What to Look For
- Open vs. closed — closed for tropical/humidity lovers, open for succulents & cacti.
- Plant scale — choose slow-growing miniatures that won’t outgrow the glass.
- Drainage layer — charcoal and substrate prevent rot in a container with no holes.
- Light — bright, indirect; never bake a closed terrarium in direct sun.
Care Basics
- Closed terrariums: rarely need watering — condensation recycles moisture.
- Open terrariums: water lightly and treat like the plants inside (often succulents).
- Airflow: open a closed lid occasionally if you see heavy fog or mold.
- Trim: prune to keep plants in scale and remove anything yellowing.
Where This Connects
- Succulents — perfect for open terrarium and dish gardens
- Air Plants — soil-free plants that suit creative displays
