Whether you’re a beginner or an experienced terrarium enthusiast, these tips will help you select the perfect container for your miniature garden. Use your terrarium containers to create unique and beautiful indoor gardens.
Best Material for Terrarium Containers
The ideal material for a terrarium container is glass. Apothecary jars are a popular choice for terrarium containers due to their glass material and variety of sizes and styles. While plastic containers can work, glass is preferable due to its durability and clarity. Glass containers provide a clear view and maintain the moisture levels necessary for a thriving terrarium.

Effective Sealing Options
Avoid using wood for sealing as it can introduce mold and deteriorate over time. Cork is a better, mold-resistant choice, providing a tight seal without compromising the ecosystem. Rubber or sponge can also be used to seal the terrarium opening effectively.

Light Requirements
Closed terrariums need adequate light to support plant growth, so choose a jar that allows light to pass through without obstruction. Clear glass is ideal for growth, ensuring that your plants receive the necessary light. Colored glass, while aesthetically pleasing, might hinder light penetration and affect plant health.
Pro Tip: Color of Glass
For a standard growing terrarium, clear glass is ideal. In my experience, while colored glass containers can work, they may not be as effective. I used a colored glass container, and although my terrarium didn't die, it also didn't thrive. Feel free to experiment with colored glass, but be aware that it might impact the growth of your plants.

Checking for Leakage
Test the container for leaks by filling it with water before use. A leaking container indicates it's not airtight, making it unsuitable for a closed terrarium. Ensuring your container is leak-proof is essential for maintaining a stable environment inside.
Size Considerations
While size does matter, it’s more about ease of use. Different sizes of containers can accommodate various types of foliage plants, making it easier to create a beautiful arrangement. Smaller jars are trickier to work with due to limited space for arranging plants and decorations. Larger containers are more forgiving, offering ample space for plant growth and adjustments. Medium-sized containers are great for beginners, balancing ease of use and aesthetic appeal.
Unique Terrarium Containers
Consider unique containers like terrarium lamps for dual functionality as decoration. Open terrariums are also a great option for tropical plants and provide endless possibilities for plant arrangements. These creative options can add a unique touch to your home décor while housing a thriving ecosystem. The versatility of terrarium lamps makes them an excellent choice for both functionality and style.

I collect unique glass terrarium containers from Goodwill, which is great for second hand original glass containers and other stores like Ross, Marshalls, and TjMax.

Using Wine Bottles
White wine bottles, with their clear glass, can be used as terrarium jars, offering an elegant and stylish option. However, red wine bottles are more challenging due to their darker glass, which can limit light penetration. If you prefer using wine bottles, opt for those with clear glass for the best results.
