## Description

At Humboldt Nutrients we don't make new products very often, but when we do we take it to another level. Well, we decided to make the best Calcium Magnesium product in the marketplace and we accomplished just that. With an available 2%(N), 3.4%(Ca) and 1.4%(Mg) + micronutrients, Calyx Magnum gives gardeners vital nutrients needed for plant development and growth. Another huge benefit is that we created Calyx Magnum without the use of chemical chelates like EDTA, which is so prevalent in other Cal Mag products on the market. Instead of chemical chelates like EDTA, Calyx Magnum utilizes plant based amino acids as a chelating agent. This means that Calyx Magnum is biodegradable, making it a better choice for the conscious and sustainable minded gardener.
