Fulvic Acid is far superior in action to humic acid due to it's low molecular weight, which enables it to go through the cell membranes of roots and leaves. Where humic acid is soluble in alkaline media only, Fulvic Acid is soluble in all media. Fulvic acid will power up the entire plant , from the roots to the growing tips, by accentuating the production of nucleic acids and photosynthesis. Used as a foliar or add to solutions.
