House & Garden

Shop House & Garden soluble dry base nutrients for a staged feeding program built around CalMag, Grow and Bloom. The 25 lb powders let growers measure each component by weight and adjust feeding to crop stage, source water and target nutrient-solution EC.

Choose Your Base Nutrients

• CalMag 12-0-0: Supplies nitrogen, calcium and magnesium. The House & Garden dry-base feed chart includes CalMag through vegetative and flowering stages.
• Grow 2-12-28: The vegetative-stage component in the dry three-part program, used alongside CalMag.
• Bloom 1-18-32: The flowering-stage component in the dry three-part program, used alongside CalMag.

Plan Feeding with the Manufacturer's Chart

The downloadable chart provides rates in grams per U.S. gallon of RO water for cuttings and seedlings, vegetative growth and an eight-week flowering schedule. Target EC values apply to the combined feeding program, not to CalMag alone. Follow product labels and adjust your program to crop needs and water quality.
