- ESSENTIAL ELEMENTS -
Core™ from the Grotek Green Line stands as the cornerstone of the range, delivering the crucial NPK (Nitrogen, Phosphorus, and Potassium) nutrients that lay the groundwork for healthy plant development. Formulated with a base of plant matter, Core™ not only supplies these essential nutrients but also enriches your plants with both plant and mineral-derived metabolites. These valuable compounds are pivotal in fostering a vibrant soil ecosystem, particularly in the rhizosphere where they stimulate the production of substances beneficial to plant growth.
Just like the rest of the Grotek Green Line, Core™ is versatile and suitable for a wide array of growing environments, from traditional gardens to the latest in water-based hydroponic systems. By integrating Core™ into your feeding regimen, you're not just nourishing your houseplants; you're actively supporting the beneficial soil biology that underpins robust plant growth and vitality, ensuring your indoor garden flourishes.
