As plants approach the final phase, a more concentrated and balanced PK is needed to achieve larger, harder and more dense flowers, creating heavier yields. 

The Professor's Extreme Boost does just this, and takes it to the next level by providing very high amounts of pure PK exactly when the plants demands it. It used high grade minerals in extreme concentrations, aidig and sccelertaing the final ripening and bulking process in fuits and flowers, to ensure you get the msot of your yield.
