ShroomRoom MossBase - Moss Adhesion Layer

ShroomRoom MossBase is a hydrophilic moss adhesion layer designed to help moss spores, fragments, and slurry mixes establish on vertical and textured terrarium surfaces. Its moisture-retentive formula creates a tacky biological layer that improves spore contact, reduces runoff, and promotes even moss establishment across backgrounds made with SR TropicalClay, GeoForm Clay, cork bark, wood, and other hardscape surfaces.

MossBase is ideal for creating lightweight moss walls, naturalistic living surfaces, and biologically active backgrounds in terrariums, vivariums, and paludariums. Its mud-like consistency spreads easily while remaining breathable and re-wettable, making it an excellent companion for moss propagation systems. The product is designed specifically for use underneath moss inoculants and moss blends rather than as a structural hardscape material. TropicalClay is to be used first, then MossBase, then MossMix.

Directions:

Slowly add water while mixing until a thick, tacky mud consistency is achieved

Allow mixture to hydrate for 2–5 minutes before use

Apply a thin layer (only need 1-3mm) across where you intend to use BryoSpore, dehydrated BryoBrick, or SR MossMix. 

Target Texture:

Tacky

Spreadable

Matte, not glossy

Thick enough to stay in place without dripping

Maintain consistent humidity during moss establishment and avoid heavy direct spraying immediately after application. We recommend 90% glass, 10% screen to achieve 85-95% humidity.
