IS DIRTY.. vacuum and spray the filter, you might be supprised how dirty is is.. lol..

 

You'rs DONE.. connect to your duct fan and enjoy..!!! Understand that a carbon filter will KILL your CFM.. I'm using a CHEAP 80cfm duct booster fan, and it's not enough, I might be getting 40-60CFM out of this set-up... A larger filter WOULD flow better..

how important is it to hook a fan up to the carbon filter for a 3-4 plant grow?

 

 

It all depends on the strain for one , grow location for two and personal preference is the last choice .No matter many use them regardless for security issues . Only you can answer this question my friend as you hold the variables needed to answer .. Good luck.......OD

If the 3-4 plants are the cc99 strain then no fan (or for that matter, filter, needed at all). For lemon cake or skunk or really, all sstraains but cc99, a fan is vital (unless you're advertising your grow room like some bakeries that waft the odor of cinnabons out to the general public to induce buyers to enter).
