Ok, here's the story. I needed something to prop up some plants, so I decided to use a dried catnip stem. After two days in a terrarium, I noticed the catnip stem was cover in white fluffy stuff and also had a few yellow specs on the actual stem. I pulled out the stem and any of the peat that had the white on it...none of it was actually ever touching any of my plants that I could see.
1) Is this just mold?
2) Anyone think that the plants in the tank may be affected?
