additional information

At the heart of our line is the essential NPK that provides the foundation for our multi-product formula. Core™ is based on plant matter, which provide key minerals but also high levels of humates and other plant and mineral derived metabolites. This formula can also be used to feed and stimulate soil biology, increasing production of substances known to accelerate plant growth. Just like the rest of the Grotek liquid organic range, Core™ is suitable for all types of growing, from outdoor gardens to water based hydroponic systems.
