FLOWER BOOST – PK Enhancer
Phosphorus & Potassium (PK): The fundamental raw ingredients your plants need to develop fruit and flowers.
The best way to maximise yields is by incorporating the correct flowering stimulant into your feeding program. It can mean the difference between a highly successful harvest or one that leaves you disappointed. It is at this stage of the cycle that simply feeding nutrients alone is not enough.
In the early flowering stage, Phosphorus is used by plants to help form new roots, promote blooming, increase fruit and flowers and maximise crop quality and harvest size.
Potassium is often referred to as the ‘quality element’, easily absorbed through the roots, it is known to contribute to shape, colour, size and taste.
Some people make the mistake of feeding high levels of Potassium in the early stages of flower, thinking that more is better. However, these high doses can block out calcium and cause a calcium deficiency in your plants. Therefore, it is important to use the right balance of PK throughout the flowering stage.
The Professor’s Flower Boost is a high grade, concentrated PK flower enhancer. Scientifically formulated to initiate early flowering and node development, Flower Boost provides plants with the perfect ratio of PK to produce a large, high quality yield. Whether you are cultivating flowering or fruiting plants, Flower Boost will give your plants the exact PK ratio they need to release their full potential.
So, what exactly does Flower Boost do?
- Boosts Early Blooms and Bigger Yields
- Activates Flowering Enzyme production
- Provides perfect ratios of P and K to boost flower development
- Faster flower growth and bud onset
- Larger Heavier Blooms of a higher quality
- Aids in energy transfer and storage of carbohydrates

Application
To achieve maximum yield, Flower Boost should be replaced with Extreme Boost in the final 3 weeks.
Hydroponics: Use 2ml Flower Boost per 1L of nutrient solution.
Soil: Use 1.5ml Flower Boost per 1L of nutrient solution.
