What Is a Closed Terrarium?

A closed terrarium is an enclosed environment used to grow plants indoors. This type of terrarium provides a humid, warm, and controlled atmosphere, making it ideal for growing plants that cannot tolerate drastic changes in temperature or humidity levels.

The container should be sealed tightly with either glass or plastic, ensuring the right conditions are met inside the terrarium.

If you are relatively new to terrariums, you might be tempted to think that closed and open terrariums are the same. However, this is not the case.

  • Thrive in humidity and warmth – The environment inside your terrarium should be warm and humid, so pick plants adapted to such conditions.
  • Survive with minimal airflow – Typically, a closed terrarium does not have much airflow, so make sure the plants you choose can survive with minimal air circulation.
