Professor Nutrients Extreme Boost (Powder PK Booster - 250g / 500g)

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.
