Grow Green with ENVY™

Envy's CalMag+ leverages premium quality nutrients to consistently optimize yields and quality while stimulating rich, vibrant coloration to bring joy to both indoor and outdoor cultivators alike. This blend is suitable for all growth mediums, including hydroponic, soil and coco-coir.

The effect of Envy's Liquid CalMag+ blend across your entire garden can be profound, as it provides supplemental macronutrients in the form of calcium, magnesium, and iron - critically important elements for the efficient and continued growth and health of your plants. Calcium is responsible for the transportation of essential nutrients throughout your plants; strengthening cell walls and enabling other macronutrients to be transported from your growth media to where they are needed. This supplement alleviates the symptoms of calcium deficiency such as stunted growth, yellowing leaves, and blossom end rot in tomatoes. Magnesium is required for the production of chlorophyll, the foundation for photosynthesis, while it also strengthens cell walls, bolsters enzyme production and increases the viability of seeds during the germination process.
