Closed or open terrarium: which one to choose depending on your plants?

Dreaming of creating a lush, soothing ecosystem in your home? A terrarium is the ideal solution for bringing nature indoors. But between a closed and an open terrarium, how do you choose? Discover the pros and cons of each type to find the one that best suits your plants.

The closed terrarium, a self-regulating mini-ecosystem

The closed terrarium is a veritable little world unto itself. Thanks to a water recycling system, it is completely self-contained and regulates itself naturally. The water evaporates, condenses on the walls, and falls back to the ground, creating a perpetual cycle. This helps maintain an ideal humidity level for plant growth.

The main advantage of a closed terrarium is that it requires very little maintenance. Once installed, simply place it in a bright location and water it occasionally. The plants draw the water and nutrients they need directly from the soil, without any intervention on your part. This makes it a perfect solution for people who don't have much time to devote to their plants.

Additionally, the closed terrarium provides a protected environment, protected from temperature fluctuations, humidity, and light. This is ideal for tropical or rain-loving plants that require a stable, humid climate to thrive.

However, the closed terrarium also has some drawbacks. Since it is completely airtight, it doesn't allow for easy ventilation. This can be problematic for certain plants that require regular air exchange. You also need to be careful not to overwater, as this can create harmful excess humidity.

The open terrarium, more freedom for plants

Unlike a closed terrarium, an open terrarium is not airtight. It allows air and gas exchange with the outside world. This allows for better ventilation, ideal for plants that need to breathe.

The open terrarium also offers more flexibility in watering management. Since there's no closed water cycle, you can easily adjust the amount of water according to your plants' needs. This is a significant advantage, especially for species that fear excess humidity.

Additionally, an open terrarium gives you more freedom in choosing plants. You can plant a wider variety of plants, including those that aren't suitable for a closed terrarium. It's the perfect option for creating a truly small indoor garden.

However, an open terrarium requires more regular maintenance. You'll need to water more frequently and ensure proper temperature and humidity conditions are maintained. It's also more sensitive to environmental changes, which can weaken some plants.

Choosing your terrarium according to your plants

So, closed or open terrarium? The choice depends primarily on the plants you want to keep inside. Some species, like ferns or orchids, prefer a humid and stable environment in a closed terrarium. Others, like succulents or succulents, will thrive in an open terrarium with better ventilation.

Don't hesitate to inquire about the specific needs of your plants before making your choice. You can also mix the two types of terrarium to create a harmonious and diverse ensemble.

Whatever your choice, remember that a terrarium is a fragile ecosystem that requires a little attention. With the right care, it will quickly become your own personalized, soothing, and restorative corner of nature.
