Provides a Range of Minerals

Cal-Max™is a rapid source of nitrogen and magnesium to support chlorophyll and protein development, which quickly re-greens plants low in nitrogen. Chelated iron adds more deficiency fighting power for lush green growth. Added calcium supports plant strength and assists in times of peak growth.

Helps with High Temperatures & Humidity

During periods of peak growth or high temperature, calcium can be a limiting factor. This formula is designed to drive calcium movement to help avert associated plant damage. Even with sufficient calcium in the soil, high temperature and humidity may hinder plants from absorbing enough. Consider using a foliar application at that point to address the issue.

Alleviates Nutrient Deficiencies in Coir-Based Medium

Cal-Max™ is amazing for amending coco coir based media, with fast acting nitrogen and a strong calcium source to assist in buffering coir’s inherent imbalance.
