Description
Green House Feeding Calmag is a water-soluble fertilizer containing nitrogen (13.5%), calcium (16.7%), and magnesium (6.0%). Its high solubility makes nutrients readily available to plants. It's ideal for foliar application, hydroponics, and fertigation (applying liquid or water-soluble fertilizers via an irrigation system) and promotes healthy growth, vigorous blooms, and improved fruit quality. Free of chlorine, sodium, and heavy metals, GHF Calmag is a clean and efficient nutrient solution for correcting deficiencies or supporting ongoing plant nutrition.
