RAW Calcium/ Mag, being in powder form is inherently light weight. If you need to transport plant feed some distance by hand, up some stairs to a flat for example, this could be the perfect product for you!
RAW Calcium/ Mag from NPK Industries is powder additive for the prevention and treatment of deficiencies. It contains 15% calcium in the form of calcium nitrate and 3% magnesium as magnesium sulphate. This is an ideal ratio of each element for maximum effect in the treatment of plants and it won’t leave the media with salty deposits.
This is a high concentration product and a little goes a long way! As with any calcium magnesium products, it is great for using alongside any other base nutrient regime. Many growers experience a need for these elements when using coco coir to grow plants as there is usually a deficit in these elements.
One of the best things about RAW powders is the number of single component products that make up the range. Using these, you can create “recipes” that really tailor to what your plants need at specific times. You can find some of these recipes on our website by following this link. Should you think your plants are missing just a little of one particular element, RAW powders are great for that too! You can find more information on this, and all the other RAW nutrients and additives on the NPK Website. (Opens a new window in your browser).
