{"product_id":"pr-leaf-litter-block-2-5kg","title":"ProRep Leaf Litter Block 2.5kg – Bioactive Vivarium Substrate","description":"\u003cp\u003eThe PR Leaf Litter Block is a compressed brick of broken leaf litter designed to recreate the layered forest floor environment essential to bioactive vivariums. Expanding from a single block into a substantial volume of natural material, it gives keepers a practical way to introduce authentic leaf litter to tropical and woodland setups without sourcing loose material in bulk.\u003c\/p\u003e\u003ch3\u003eWhy Leaf Litter Matters in a Bioactive Setup\u003c\/h3\u003e\u003cp\u003eLeaf litter is far more than aesthetic. In forest and jungle environments, accumulated fallen leaves form a microhabitat in their own right — sheltering reptiles, amphibians, and insects, buffering against temperature and humidity fluctuations, and providing a constant food source for detritivores. Replicating this layer in a vivarium supports natural behaviours including burrowing, foraging, and hiding.\u003c\/p\u003e\u003ch3\u003eSupporting Your Cleanup Crew\u003c\/h3\u003e\u003cp\u003eAs leaf litter decomposes, it feeds the microfauna that keep a bioactive enclosure functioning — springtails, woodlice, and millipedes all rely on decomposing organic matter as a primary food source and shelter. Without sufficient leaf litter, these detritivore populations struggle to establish and maintain themselves, which undermines the entire bioactive system.\u003c\/p\u003e\u003ch3\u003eSoil Enrichment and Plant Growth\u003c\/h3\u003e\u003cp\u003eBeyond fauna, decomposing leaves release nutrients back into the substrate layer, supporting the root systems of living plants within the enclosure. This gradual nutrient cycling mirrors what happens naturally on a forest floor and reduces the need for manual intervention over time.\u003c\/p\u003e\u003ch3\u003eHow to Use\u003c\/h3\u003e\u003cp\u003eThe PR Leaf Litter Block works best when incorporated alongside soil-based substrates and larger whole leaf litter pieces, building up the distinct layers characteristic of forest floor habitats. It is suitable for tropical, subtropical, and woodland bioactive builds housing reptiles and amphibians.\u003c\/p\u003e\u003cp\u003eFor keepers investing in a genuinely functional bioactive enclosure, establishing the leaf litter layer correctly from the outset makes a measurable difference to the long-term health and stability of the entire ecosystem.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54148639424849,"sku":"SPC855","price":14.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/SPC855_1.jpg?v=1782600173","url":"https:\/\/viperia.co.uk\/products\/pr-leaf-litter-block-2-5kg","provider":"Viperia UK","version":"1.0","type":"link"}
