Bionova pH+ is a 24.5% potassium hydroxide solution. it is crucial to control the pH value of the water/nutrient solution with which we feed the plants. In fact, these absorb nutrients in the right quantities only when they are administered at the right pH value. If too high or too low the plants will not absorb all the nutrients they need.

Potassium hydroxide – Concentration 1:3000 – NPK 0-0-0

Increases the level of pH
Potassium hydroxide to 24.5%. This product is used to correct and increase the pH of the nutrient solution.

How To Use PH+:

  • It can be used from the first week of growth up to one or two before harvesting, it is important to perform a flush.
  • It can be mixed with all stimulators as well as mineral and universal products of the Bionova line.
  • It can be used with classic methods of watering.
  • By using potassium hydroxide to increase the pH of the water we are also adding available phosphorus (K) to the nutrient solution. So at the same time we are changing the reaction of the water and feeding the plants.
  • In case of a high demand for pH+ it is possible to reduce the dosage of the PK booster by 10% – 15%.
  • pH+ works very well in all cleaning operations such as irrigation system, growth tables, pots, nutrition tanks etc. without leaving residues.


Irrigation application
Constantly from 2-4 ml / 10 liters of water in relation to the pH of the same.
