Calyx Magnum

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.

Search Tips:
  • You may want to broaden your search. This can be accomplished by shortening or generalizing the words you using in your search.
  • If you are entering a part number, do not include any hyphens or other punctuation marks. You may even try using a portion of the number if it is a long one.
  • Spelling does makes a difference. Be sure to check for spelling errors as this will affect your results.
  • Mutations of a word also make a difference. For example, the word 'accessory' will return different results than 'accessories'.
  • Plural makes a difference too. Adding an 's' may impact results. Often it is better to search for the singular.
  • The search is not case sensitive, so you can type in all lower case, all caps, or any mixture.
  • Contact customer service for assistance if you still cannot find what you are looking for.
