A terrarium is an enclosed space for plants, moss or small display scenes, and some are built to house small animals. We have not used these products ourselves, so this guide does not rank anything. It describes features and construction so you can compare enclosures for your home.
Begin with what will live or grow inside. Plants and moss need light and moisture control, while animals need space, ventilation and a design suited to the species, so read the care guidance for your chosen species. Compare the size, the height, the glass thickness and the lid style. Think about whether you want a front-opening door for easy access or a top lid for easy watering. Also check where the terrarium will sit, since window sun and heat can change conditions inside. Read each listing for the stated glass thickness, the lid fittings and the base build, and keep in mind that a tall enclosure is heavier and needs a firmer stand.

What to Look For
| Factor | Why it matters | What to check |
|---|---|---|
| Size and height | Space shapes what you can plant or keep inside. | Compare the dimensions with your plans and your shelf. |
| Glass or plastic | Glass gives clear views, while plastic is lighter. | Read the material and the thickness in the description. |
| Ventilation | Airflow affects moisture and the type of plants you can grow. | Check for mesh panels, vents or an adjustable lid. |
| Access | Doors and lids affect how easily you tend the space. | Look for a front door, top lid and any locking latch. |
| Lighting and heating options | Many setups need added light or warmth. | See whether fittings are included or can be added. |
| Base and drainage | A waterproof base helps keep soil and water contained. | Check the base build and any drain or tray. |
Setup and Care Tips
- Place the terrarium on a level, sturdy surface that can carry the full weight.
- Build the base with layers such as drainage stones, a barrier and soil as the plants need.
- Choose plants that suit the light and humidity in your home.
- Keep the enclosure out of strong direct sun, which can overheat the glass.
- Wipe the inside and outside of the glass with a soft cloth and mild cleaner.
Mistakes to Avoid
- Buying an enclosure without researching what you will place inside.
- Overwatering plants in a closed space.
- Ignoring ventilation needs.
- Putting the terrarium on a weak shelf.
- Using harsh cleaning sprays that leave residue.
FAQ
Open or closed terrarium?
Closed designs hold moisture and suit ferns and moss, while open ones suit plants that like drier air, such as succulents. Choose the style that fits your plants.
Do I need special soil?
Different plants prefer different mixes, so match the soil to your plants and follow the maker’s or grower’s advice.
The Short Version
Plan what goes inside first, then choose size, ventilation and access to match. Place the terrarium on a firm surface with suitable light. An enclosure that suits your plants and your room will be easier to enjoy than one chosen on looks alone, so compare the full description of each model.
