Perfect for small setups, rehousing jobs, or when you just need a handy amount of substrate without opening a massive block. This compact coco fibre disk expands with water to give you a practical, easy-to-use substrate that works well for spider tubs, sling enclosures and other small invertebrate setups.
 
It’s a great option for keepers housing just a couple of spiders, topping up an enclosure, or keeping spare substrate on hand for quick clean-outs and rehousing. Just add water and allow it to expand before use. The original product is sold as a small coco fibre block that expands with about 330ml of water into roughly 1 litre of substrate.
 
Coco fibre is popular for helping create a natural-looking base layer and can be used in a variety of setups depending on the species being kept. Always make sure the substrate is prepared appropriately for your animal’s humidity needs and enclosure style.
