Wholesale CORK GRANULES | Soil Topper & Terrarium Pebbles 1000 ml

Generosa Soil Topper is a high-performance, 100% natural mulch and substrate component designed for the modern plant lover. Originally crafted as a protective topper for houseplants, these 3-8 mm cork pebbles are now a favourite in the terrarium and bioactive communities. Derived from sustainable Portuguese cork oak, this inert material provides a unique combination of mould resistance, structural aeration, and habitat support for microscopic "clean-up crews." Why you will love it: Naturally Mould & Rot Resistant: Powered by suberin, a waxy biopolymer that naturally repels water and prevents the development of mould or rot, even in 90-100% humidity environments. The Ultimate Bioactive Media: The textured, irregular surface of cork pebbles creates a perfect micro-habitat for beneficial microfauna like isopods and springtails, supporting a self-cleaning ecosystem. Ultra Lightweight: Approximately 60% lighter than traditional clay pebbles (LECA) or river rocks, it is the ideal choice for glass terrariums and large planters while making handling easier and safer. Precision Aeration Matrix: The honeycomb cellular structure prevents soil compaction and ensures oxygen reaches plant roots, effectively stopping root rot before it starts. Fungus Gnat Fortress: When used as a topper, it creates a dry, chemical-free barrier that prevents adult fungus gnats from reaching moist soil to lay eggs. How to use: 1. For Houseplants (Soil Topper): Spread a 1–2 cm layer over the surface of the potting mix to regulate moisture and deter pests. Pro-Tip: Use a fine-spout watering can or "bottom watering" to prevent the lightweight pebbles from shifting. 2. For Terrariums (Drainage Layer / False Bottom): Replace heavy clay pebbles with a 5 cm base layer of cork pebbles. Cover with a mesh barrier before adding soil to create a "bio-active reservoir" that protects against waterlogging. 3. For Bioactive Setups (Substrate Amendment): Mix at a ratio of 30% cork to 70% soil/coco-coir. This prevents the substrate from settling and creates permanent air pockets for roots and microfauna. 4. For Orchids & Epiphytes: Use as a high-drainage "bark" alternative. The pH-neutral granules provide the stability of stone with the moisture-wicking properties of natural bark.
