Calcined Clay undergoes a high-temperature process, resulting in a reduction in size. This treatment produces a lightweight and porous substance that improves drainage, aeration, water regulation, and oxygenation for plants. Its natural pH balance and nutrient-holding capabilities make it a durable material that remains intact over time. This makes it ideal for plant species such as bonsai, cactus, succulent, and orchid as a soil amendment.

USES: This substrate may not be suitable for all succulent species, specifically those that were first grown in soil and then transitioned to calcined clay. However, it is ideal for rooting plants, particularly haworthia species. Additionally, the non-floating nature of calcined clay allows for easy submergence or soaking of plants in water to eradicate pests.
