Powder A is the combination of plant available nitrogen and calcium that form the foundation of a complete nutrient regimen, providing plants with the essential nitrogen and calcium they need for strong, healthy vegetative growth. Nitrogen is a primary driver of chlorophyll production, ensuring lush, vibrant foliage and robust structural development. Calcium, on the other hand, plays a critical role in cell wall integrity, enzyme activity, and nutrient uptake, making it indispensable for resilient plant growth.

By keeping nitrogen and calcium in a standalone formula, Powder A allows growers to tailor their feeding regimen with precision. As flowering progresses and nitrogen demands decrease, growers can easily taper off Powder A while maintaining the micronutrient profile with Powder D. This flexibility ensures optimal growth without excessive nitrogen late in flower, reducing the risk of unwanted leafy growth and improving final yield quality. Lowering nitrogen levels in late flower has also been shown to enhance terpene production, leading to a more aromatic and flavorful final product.
