The ProRep Sphagnum Moss Brick is a compressed, expandable moss substrate used by reptile keepers to manage humidity in vivariums, shedding boxes, hides, and egg incubation setups. A single 100g brick expands to yield up to 5 litres of usable moss.
What It's Used For
Sphagnum moss is a reliable tool for creating moist microenvironments within an enclosure. It is well suited to humid hides for leopard geckos and royal pythons during shed cycles, and works equally well as a moisture-retaining layer in egg boxes during incubation.
Mixing With Other Substrates
The moss can be combined with coco husk or bark chip bedding to extend moisture retention across the enclosure floor. This makes it a practical addition to humidity-dependent setups without requiring a full substrate change.
Sourcing and Safety
ProRep sphagnum moss is cultivated from sustainable sources and is free from chemicals, making it safe for direct contact with reptiles and amphibians. No preparation other than rehydration is required before use.
A straightforward, keeper-proven product that earns a permanent place in any reptile room — particularly for those keeping species with demanding shed or humidity requirements.
