Are there certain plants that thrive better in closed terrariums versus open-air terrariums?

When it comes to terrariums, there are two main types: closed terrariums and open-air terrariums. Both have their advantages and disadvantages, but one common question that arises is whether certain plants thrive better in closed terrariums or open-air terrariums. In this article, we will explore this topic in detail.

Terrariums and Indoor Gardening

Terrariums are miniature ecosystems that can be created indoors, allowing you to grow plants in a controlled environment. They are popular among indoor gardening enthusiasts as they provide a unique way to display and care for plants.

Closed Terrariums

Closed terrariums, as the name suggests, are sealed environments. They create a self-sustainable system where the moisture in the terrarium is recycled. The moisture evaporates, condenses on the walls, and then drips back onto the plants, creating a cycle. This makes closed terrariums highly efficient in terms of water usage as they require less frequent watering.

Because of their sealed nature, closed terrariums have high humidity levels, resembling a tropical environment. These conditions are ideal for plants that thrive in moist and humid environments, such as ferns, mosses, and certain tropical plants.

The high humidity in closed terrariums also helps in retaining moisture, reducing the risk of drought or dehydration for plants. It creates a microclimate that is self-regulating, making it suitable for plants that are more sensitive to fluctuations in moisture levels.

Open-Air Terrariums

Unlike closed terrariums, open-air terrariums do not have a sealed environment. This means that the moisture in an open-air terrarium is not recycled and needs to be replenished regularly through watering.

Open-air terrariums mimic the natural outdoor environment with normal air circulation. These terrariums provide better ventilation and are suitable for plants that thrive in drier conditions. Succulents, cacti, and air plants are examples of plants that do well in open-air terrariums.

Since open-air terrariums do not trap moisture like closed terrariums, they are less prone to issues such as fungal growth or mold. However, their open nature also means that they require more regular monitoring and maintenance to ensure appropriate watering levels.

Choosing the Right Plants for Your Terrarium

When selecting plants for your terrarium, it is essential to consider their specific needs and the type of terrarium you have.

  • In closed terrariums, choose plants that prefer high humidity and low light conditions. Ferns, mosses, Fittonia, and air plants are good options.
  • In open-air terrariums, select plants that can tolerate drier conditions and good air circulation. Succulents, cacti, and air plants are suitable choices.

Additionally, consider the size of your terrarium and the growth habit of the plants. Avoid selecting plants that will outgrow the terrarium quickly and overcrowd the space.

Summary

In conclusion, the type of terrarium you have—closed or open-air—greatly influences the type of plants that will thrive in it. Closed terrariums are suited for plants that enjoy high humidity and moist conditions, while open-air terrariums are better for plants that prefer drier environments. It's important to choose plants that are well-matched to the specific conditions of your terrarium for successful indoor gardening. Remember to regularly monitor and care for your terrarium to maintain the health and beauty of your plants.
