Closed terrariums are miniature gardens that thrive in their own self-sustaining ecosystems. Whether you’re a seasoned plant enthusiast or just getting started, creating your own closed terrarium is a rewarding project that doubles as stunning decor. The good news? You don’t have to be a master gardener to build one! With the right kit and a few tips, anyone can craft a gorgeous, low-maintenance terrarium. Here’s everything you need to know about DIY closed terrarium kits and how to make the process as simple as possible.
What is a Closed Terrarium?
A closed terrarium is a sealed glass container that houses plants, creating a mini greenhouse effect. The lid traps moisture inside, which continuously cycles through condensation and evaporation. This unique feature means closed terrariums require minimal watering and care—perfect for anyone who loves plants but has a busy schedule.
Why Use a DIY Closed Terrarium Kit?
Building a closed terrarium from scratch might seem daunting, but that’s where DIY kits come in. A terrarium kit provides all the essentials you need in one package. No hunting through garden centres or wondering if you’re missing a crucial component.
Here are some benefits of using a terrarium kit:
-
Convenience: Everything you need, from the container to the substrate, is included.
-
Guidance: Kits often come with instructions, making them beginner-friendly.
-
Consistency: Pre-measured materials ensure you’ll have enough to complete your project.

Why Closed Terrariums Fail (and How to Avoid It)
While closed terrariums are low-maintenance, they’re not entirely foolproof. Here are common pitfalls and how to troubleshoot them:
-
Too Much Water: Overwatering can lead to mold and root rot. Use a spray bottle to lightly mist instead of soaking.
-
Wrong Plants: Not all plants thrive in a closed environment. Stick to ferns, mosses, and tropical species.
-
Too Much Light: Direct sunlight can turn your terrarium into a sauna. Keep it in bright but indirect light.

FAQ: DIY Closed Terrariums
1. Do closed terrariums need sunlight? Yes, but indirect light is best. Too much direct sunlight can overheat the terrarium and harm the plants.

3. Can I use any plant in a closed terrarium? No, it’s important to use plants that thrive in high humidity, like moss, ferns, and tropical plants. Check out this list of top plants for ideas.
4. Why is there mold in my terrarium? Mold usually appears due to excess moisture or lack of airflow. Open the lid temporarily to let it dry out or use a cotton swab to remove the mold.
5. Where can I buy a closed terrarium kit? You can find high-quality kits at Terrarium Kits.
With the right tools and a little creativity, you’re well on your way to building a beautiful closed terrarium. Happy planting!
