Step 2: Create the Base Layer
The first layer of your terrarium is crucial for drainage and overall health of the plants. Follow these steps to create the base:
- Pour a layer of gravel into the bottom of the jar, about 1-2 inches deep.
- Next, add a thin layer of activated charcoal if desired to help filter the air and prevent odors.
- Finally, add a layer of potting soil on top of the gravel, approximately 2-3 inches deep.
Pro Tip: Use a spoon to help guide the soil and gravel into the corners of the container. Why this matters: Proper layering prevents water from pooling at the bottom, which can lead to root rot.
Estimated time: 30 minutes.

FAQs
What if I don’t have a glass container? You can use any clear container, like a plastic or acrylic box, as long as it allows light in.
How long should I wait before watering? Wait at least two weeks after setting up your terrarium before adding more water.
Is it safe to place the terrarium on a windowsill? Only if it gets indirect sunlight; direct sunlight can overheat the plants.
What if my plants start to die? Check for overwatering or insufficient light. Adjust conditions as necessary.
Can I use flowers in the terrarium? It’s best to use long-lasting plants; cut flowers will wilt quickly in a closed environment.
