The Bio Dude Compressed Sphagnum Moss Brick — 150 g

Sphagnum moss in its most storable form: a compact 150-gram brick (140–160 g by weight) of 100% natural, long-fiber Sphagnum cristatum that expands dramatically after a ten-minute soak in warm water. Keep it in a drawer until you need it — then you have fresh moss for a humid hide, a shed box or a plant mount on demand. Your order ships direct from The Bio Dude — see our shipping policy and refund policy for how these orders work.

• The shed-season staple: damp sphagnum in an enclosed hide is the standard fix for shedding trouble — our guide to stuck shed in snakes covers exactly how to set one up.
• Winter insurance: when home heating crashes enclosure humidity, moss-packed hides restore a humid refuge fast — see our winter humidity crash guide for the full playbook.
• Ten-minute prep: soak in warm water for about 10 minutes, rinse thoroughly, then squeeze to the moisture level you want.
• 6A-grade fiber: long-fiber moss with minimal debris — a small amount of natural straw or stick fragments can appear, as with any real harvested moss.
• Beyond the hide: also suits amphibian and invertebrate setups and works as a growing medium for orchids and other plants.

The compressed format is the one to stock as a backup — it takes up almost no space until the day you actually need it.
