About This

  • SOURCE OF CALCIUM MAGNESIUM & CHELATED IRON: Many varieties of flowering plants require higher levels of these micronutrients. Our well-balanced formula is designed to specifically address any plant deficiencies that may be present.
  • CORRECTS COMMON PLANT DEFICIENCIES: Sometimes an unhealthy plant may be suffering from a nutrient deficiency or even too much of one nutrient. Our CalMag & Iron supplement effectively corrects and remedies these micronutrient plant deficiencies.
  • NUTRIENT UPTAKE AND ABSORPTION: This formulae efficiently supports nutrient uptake and absorption by addressing any plant deficiencies in the first place, thus successfully supporting the vegetative and flowering stage of your plants.
  • SUITABLE FOR HYDROPONICS, SOIL, AND CONTAINER GARDENS: Nutrient systems and supplements are commonly used as hydroponic supplies and are a good solution for soil and container gardens, ensuring strong and healthy plants and yields.
  • OPTIMAL FOR COCO COIR MEDIUM AND REVERSE OSMOSIS WATER: Our supplemental CalMag & Iron by Humboldts Secret is highly recommended for plants growing in coco substrate or reverse osmosis water, as the absorption process becomes magnified.

    Loved the wildflower seed mix—sprouted fast, and the pollinators showed up within a week. Great way to help the bees!

    The cedar raised beds I ordered from GARDUCT smell amazing and feel rock‑solid. Absolutely worth every penny compared to the flimsy ones at big‑box stores.
