I have a 6in inline exhaust fan for my grow cabinet. I'm in week 5. And plants are starting to smell. I need to know what's the best method for making my own carbon filter. I've seen a bunch of DIY ideas on here but which one do most people use. I tried the Zen one but it didn't fit my fan. I'd appreciate any links or vids u guys could give me. I need to do this ASAP. I also have a question space inside my cabinet is limited. So can the filter actually go on the outside part of the fan? I hope so. That will give me a Lot more options.
