Cal-Mag by Emerald Harvest is a great quality additive with powerful ingredients like calcium and magnesium. Both nutrients are vitally important for the correct development of any strain. It is quite often hard for plants to get their needs fully covered. This product is the perfect ally to prevent such deficiencies.
Cal-Mag is very useful to obtain that extra bit of calcium and magnesium. It can be particularly handy if you use low mineral or osmotic water as it adds such nutrients and prevents future problems. Available in various formats to suit the needs of any grow, either hydroponic, aeroponic, soil or coco coir.
Cal-Mag’s main ingredient is calcium, which promotes greater root growth. This way, the plant can absorb as many nutrients from the soil as possible, which improves the protection against infections. On the other hand, magnesium activates some of the enzymes that boost nutrient absorption. Thanks to this combination, plants become greener and gain resistance against plagues, thus the yield will be larger.
What makes this product different from others is that it contains kelp. This marine vegetable is added to fertilizers due to its great properties as a bio-catalyst. It also serves as vegetable protein by improving plant growth with great quality nutrients.
