The Bio Dude's handcrafted rainforest substrate retains the water your plants and humidity depend on, then drains the excess efficiently into a HydroGrow layer below instead of letting it go stagnant. It's formulated for day geckos, crested geckos, and other neo-tropical herps — the same mix our own guides spec for gargoyle and leachianus gecko builds.
