Problem SignsTable
Common issues and fixes.
| Sign | Cause | Fix |
|---|---|---|
| Fog 24/7 | Overwater | Open lid |
| Brown moss | Dry/light | Mist/shade |
| White fuzz | Mold | Air out |
Mold Response
Remove affected material — do not spray fungicide in enclosed habitat with animals.
Tool Sterilization
Wipe pruners with alcohol between terrariums to stop pest spread.
Glass Breakage
Replace cracked jars immediately — stress points fail under temperature change.
Safety Notes
- Wash hands after maintenance on bioactive enclosures.
- Unplug grow lights before reaching into lit terrarium.
