additional information

Calcium is key to a plant’s success, and Grotek™ Vital™ gives growers a chance to get the level of calcium just right for their plants. As an isolated component, it is possible to dial in a precise level of calcium. The formula also has ultra-low chloride content to ensure better health for the plant and the soil. Vital™ is an excellent choice for all gardens, but is a necessity when growing in Coco.
