Silica Additive for Orchids & Exotic Plants

Silica is an optional, advanced supplement used by experienced growers to support stronger roots and firmer leaf structure. When used correctly and sparingly, it can improve plant resilience. Silica is not essential for orchid health and can be safely skipped if unsure.

This product is intended for growers who understand low-dose supplementation and proper spacing between feeds.

Benefits

• Supports stronger, more resilient root systems

• Helps improve leaf firmness and structural strength

• May assist plants under heat, airflow, or environmental stress

• Suitable for orchids and exotic plants when used correctly
