Mad Farmer N.U.T.S. is a 100% organic, cold water extracted fulvic acid derived from humic shale. N.U.T.S. promotes an increase in nutrient uptake as well as a boost in vitality. Fulvic acid aids in nutrient uptake by acting as a natural chelating* agent when added to a liquid nutrient solution. The low molecular size and weight of the fulvic acid molecule allow it to penetrate plant membranes. Essential nutrients and trace elements in fertilizers attach to the fulvic acid and “piggyback” their way into the cell walls of the plant.
