Hy-gen pH Down Phosphoric Acid 80% 250mL / 1L / 5L – 0-25l-250ml

PLEASE NOTE: PICK UP IN-STORE ONLY – This product is classed as a dangerous good. In hydroponics “pH” is an extremely important factor. When it is poorly monitored or controlled, plants can become sick or die. It is therefore recommended that pH is tested daily. Hy-Gen pH Up and Hy-Gen pH Down provide the grower with an added control in maintaining optimum pH levels and hence maximizing nutrient availability and plant productivity. A too high or too low pH can complicate the absorption of important nutrients such as iron, calcium, magnesium, etc. Generally the pH of the hydroponic solution should be 6.3. It is acceptable, however, to maintain the pH in the range of 6.0 to 6.5. For rockwool a lower pH of 5.8 to 6.0 is recommended. This allows for optimum nutrient solubility and availability.
