PK Boost provides phosphorus (P) and potassium (K) in pure form. This additive is rich in minerals needed to promote strong flowering or fruiting and can make the difference between amateur and professional results in cultivation.
It is suitable as a supplement to the basic flowering fertilization.
Recommended dosage: 1 ml per liter, once a week. PK Boost 14:15 at a dosage of 1 ml per liter increases the EC value by approximately 0.35 mS/cm and adds:
- P - approx. 60 ppm
- K - approx. 125 ppm
