Emerald Harvest Cali Pro Grow A+B

Cali Pro Grow A&B is the vegetative-stage formulation in Emerald Harvest's two-part base nutrient system, designed for growers who want professional results without the complexity of a three-part program. The two-part format removes the ratio decisions that come with three-part systems while maintaining a complete, precisely balanced nutrient profile: simply mix equal volumes of A and B at the recommended application rate, and the plant receives everything it needs for productive vegetative growth.

The formulation is nitrogen-rich to support vigorous shoot and stem development through the growth phase, with chelated iron, copper, manganese, and zinc alongside cobalt and all other essential micronutrients supplied in forms the plant can access immediately. Secondary macronutrients calcium, magnesium, and sulphur are included at the concentrations required to support strong cell development and photosynthetic efficiency. Raw materials are sourced to the highest grade available. Shelf life of three years or more under normal storage conditions. Switch to Cali Pro Bloom A&B for the flowering stage.
