Planted large terrariums come in a variety of shapes and sizes, but they generally fall into three distinct categories when it comes to containers. Whether you’re looking to adapt an existing container or go the custom route, your choice will depend on your planting goals and your appetite for a creative challenge.

Bottles: The Ultimate Garden Containers

If you know where to look, you can find some truly giant bottles that are perfect for creating a stunning terrarium. Classic brewing bottles, such as carboys or demijohns, can hold over 50 liters of volume and have become a staple in the terrarium world. These oversized bottles offer a beautiful way to showcase tropical terrarium plants. However, working with a bottle does come with its limitations. Planting through a narrow opening can be tricky, especially when you can’t reach the bottom with your tools. This option is best suited for more experienced terrarium builders.

Wardian Cases: Timeless Elegance

The Wardian Case, the original terrarium, was used to transport tropical plants during the Victorian era. These elegant glass containers, reminiscent of miniature greenhouses, can be scaled up to create large terrariums. While they offer a certain degree of customization, you are still limited by the basic glass structure. However, if you’re looking to house taller plants that require ample headroom, Wardian Cases are an excellent choice.

Tanks: Versatile and Ambitious

Tanks offer a world of possibilities for large terrariums. From classic horizontal tanks to vertical cabinet-style ones, you can find a container that suits any tropical plant. With a bit of DIY creativity, you can adapt an Ikea glass cabinet or an old fish tank into the perfect terrarium. Reptile terrarium companies also offer a wide range of large tank terrariums that are versatile and adaptable. These tanks can accommodate modern technical systems such as lighting, ventilation, and even waterfalls. The spacious interior allows for elaborate custom backgrounds and hardscape arrangements, making them ideal for those with uncompromising visions.


Now that you have a better understanding of the different types of large terrariums available, it’s time to find the perfect container for your project. While it may be challenging to find unique and custom options, there are places where you can start your search.
