Hey dgc, I have some black stuff growing on my radicle bags. I’ve had this before on fabric smart pots but not radicle bags. I remember h2o2 3% never killed this stuff because it always came back. I also remember scraping it off the sides of the pot too but it always came back. Ill look more into this but I thinks its black mold or something. What do you guys think? Im getting a funky smell in my veg tent and I believe its coming from this pot.
