When I tried to go bioactive without a drainage layer I got bugs and my plants died because of moist build up. When I gave it a drainage layer wow it impacted my enclosure and made it so no bugs and my plant flourish. ## Frequently Bought Together - Zoo Med HydroBalls Lightweight Expanded Clay Terrarium Substrate, 2.5 Pounds - Zilla Reptile Terrarium Bedding Substrate Jungle Mix, 8 Quart - Zoo Med Naturalistic Terrarium Mesh, 18 x 18-Inches --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/3577802-zoo-med-hydroballs-2-5-lbs](https://www.desertcart.be/products/3577802-zoo-med-hydroballs-2-5-lbs) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-07-24*
