Very simple and compact (height) carbon scrubber idea


Hey guys, so I’m sitting here planning my next grow box, which will be about 5′ high x 2′ x 2′ – and I’m thinking of how I want to do my carbon scrubber. Then it hit me, I don’t know why I didn’t think of it before.
I’ll try to explain this as easy as possible:
Ok, imagine a 5′ x 2′ x 2′ box. At the top of this box is a good PC Fan attached to an exhaust hole. Under the pac fan, maybe about an inch away is a stretched screen or mesh (over the full 2′ x 2′ footprint). Basically, if you know what a silkscreen looks like, imagine that at 2′ x 2′ – here’s a picture of one:

but basically, this screen sits below the exhaust fan, and all you would have to do is pour an inch of carbon on top of it. So it’s a 1 inch layer of carbon, on top of a screen, with the exhaust on top of this.

I can’t see any reason this wouldn’t work just as good as a normal carbon scrubber, as long as all the seams are air-tight and the only possible way of airflow is through the 1" layer of carbon.

Does that make sense? It would actually be really easy if I’m making the box to have a removable top, where you can fill up the carbon screen.

It’s so simple, and would only take up an inch of height!
What do you guys think of this? I think I’m gonna try it out. This would allow me to utilize much more space. It would actually, probably only work with a pc fan exhaust, though.. unless of course you have the room above the screen for an exhaust fan. I plan on using this with LED lights, which is why I’d only be using a pc fan or two, so I wouldn’t be concerned with cooltubes or anything.

Anyway, I figure the screen, then the exhaust, then a light trap, maybe 6" high at the very top of the box would work good. Has anyone tried this before? Is it too good to be true?

I will definitely make a DIY thread when I start my box if I go this route!
