This pack includes 1 Bag of Nutrient B. The nutrients are a blend of raw earth minerals - a balanced recipe of everything the plants need for healthy growth. Includes: calcium and nitrogen. *Please note this product does not include a scoop. Part B has a tendency to absorb water from its environment. In some instances, this can cause it to clump or liquefy. This will not impact the effectiveness of the nutrient. Continue to use the same recommended scoops.
