The chunkiest blend in the Bio Leaf range.

If you love the original Bio Leaf Aroid & Hoya Mix, this is the extra-chunky upgrade your plants will go wild for. Designed especially for slower-growing, salt-sensitive variegated plants, this coarse 8-20 mm blend delivers exceptional drainage, airflow, and root protection.

Why It's Special

• Ultra Free-Draining: Larger particles create maximum aeration, prevent compaction, and dramatically reduce the risk of rot.
• Perfect for Variegated Plants: Ideal for Monstera Thai Constellation, Monstera Albo, and other epiphytic aroids needing a drier, oxygen-rich substrate.
• Low Moisture Retention: Holds just enough water for slow, gentle release - perfect for plants with reduced photosynthesis.
• Bioactive Boost: Contains Bio Leaf's Bioactive Blend to support beneficial microbes, nutrient availability, and natural soil detoxification.
• Salt-Safe: Fertiliser-free and fast-draining to help prevent salt buildup and root burn.

Best For

• Well-established variegated aroids
• Epiphytic plants needing high airflow
• Mixing into standard aroid blends to boost drainage

(Note: For delicate or freshly rooted variegated plants, start with the Fine or Medium aroid blends.)
