Product Review
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 & we accomplished just that. With an available 2%(n), 3.4%(Ca) & 1.4%(Mg) + micronutrients, calyx Magnum gives gardeners vital nutrients needed for plant development & growth. Another huge benefit is that we created calyx Magnum without the use of chemical chelates like delta, which is so prevalent in other Cal Mag products on the market. Instead of chemical chelates like delta, 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 & sustainable minded gardener.
