Calcium is a very important nutrient for flowers. Without enough calcium, plant leaves mutate and wither, buds die, stalks go brittle, growth is stunted, roots fail, and plants become susceptible to stem and root pathogens. Our competitors� fertilizers don�t have enough of the right kinds of calcium in their products, and your plants can�t drink milk to get calcium. That�s why we created SensiCal Grow. This powerful new product supplies three different sources of Calcium, including Calcium Chelate, along with Magnesium, Iron, Manganese, Zinc, Copper, Boron, Molybdenum and Cobalt. SensiCal Grow supplies these essentials in the exact ratios needed by plants.
