PKB 16/21 – Professional PK Flowering Additive

Proactive PKB 16/21 is a high-performance professional flowering additive featuring a completely unique phosphorus-to-potassium ratio of 16/21, enhanced with added boron to maximize flowering performance and crop quality.

Designed specifically for the bloom phase, PKB 16/21 enhances photosynthesis, supports efficient water regulation, and delivers targeted nutritional support precisely when plants demand elevated PK levels the most. This results in improved flower development, increased yield potential, and enhanced overall plant performance.

The formulation is complemented with boron in a selected, high-purity form to ensure optimal efficiency and uptake. Boron plays a critical role in improving the transport of sugars throughout the plant, directly supporting flower formation and yield. It is also essential for healthy cell division and strong cell wall development, contributing to stronger, healthier plants and improved crop quality.
