ProRep Forest Moss Brick 100g | Vivarium Humidity Moss

The PR Forest Moss Brick is a compressed, expandable natural moss substrate additive designed to raise humidity and retain moisture in reptile and amphibian enclosures. Sourced from sustainable cultivation and completely chemical-free, it expands to approximately 5 litres once rehydrated — making it a practical and visually attractive addition to any bioactive or naturalistic terrarium setup.

Humidity and Moisture Retention

Forest moss is one of the most effective natural materials for drawing in and holding moisture within an enclosure. It can be used on its own as a moist hide substrate or blended with coco husk or bark chip bedding to extend the humidity-retaining properties of those substrates. Keep it hydrated and away from direct heat sources to maintain its condition and effectiveness.

Shedding Support

A damp moss layer is particularly beneficial for species that require elevated localised humidity during a shed cycle. Leopard geckos and royal pythons are two of the most common species kept in the UK that benefit from a humid moss hide, helping them shed cleanly without retained skin.

Appearance in the Vivarium

Once rehydrated, this moss has a natural, lush appearance that complements planted or decorated terrariums. It integrates well with naturalistic décor, live or artificial plants, and cork or wood features, contributing to an enclosure that looks as good as it functions.

Sourcing and Safety

• Cultivated from sustainable sources — not wild-harvested
• Chemical-free, with no added fertilisers, pesticides, or preservatives
• Safe for use with reptiles, amphibians, and invertebrates

A straightforward, reliable substrate additive that covers the basics well — humidity management, shed support, and natural aesthetics — in a compact, easy-to-store brick format.
