Type and Usage

PK 13 14 by HESI is a potent flowering stimulant and bud fattener of mineral origin. Suitable for all types of substrates and automatic irrigation systems.

Plant Benefits

  • Phosphorus increases the size of the buds, it's essential for photosynthesis and is involved in the formation of cannabinoids and terpenes.
  • Potassium participates in the metabolic process that originates cannabinoids, increasing vigor in flowering and plant resistance.
  • With HESI's PK 13 14, you'll boost the yield of the buds, which will be denser, more resinous, with a better aroma and taste.

Usage and Doses

  • Apply from the second half of flowering until a week before harvesting where we'll only water with pure water.
  • Start with a dose of 0.25ml per 1 liter of water and gradually increase the dose each week until reaching a maximum of 1.5ml per liter of water.
  • Water only with water in the final week.

La Huerta's Opinion

PK 13 14 by HESI is a flowering stimulant, to achieve optimal results it should be used along with a complete flowering fertilizer.

It's essential to use it alongside the regular flowering fertilizer, that is, HESI Hydro Flowering for hydroponic crops or Hesi Coco for coconut substrate crops.
