ProRep Crestie Life Substrate 10 Litre | Crested Gecko Vivarium Soil

The PR Crestie Life Substrate is a purpose-blended terrarium substrate designed specifically for crested geckos and other arboreal species that depend on sustained high humidity. This is not a general-purpose mix — every ingredient has been chosen with the needs of moisture-loving, tree-dwelling reptiles in mind.

Specially Formulated Blend

Rather than repurposing a generic soil mix, this substrate has been blended from high-quality ingredients to match the specific environmental requirements of crested geckos and comparable arboreal species. The result is an open-structured mix that avoids compaction while retaining the moisture levels these animals need.

Humidity Retention

The substrate is engineered to absorb moisture and release it gradually, helping to sustain the elevated ambient humidity that crested geckos require without the keeper needing to mist constantly. This slow-release characteristic makes it particularly well-suited to bioactive or naturalistic vivarium setups where stable conditions matter.

Slightly Acidic pH

The mix is formulated with a slightly acidic pH, which serves a practical purpose beyond plant health — it actively inhibits excessive bacterial growth within the substrate. This helps keep the vivarium environment cleaner and more stable over time, reducing the risk of harmful microbial build-up in a humid enclosure.

Bioactive and Planted Vivarium Compatible

The open structure and nutrient-supportive composition of this substrate allow live plants to establish and thrive, making it an excellent base layer for keepers building bioactive or heavily planted enclosures. Creating a naturalistic environment for crested geckos is straightforward with a substrate that supports both the animals and the plant life alongside them.

At 10 litres, the PR Crestie Life Substrate provides a practical volume for setting up or refreshing a crested gecko vivarium, giving keepers a reliable, species-matched foundation to build on.
