Professor's Nutrients Flower Boost | 1L, 2.5L, 5L, 10L, 20L | Concentrated PK Enhancer for Bigger Yields

🌸 Professor's Nutrients Flower Boost is a high grade, concentrated PK flower enhancer scientifically formulated to trigger early blooming, accelerate bud development, and help you pull larger, heavier, higher quality harvests every cycle.

Available in 1L, 2.5L, 5L, 10L and 20L to suit every size grow.

Why PK Is Everything in Flower

When your plants transition into the flowering stage, their nutritional needs shift dramatically. Phosphorus and Potassium become the two most critical elements for driving flower development, and simply continuing with your base nutrient alone is not enough to unlock your plant's full potential.

🌺 Phosphorus fuels new root formation, triggers blooming, and drives fruit and flower development right from the start of the flowering window. Potassium, often called the quality element, is rapidly absorbed through the roots and directly influences the shape, colour, size, and taste of your final harvest.

The Right Balance Matters

One of the most common mistakes growers make is pushing Potassium too hard in early flower. High doses of Potassium can block Calcium uptake and trigger deficiencies that set your grow back significantly. Flower Boost is carefully formulated with the precise ratio of P and K your plants need at each stage of the flowering cycle, so you get maximum results without the risk.

⚖️ No guesswork. No lockout. Just the right PK at the right time.
