Repashy SuperHatch Our SuperHatch is an Advanced Incubation Medium that allows for easy Moisture Monitoring (it Changes Color) and is Indefinitely Reusable. Great for Gecko Eggs. INFORMATION: This is a course grade ceramic product (Calcined Clay). It has excellent porosity and is the next generation in egg incubation media. It does not break apart over time, does not compact, or float. Its color changes based on the amount of water it contains so you can easily monitor visually for changes in moisture level. It can be re-used indefinitely by cooking or boiling to sterilize. SuperHatch has extreme porosity combined with very fine internal structure size. This allows SuperHatch to absorb and hold large amounts of water, with a very slow rate of evaporation. This helps control the quick release of water which causes surface moisture and condensation. Ingredients: 100% Arcillite.
