Bioactive Terrarium Substrate Barrier Mesh (1m × 1.5m)

A long-lasting bioactive terrarium begins with proper soil layering. This durable fiberglass substrate barrier creates a clean, reliable separation between your drainage layer (false bottom) and your bioactive soil mix, preventing substrate compaction, waterlogged roots, and anaerobic bacteria buildup.

Key Benefits

• Optimized Drainage Flow: The fine-weave mesh allows excess water to drain smoothly into the false bottom while keeping substrate, charcoal, and organic matter contained in the upper layers.
• Rot & Humidity Resistant: Constructed from non-reactive, coated fiberglass that will not rust, decay, or mold in high-humidity tropical vivariums or arid setups.
• Safe for Microfauna & Inhabitants: Safe for clean-up crews (isopods, springtails), plant roots, and digging reptiles, amphibians, or invertebrates.
• Custom Sizable: Easily trims to exact enclosure dimensions with standard household scissors without unravelling.

Product Specifications

• Dimensions: 1 meter × 1.5 meters (approx. 39.4" × 59")
• Material: Coated, non-toxic fiberglass
• Color: Charcoal Black (blends discreetly along terrarium walls)
• Compatibility: Suitable for glass terrariums, wooden vivariums, paludariums, and customized display habitats

How to Install

1. Add your chosen drainage media (clay hydro-balls, pumice, or lava rock) to the bottom of the enclosure.
2. Measure your enclosure footprint and cut the mesh with standard scissors, leaving a 0.5-inch border on all sides to curl up against the glass.
3. Lay the barrier flat across the drainage layer.
4. Add your bioactive substrate directly on top, plant your greenery, and introduce your clean-up crew.
