Have you ever wished for a tropical paradise experience without having to fly to the other side of the world? Well, you can create that easily at home (well.. kind of). Enter the closed plant terrarium, a self-sustaining, airtight jar that turns small plants into big stars of a tropical microclimate. Think of it as your personal rainforest in miniature, requiring minimal maintenance and offering maximum botanical charm.
A Tiny Jungle Without Lizards (Or Hassle)
Let’s clear one thing up: this is not a vivarium. No lizards, no frogs—just plants doing their thing. A closed plant terrarium is the perfect solution for plant lovers who crave a lush, humid environment without the drama of frequent watering. (and very little fertilisation). The secret sauce? Light, which powers everything from the water cycle to photosynthesis.
The Science of Self-Sufficiency
Here’s where things get fascinating (and surprisingly simple). Your terrarium is a mini-lab of natural processes that keep your plants thriving with barely a drop of effort from you. You basically mimic a real life climate into a glass jar.
The Water Cycle: Tiny Rainforest Magic
- Sunlight warms the glass jar, raising the internal temperature.
- The plants “sweat” (a.k.a. transpire), releasing water vapor.
- This vapor condenses on the cooler walls, forming droplets that drip back into the soil.
- The roots slurp it up, completing the cycle.
Photosynthesis: The Plant's Power Source
- Light helps the plants absorb water and nutrients through their roots.
- The plants capture carbon dioxide (CO₂) from the air and use it to produce oxygen and energy-rich sugars.
- Bonus: Your plants repay you by refreshing the air inside the terrarium!
This means your plants are essentially running their own eco-friendly hydration and energy systems.
Humidity Levels: Welcome to the Tropics
Humidity, or “hygrometry”, is what makes closed terrariums so special. These glass-bound ecosystems boast nearly 100% humidity—a stark contrast to your home’s typical 30%. While most houseplants dream of 70% humidity, your terrarium plants live the lush life, thriving in their steamy sanctuary.
Why You Need a Closed Plant Terrarium
Still on the fence? Let’s paint the picture:
- Low Maintenance: With its self-sustaining water cycle, this is the ultimate set-it-and-forget-it plant care. Although it is super fun to create your terrarium, and once in a while, you do need to re-decorate it or cut some plants since they will just grow and grow in this optimal climate.
- Exotic Appeal: A closed terrarium is like having a slice of the rainforest in your living room. And it is so fun to watch it grow.
- Eco-Friendly: No plastic bottles or high-tech gadgets—just light, glass, and the magic of nature. But how to set it up?
How to Get Started
Creating your terrarium is as simple as choosing the right plants (ferns and mosses love this environment), finding a clear, sealable jar, and setting it up in a spot with bright, indirect light. Water it slightly in the beginning and we always add some drops of SuperVit in the soil, just to kick-start the climate with vitamins and amino-acids. Then, sit back and watch nature do its thing.
Conclusion
A closed plant terrarium is more than just a home for plants—it’s a glimpse into the fascinating balance of natural ecosystems. Whether you’re an experienced green thumb or a newbie to indoor gardening, it’s a fun, low-maintenance way to bring the beauty of the tropics into your home. Plus, it’s sure to spark conversations and maybe even a few laughs—because who wouldn’t love a rainforest in a jar?
