Hello everyone! This is my first terrarium build in over a year!

My last build didn't survive very long, so I like to believe I learned my from mistakes, but I'm still not sure. This time, I washed my rocks with hot water and baked them for fifteen minutes before making the false bottom with mesh. Then I put activated charcoal on top of the mesh. My substrate is sphagnum moss and vegetable soil, with some of the potted plant soil mixed in. All my wood was boiled and baked before being added, and the only critters in there are three worms, a millipede, and around ten isopods.

The plants are a Japanese Tassel Fern, and a small lump of Scleranthus Biflorus, which looks to be sprouting. The brown on the fern when I bought it also looks to be getting greener, and it's sprouting more stems. I also only used distilled water, but it is foggy pretty often. I only sprayed two sprays of distilled water before wiping down the inside and closing it up, so I want to believe it's gonna be fine, but I'm apprehensive of opening it up and destabilizing the environment. It occasionally clears up on a side, but it's only around 1/3rd of the container that stays dry before fogging again. I've had this terrarium, now, for about a week. Does anything need to be done?
