CANNA PK 13/14

  • CANNA PK 13/14 is a mixture of top-quality nutritional minerals that stimulate flowering.
  • This product has been developed for the flowering phase of fast-growing plants.
  • PK 13/14 is easy to use and high yields are easily achieved.
  • PK 13/14 is a high-grade mixture of phosphorus and potassium that is added during the flowering phase.
  • Both elements play a big role during the flowering phase of fast growing plants.

Your plants will reap the benefits of Canna 13/14's key ingredients for blooming over a longer time period, which leads to more beautiful blooms and higher quality.
