Hello everyone, I recently added a humidifier to my 2x4 tent. And I was using my tapwater after a couple days I noticed I was building positive pressure and saw that my carbon filter(didn’t use the sock) was getting clogged with white powder as well as my exhaust vent cover. I’m wondering if this is what powdered mildew is? It’s not on any of the girls or anywhere else in the tent.
is it as easy as changing my water source? I’m a reefer.
