It combines loam topsoil and coir in a 66:34 ratio, giving you a substrate that holds moisture, supports burrowing, and doubles as a planting medium — all in one bag.\u003c\/p\u003e\u003ch3\u003eWhat's in the Mix\u003c\/h3\u003e\u003cp\u003eThe base is 66% loam topsoil, chosen for its structure and natural feel underfoot. The remaining 34% is coir, which improves water retention and softens the substrate enough to allow tortoises to burrow naturally. No mineral grit is included — a deliberate decision for those who prefer to remove that variable from their husbandry.\u003c\/p\u003e\u003ch3\u003eImpaction and Grit-Free Keeping\u003c\/h3\u003e\u003cp\u003eImpaction is widely considered a husbandry issue, but some keepers prefer to avoid limestone grit entirely as a precaution. PR Tortoise Life BIO is formulated with that in mind, offering a loam-and-coir blend that supports healthy keeping without introducing grit into the enclosure.\u003c\/p\u003e\u003ch3\u003eBioactive Compatibility\u003c\/h3\u003e\u003cp\u003eThis substrate is well-suited to bioactive tortoise setups. It works as a planting medium, supporting live plants directly in the enclosure. Mixing in tortoise-appropriate seeds creates natural foraging opportunities, and adding a clean-up crew of isopods suited to Mediterranean conditions completes a functional bioactive system.\u003c\/p\u003e\u003ch3\u003eMoisture Retention and Burrowing\u003c\/h3\u003e\u003cp\u003eThe coir content plays a practical role in day-to-day keeping — it holds moisture in a way that loam alone does not, which helps maintain the humidity gradient many tortoise species benefit from. The texture also allows tortoises to dig and burrow, a behaviour that should always be accommodated in captive environments.\u003c\/p\u003e\u003cp\u003eWhether you're building a bioactive setup from scratch or simply looking for a grit-free substrate with good structure, PR Tortoise Life BIO gives you a reliable foundation that works with the animal's natural behaviours rather than against them.\u003c\/p\u003e","brand":"Peregrine","offers":[{"title":"Default Title","offer_id":54148620878161,"sku":"SMT020","price":9.58,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0963\/0403\/8225\/files\/SMT020_1.jpg?v=1782599882","url":"https:\/\/viperia.co.uk\/products\/pr-tortoise-life-bio-10-litre","provider":"Viperia UK","version":"1.0","type":"link"}
