4 Things Slowly Drying Out Your Terrarium Right Now!

A cabinet terrarium fails differently from a sealed jar — the air volume is larger, the failure points are less obvious, and the drying happens at the margins before you can see it from across the room. After 19 years maintaining moss in a Kyoto temple garden and three years running this specific cabinet, I found four things responsible for most humidity loss in closed cabinet systems: the door corner seal, a ventilation port designed for the wrong enclosure, insufficient substrate depth, and grow light placement creating a heat stratification zone. Each one is fixable. None require specialist products.

Results vary by species, cabinet size, and environment. These are methods from my own practice — check your own conditions before making changes.
