A natural organic bio-stimulator

Despite the low level of nutrients found in natural soil-based environments, plant growth nevertheless occurs because the smallest humic acids channel available nutrients directly into nearby vegetation. By accelerating nutrient absorption at the root boundary zone where minerals enter the plant, small particle sized humic and fulvic acids optimize nutrient uptake in fast growing vegetation.
Fulvic is a mix of these acids with mostly fulvic but quite a bit of humic too, which gives it this slightly brownish colour.
