Absorption of various mineral elements varies according to the acidity of the growing medium. Optimum availability lies within a pH range generally recommended between 5.5 and 6.5. We recommend staying in the lower range: between 5.5 and 6.2.
pH+
High-quality pH regulator and source of silica for hydroponics, coir and soil
To control pH by optimizing silica levels
While the need for a pH increase seems like an aberration for hard water growers, too low a pH is often a problem in areas with very soft water, or for users of osmosis water. Terra Aquatica pH+ provides this regulation, and is also a valuable source of silica - often lacking in hydroponics - due to its very low solubility. High silica levels make a real contribution to plant health. That's why we add as much as possible to our products.
