About the Product

Getting a soluble form of calcium and magnesium for organic growing is tough. A lot of the products on sale for conventional growers are based on synthetic chemicals and chelates. Plus, most of the organic calcium products are insoluble powders (e.g. lime and gypsum). Organic Cal-Mag utilizes a a unique manufacturing process to combine organically approved ingredients into one fully soluble liquid product.

Why does Organic Cal-Mag have a pink hue?

Organic sources of calcium and magnesium always have a pink colour (see the Dolomite Mountains as a great example!). Organic Cal-Mag products that are white in colour invariably contain no magnesium. This can lead to chlorosis due to a lack of magnesium in the product. Furthermore, any calcium in the product then goes on to interfere with the uptake and use of magnesium from the base feed. For this reason, we ensure that Organic Cal-Mag has ample levels of magnesium in it, thus giving the pink hue.

Why such a low dose rate?

We use only the finest organic starting materials and provide a true analysis of the actual nutritional content. Give the bottle a shake and see how thick and viscous the product; it is packed full of calcium and magnesium. As a result, you do not need to apply much to get massive gains in yield and quality in your crop.
