light stress on Terrarium
Quick answer
If your Terrarium has light stress, the most likely cause is: Glass containers create greenhouse effect amplifying sunlight 3-5x. Direct sun through glass raises internal temperature to 140F (60C) within 30-60 minutes, causing protein denaturation and cell death in plant tissues
Start here:
- 1. Place terrariums in bright indirect light - near north or east-facing windows
- 2. Avoid south and west windows with direct afternoon sunlight
