C-PK is the first PK booster combined with encapsulated Calcium Chloride.
The Calcium Chloride ensures that the Potassium is better transported and absorbed by the plant.
This way your plant creates harder, more compact and shiny fruits / flowers. In addition, the Phosphorus in combination with encapsulated Calcium Chloride provides a larger and more sterile root system.
Your plant can absorb C-PK in a larger PH range (between PH 4.0 and PH 8.0).
C-PK also has a cleaning effect on the irrigation system and dissolves remaining fertiliser salts. C-PK can be combined with all types of fertilisers.
Use C-PK in the last 3 weeks before harvest (every watering).
