One of the most highly regarded products in the Canna range, Canna PK 13/14 is a potent mix of pure, concentrated phosphorous and potassium that intensifies flowering and enhances yields. Essential elements for the flowering phase, phosphorous and potassium perform different but related roles in ensuring your crop fulfils its full potential. 

Phosphorous has a hand in plant metabolism, energy transfer, and cell formation whilst potassium is essential for transporting water and nutrition, plant rigidity, and sugar production. All these processes are at their height during the flowering phase, the exact point at which Canna PK 13/14 should be introduced.

Compatible with any watering system, substrate, and with all mineral nutrient regimes, Canna PK 13/14 works particularly when combined with Canna Boost. It is administered via the roots, works with hard or soft water, and is ideal for short cycle plant varieties.
