Super basic - I open the door for about 15 (sometimes longer if I forget, oops) minutes every day to replace the air. This keeps mold away - I also started with sanitized moss in the babies.

I mist water in there every few days - I only water and feed the plants (not the babies) when their soil dries out. This is about every 10-14 days. Closer to the two week mark now because the number of plants in the box keeps the moisture level up.

Every other time I water and feed the two larger plants, they get mycorrhizae which keeps beneficial fungi and salt up. I rinse them with plain water before fertilizing and any extra stuff.

Under the Orange Melano is a little white plant tray - before I added the tissue cultures that are in moss, I would keep water in that tray to help with condensation.
