Why Terrariums Are Poor Choices for Carnivorous Plants

Major Drawbacks of Terrariums

• Promote fungal and bacterial infections due to stagnant, humid conditions.
• Light-loving plants (e.g., Venus flytraps) thrive better in open air, even under artificial light.
• Enclosed terrariums in sunlight can overheat rapidly, killing plants and damaging roots.

Humidity Misconceptions

Most carnivorous plants adapt well to low humidity; high humidity is rarely mandatory.

If You Must Use a Terrarium

• Ensure drainage holes or regularly refresh water.
• Use airy, granular mix: 50% perlite or silica sand, 50% sphagnum peat or desalinated coir.
