Professor�s Extreme Boost is ideal to use in the early bloom stage to encourage flower growth and bud onset. 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. Professor�s Extreme Boost takes it to the next level by providing very high amounts of pure PK exactly when the plant demands it. It uses high grade minerals in extreme concentrations, aiding and accelerating the final ripening and bulking process in fruits and flowers, to ensure you get the most out of your yield.
