spiderweb looking mold on rock layer?
i built my terrarium in a jug about 2 months ago. My layers consist of rocks, charcoal, moss, dirt/sand mixture, plants and moss on top.
I noticed a few weeks ago that now there is white spiderweb looking mold on the rocks layer only. I have monitored it and it does not seem to be surfacing to the plants and the plants are doing fine on top. I have only watered it once (the initial watering) and alternate window time with no window time. any ideas on what to do here? I quarantined the moss and plants before planting so I know nothing on the plants can be causing this. I am just confused why it chose that layer to grow and if anyone knows if this might surface or if they can all live happily in there?
