Sure do, I couldn't justify spending much more than $300 on dirt lol. I was going to make a post about this earlier but I forgot.. Leave the front cover off to make the most of your CO2 and filter, though I found that leaving the door open cuts the life of the carbon filter down to 2-3 months and it will start to get a little earthy smelling in there towards the end of it's life, but they're only 8 bucks (or cheaper if you just replace the carbon yourself), and it's a good enough to eliminate the pot smell without the need for additional carbon scrubbers. It does get hot though, and makes quite a bit of steam, so watch your ambient temp and humidity.
