The VitaLink ESSENTIALS range are nutrient control products. Plants usually thrive in a pH range of 5.5-6.5 and the ESSENTIALS range has the products to allow you to achieve this. Our pH Up and Down adjustment solutions are specially prepared for use in hydroponics. They are extremely concentrated and care should be taken when in use. Our pH Down is 81% phosphoric acid and pH Up is 24% potassium hydroxide. For growers in very hard water areas we also offer Nitric Acid pH Down as an alternative to phosphoric acid because it affects the composition of the nutrients less. Keep away from children.
pH Down – high concentrated (81% phosphoric acid). Brings pH down, only little is needed.
pH Up – high concentrated (50% potassium hydroxide). Helps to adjust the pH up.
Why do we need the right pH?
The pH greatly affects the availability of the nutrients within solution. We set a pH target of 5.8 because it is at this point that most elements are available to the plant.
