ur Macadamia Nut Shells are a high-performance, natural substrate component prized for their exceptional drainage, durability, and sustainability. Sourced from locally processed macadamia shells, this medium provides excellent airflow around roots while resisting breakdown over time.

Ideal for orchids, aroids, and exotic plants that demand sharp drainage and high oxygen availability, macadamia shells help prevent compaction and root rot while maintaining a stable structure in both pots and mixed substrates.

Naturally hard and slow to decompose, they are an excellent alternative or complement to bark and charcoal, especially in warm, humid growing conditions.
