These pH adjustment solutions are specially prepared for use in hydroponics. They are extremely concentrated and care must be taken when using them. Organic acid is a pure organic alternative to lower the pH of solutions.

pH+ is a buffer/alkaline solution composed of potassium bicarbonate and potassium hydroxide to raise the pH of nutrient solutions, at any stage of the plant’s vegetative cycle.

There are two different versions, one of 5% for small corrections and a more concentrated one, 20%, for larger corrections.

Different versions of pH- are also available.
