Botanicare Cal-Mag Plus 55 Gallon – 55 Gallons

Botanicare Cal-Mag Plus Calcium Magnesium Supplement — 55-Gallon Format Botanicare Cal-Mag Plus calcium magnesium supplement is a fortified blend of calcium, magnesium, and iron designed to prevent and correct common deficiencies that limit growth in high-demand cultivation programs. Particularly effective for growers using reverse osmosis water or coco coir-based media — both of which deplete available calcium and magnesium — this formula replenishes key minerals and restores optimal nutrient balance. The 55-gallon format supports extended feeding schedules for professional and semi-commercial operations. Cal-Mag Supplement for Hydroponics, Coco Coir, and Foliar Applications This Cal-Mag supplement for hydroponics and coco coir integrates into existing nutrient programs as a targeted mineral correction, applicable in hydroponic reservoirs, soil-based gardens, and as a foliar spray for rapid absorption. By correcting calcium and magnesium deficiencies at the source, plants develop stronger cell structure, enhanced nutrient uptake efficiency, and improved overall vitality across both vegetative and flowering stages. Key Features Calcium, Magnesium, and Iron Formula: Addresses the three most commonly deficient secondary and micro-minerals in high-production cultivation, particularly in RO-water and coco coir programs. RO Water and Coco Coir Compatibility: Specifically effective for operations using reverse osmosis water or coco coir media, which both strip available calcium and magnesium and require supplemental correction. Stronger Cell Structure: Calcium supports cell wall integrity and nutrient transport while magnesium activates chlorophyll and enzyme systems, together improving structural and metabolic plant health. Foliar and Root-Zone Application: Can be applied directly to the root zone via reservoir or drip systems, or as a foliar spray for rapid leaf-level absorption during acute deficiency correction. 55-Gallon Professional Supply: Extended-volume format suited for mid-scale and professional grows running continuous Cal-Mag programs without frequent restocking interruptions.
