Cal Mag Plus 2-0-0 Concentrate (Contains 0.1% Iron EDTA)

$ 29.99

Greenway Biotech's Cal Mag Plus contains a balanced ratio of Calcium, Magnesium, and Iron, which are critical throughout all stages of growth, especially in heavily blooming plants and annuals. Calcium and Magnesium are necessary for the prevention of blossom end rot in tomatoes and peppers, as well as the reduction of tip burn in lettuce. When used in combination with other nutrients Cal Mag Plus functions as a catalyst to increase the uptake of essential minerals.

At Greenway Biotech, Inc., we decided to sell pure concentrated Cal Mag Plus in powder form, increasing product yield while reducing excessive shipping cost. Doing so allows us to provide you with the highest quality Cal Mag Plus at a fraction of the cost. Another benefit to powder concentrate is that you can easily alter the concentration of the product to suit your particular needs.
