– ESSENTIAL ELEMENTS –

At the heart of our line is the essential NPK that provides a foundation for our multi-product Grotek Green Line. Core™ is based on plant matter, which not only provides key nutrients but also plant and mineral derived metabolites. This formula can be used to support beneficial soil biology in the rhizosphere, increasing production of substances known to benefit plant growth. Just like the rest of the Grotek Green Line, Core is suitable for all types of growing from gardens to water-based hydroponic systems.

Application Rate: 1L makes 333L of solution. Mix 3-4 ml per 1L of water. Use on a weekly basis in soilless media, or 3-4 times a season outdoors. Product is best applied as a root drench.
