Cal-Mag Plant Food & Supplements

We offer a wide selection of Cal-Mag Supplements; essential for healthy plants and beneficial for most plants with signs of mineral deficiencies. Our high-quality selection of Cal-Mag plant food ensures your plants get additional calcium and magnesium in a highly soluble form. Cal-Mag additives are a must have in hydroponic gardens because certain grow media leach out nutrients – effectively making a balanced plant nutrient unbalanced. When growing in media like coco, additional calcium and magnesium is necessary for a balanced nutrition for healthy plants. High quality Cal-Mag plant food will prevent mineral deficiencies and avoid plant diseases that arise. At Discounted Hydroponics we proudly offer the finest Cal-Mag supplements including: Nature’s Nectar Calcium Magnesium and Vegamatrix Boost. Browse our wide selection and find the best deals available online. Contact us if you need help choosing the right product for your needs; we are happy to help!
