Product information
CANNA PK 13/14 is a high-quality additive of phosphorus and potassium. These minerals stimulate the flowering of fast-growing plants. If you apply PK 13/14 at the right time, you will get amazing results. It is suitable for any medium.

Advantages of CANNA PK13/14

Pure elements to stimulate flowering

CANNA PK 13/14 is a high-quality mixture of phosphorus and potassium that is added during the flowering phase. Both elements play a major role during the generative phase of plants. Thanks to a special production process, CANNA has succeeded in combining pure phosphorus and potassium in very high concentrations. This makes PK 13/14 quickly and immediately available to the plant.

Phosphorus (P) is a macro-nutrient element for every plant. It plays a key role in metabolism and energy transfer. In the flowering phase, extra phosphorus is needed. Phosphorus enhances cell formation in flowers, among other things.

Potassium (K) is also a macro-nutrient element. It is found throughout the plant and is necessary for many of its activities. It is essential for the transport of water and nutrients and it is responsible for the quality and rigidity of the plant. In addition, it manages countless other processes such as sugar production. Potassium ensures that the plant can produce sufficient sugars during flowering, which are essential for the development of the flowers.

Perfect combination with CANNABOOST

There comes a time during plant development when the need for phosphorus and potassium increases dramatically. If CANNA PK 13/14 is given at this time, the increased needs of the flowering plant will be satisfied and the fruits will reach maximum development. CANNABOOST improves metabolism and has a strengthening effect on PK 13/14. This perfect combination ensures that the plant blooms more exuberantly.

Suitable for any medium
PK 13/14 can be used in any medium and is suitable for cultivation on soil, in recirculation systems, when growing on coco, in run-to-waste systems, and can be used in both indoor and outdoor cultivation.


  • Shake the bottle well before use.

  • Add CANNA PK 13/14 to the nutrient tank three to four weeks before harvesting.

  • Use CANNA PK 13/14 for a maximum of one week and during flower formation over the entire plant.

  • CANNA PK 13/14 can be administered without any problems at a concentration of 15 ml per 10 liters of tap water, provided the EC value of your standard food does not exceed 1.8 mS/cm. EC and pH values ​​should always be checked after CANNA PK 13/14 has been added.

  • CANNA PK 13/14 can, under normal conditions, be used in combination with all CANNA products.

  • Combined with CANNA pH MIN bloom, saturation can occur in the nutrient vessel in exceptional cases. Should this happen, we recommend using CANNA pH MIN growth (nitric acid instead of phosphoric acid).

  • Avoid high pH values ​​(above 7.0) in the nutrient vessel after CANNA PK 13/14 has been administered. A high pH level increases the risk of saturation. Saturation results in irreversible salt compounds, which the plant can no longer absorb naturally. The feed in the vessel has become unusable and the vessel must be cleaned thoroughly to prevent further precipitation.

  •  When using a feed computer, it is possible to add CANNA PK 13/14 in diluted form to the B feed (and if no additional pump can be added). Never use CANNA PK 13/14 in its pure form, because then B-nutrients can become unstable and possibly precipitate.

Other instructions

  • Over-fertilizing has a negative effect on nature, the soil and the plant.

  •  Store frost-free, closed and dark.

  • Keep out of reach of children.
