NPK Industries RAW Calcium/Mag - 2 Oz

Calcium and Magnesium Support Without Salty Media - 2 Oz

Calcium and magnesium shortfalls slow growth, and heavy-handed fixes can leave salts building up in the root zone. This supplement uses a water soluble blend of calcium nitrate and magnesium sulfate, with the ratio of each element balanced so it does not leave the media salty. It contains 15% calcium and 3% magnesium.

The 2 Oz bottle is a low-commitment way to try the product. It suits home gardeners, small indoor setups, and commercial growers who want to test it before scaling up. Low dilution rates mean a little goes a long way.
