HydroGrow V2 is The Bio Dude's terrarium drainage layer — 100% natural clay that captures excess water out of the bioactive substrate above while aerating top to bottom, preventing the anaerobic water pockets that make tropical enclosures go sour. It's the base layer under Bio Dude's own Terra Flora and Terra Fauna tropical substrates — if you're building a dart frog, tree frog, or planted gecko vivarium, this is the layer that goes in first.
