PK 13/14


Brilliant blossoms

During the flowering period the need for phosphorus and potassium increases more and more. Flowering results in propagation, a large amount of genetic material (DNA) is built up and is accompanied by an increasing demand for energy. Both the energy molecules and the DNA strands contain a large amount of phosphate. Potassium is crucial for the transport of water and particles into the roots up to the leaves. It also regulates the uptake of carbon dioxide and influences the photosynthetic capacity.

PK 13/14 is a practical tool to gradually increase the PK content and avoid excessive amounts of PK in the early flowering phase, very important especially in hydroponic crops. 
  • Use together with the bloom fertiliser. 
  • Improves the flowering performance 
  • The right dose at the right time
2,5-15 ml / 10 L
  • Gradually increase the dosage starting in the second half of the flowering phase. 
  • For crops use only water one week before harvesting
PK fertiliser 9-7
Hesi PK 13/14 is available in the following quantities: 
  • 500 ml 
  • 1000 ml 
  • 5 L 
  • 10 L
  • 20 L

Did you know?

Potassium promotes photosynthesis by regulating the CO2 supply. However, an excess of potassium can lead to calcium and magnesium deficiency. Since magnesium is the central atom of leaf green (chlorophyll), photosynthesis would become faulty, although potassium in particular promotes photosynthesis by regulating the CO2 supply. The right mixture makes the difference.

All our fertilisers provide nutrients for plants to grow and thrive. They enrich your plant with the nutrients it needs, for a specific period of its life cycle. Fertilisers make your crops grow faster and larger, so yields will be increased. We divide the type of nutrients into different levels. The primary nutrients are nitrogen (N), phosphorus (P) and potassium (K). These three nutrients improve the growth and productiveness of the plant. Secondary nutrients are for example calcium (Ca), magnesium (Mg) and sulphur (S). There are further micro nutrients that complete the composition of each individual fertiliser. The Hesi fertilisers contain several different nutrients, blended to the perfect mix for your plants! Use our boosters alongside your fertiliser feed, to improve the metabolism and resistance of your plant.
