What we liked
- + Tight 8 to 15 mm sizing means fewer small fragments to slip through a mesh barrier into the water reservoir.
- + Kiln-fired, inert and pH neutral according to the listing, so it does not break down or leach into standing water.
- + Porous and reusable: it can be rinsed and used again when an enclosure is rebuilt.
Trade-offs
- - Sold by volume at 5 liters, which only covers a shallow layer in a small to mid-size enclosure.
- - Marketed for hydroponics instead of terrariums, and the spec sheet says to rinse it before first use.
