Grotek Core


Grotek Core is based on plant matter, which not only provides key nutrients but also plant and mineral derived metabolites. At the heart of our line is the essential NPK that provides a foundation for our multi-product Grotek Green Line.


Grotek Core

Grotek Core is composed of sugar beet molasses, which provide essential minerals and key organic metabolites. With over 25% organic matter, this liquid directly impacts the soil. High concentrations of fermented organic matter, along with low levels of available carbohydrates, support soil biology. These beneficial microbes help convert nutrients to forms that plants can easily absorb. Containing all of the necessary macronutrients required for plant development, Core is effective in both true soil and water-based hydroponic systems, and can even be used in commercial injection systems.
