K Mag . . . what is it, and why do I need it?


If you’ve never heard of K Mag, you’re not alone. However, it’s a very valuable nutrient in your garden’s life cycle! Check out this review from one of our customers:

“Ah K-Mag – where have you been all this time? Never heard of this kind of mix before, and I find it very useful as a preventative measure against deficiencies that *might* occur. I’ve only used it at the strength mentioned in the mixing instructions. I’ve applied it on both mature and (very) young plants. The clones are sprayed at 2 weeks and the flowering plants are sprayed within the first two weeks of induction, while their metabolism is changing. These applications help prevent mag / sulfur deficiency, and I swear the clones look better even 24 hours after application. My only gripe – I wish calcium was thrown in this product, but I use their limestone powder as a top dressing instead.” – Mr. Jansen




But what is it for? Well, K Mag consists of: Magnesium (Mg), Potassium (POTASH) (K), and Sulfur(S). So we’ll break down what each does for your plants.

Magnesium: Magnesium is what helps your plants make chlorophyll.  Chlorophyll helps plants turn sunlight into energy via a chemical reaction within the plant itself.

Potassium (POTASH): Potassium is essential in the uptake of nitrogen, as well as the synthesis of protein and starch. Potassium is also necessary to aid in fruit formation, and increasing yield.

Sulfur (S): Sulfur  helps plants to build protein, and, according to the Sulfur Institute, sulfur contributes to increased plant yield by providing nutrients to the plant, the soil, as well as improving the use and efficiency of other nutrients, including (particularly) nitrogen and phosphorus. Oh – not to mention it makes garlic and asparagus taste better. Yup. 🙂

So, essentially, K Mag is great because it’s going to make your plants stronger throughout their root system, as well as help increase yield and assist your plant in utilizing more efficiently the nutrients which are already there.

  1. After 1 application at full strength (1oz/gal), immediate results! Plants became more vibrant within hours. Great as a soil soak for transplants, seedlings and soil mixes.
