Maintenance & Troubleshooting

Pruning, watering cycles, and dealing with mold and pests.

The First Two Weeks

The first 14 days are critical. Observe the glass every morning and evening.

  • Foggy all day? Too much moisture. Open the lid for 12 hours.
  • No condensation at all? Too dry. Give it a few sprays of distilled water.
  • Light condensation morning/evening, clear during the day? Perfect balance.

The Cleanup Crew: Springtails

If you haven't already, introduce springtails (Collembola). These tiny, white micro-arthropods eat mold, decaying plant matter, and fungi. They are the essential janitors of a closed ecosystem and will prevent catastrophic mold blooms.

Pruning

In a healthy terrarium, plants will eventually outgrow their space. Use long, sterilized scissors to trim back overgrowth. This encourages bushier, denser growth rather than tall, leggy stems.

Troubleshooting Quick Guide

  • White fuzzy mold: Normal in new builds. Springtails will eat it.
  • Yellowing leaves: Often a sign of overwatering or root rot.
  • Brown, crispy leaves: Underwatering or sunburn from direct light.

Your terrarium is a living, breathing art piece. Observe, tweak gently, and enjoy the calm.
