Professor’s Nutrients Extreme Boost 500g

Size and Weight guaranteed!

Heavy fruiting and flowering plants require higher levels of Phosphorus and Potassium (PK) for larger blooms. Flower stimulants, like Professor’s Flower Boost, are 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.

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 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.

Extreme weight increases of more than 20% are commonly reported!


  • Creates harder flowers with more bud weight
