1. Mesh or Screen:
- Plastic or metal mesh with small holes (1/4 inch to 1/2 inch) can be placed at the bottom of the terrarium to provide drainage.
- It allows excess water to escape while preventing the soil from seeping out.
- Mesh also helps with aeration and avoids waterlogged conditions.
2. Egg Crate or Plastic Netting:
- Egg crate flats or plastic netting can be cut to fit the base of the terrarium.
- They provide good drainage and allow air to circulate around the roots of plants.
- The raised surface helps prevent the soil from becoming compacted.
3. Pebbles or Gravel:
- A layer of small pebbles or aquarium gravel can be used as a false bottom.
- Pebbles allow water to drain freely while providing aeration.
- They also add weight to the terrarium, making it more stable.
4. Charcoal:
- Activated charcoal can be used as a false bottom material to improve drainage and purify the water.
- It helps remove impurities, toxins, and odors from the terrarium.
5. LECA Pebbles (Lightweight Expanded Clay Aggregate):
- LECA pebbles are lightweight, porous clay pebbles that are commonly used in hydroponics.
- They provide excellent drainage and aeration, and can also help retain moisture in the terrarium.
6. Cork Bark or Coco Fiber:
- Natural materials like cork bark or coco fiber can be used to create a false bottom.
- They are organic and aesthetically pleasing, providing drainage and preventing soil compaction.
7. Styrofoam:
- Styrofoam pieces can be used to create a lightweight false bottom.
- They provide drainage and help distribute moisture evenly.
8. Hydroton or Seramis Granules:
- Hydroton or Seramis are inorganic clay granules used in hydroponic gardening.
- They are lightweight and porous, offering excellent drainage and aeration.
When creating a false bottom, ensure it covers the entire base of the terrarium to facilitate proper drainage. Add enough substrate or soil on top of the false bottom to provide sufficient rooting space for the plants.
