FLOWER BOOST – PK Enhancer

EARLY BLOOM ACTIVATOR FOR BIGGER, BETTER YIELDS

Give your plants the perfect start to their flowering phase with Professor’s Flower Boost—a powerful liquid PK enhancer designed to initiate early flower development and maximise final yields.

This premium-grade liquid formula delivers the ideal balance of Phosphorus (P) and Potassium (K) to trigger flower formation, increase bud sites, and support early bloom progression. While base nutrients keep plants fed, Flower Boost provides the extra push needed to unlock their full flowering potential.

Phosphorus encourages root growth and early flower formation, while Potassium improves shape, size, and flavour. Unlike some high-PK products that can cause calcium lockout when used too early, Flower Boost is carefully formulated to provide just the right ratio—safely and effectively.

Perfect for fruiting and flowering plants in hydroponic and coco systems, this fast-acting liquid is easy to mix and works quickly to drive results.
