To maintain your terrarium and ensure its longevity, it is important to follow these key steps:

1. Light: Place your terrarium in a location with indirect sunlight or in a dark room. Avoid placing it in direct sunlight, as this can cause the plants to "burn". Use a LED lamp to light up your terrarium as its source of energy. Turn on your lamp on for 6-8 hours per day for optimal results

2. Watering: Monitor the moisture level in your terrarium. Water sparingly, only when the soil appears dry. Overwatering can lead to root rot and other issues. 

3. Ventilation: While terrariums are enclosed ecosystems, it is important to provide some ventilation by occasionally opening the lid or removing it for a short period to prevent mold and excess moisture buildup.

4. Pruning: Trim any dead or overgrown plant material to maintain the health and aesthetics of your terrarium.

5. Cleaning: Wipe the glass walls of your terrarium with a soft cloth to remove any dust or water spots that may obstruct light.

By following these maintenance tips, you can enjoy a thriving and beautiful terrarium for years to come.
