Frequently Asked Questions
Why is pH important for hydroponics?
pH is a measure of the acidity or alkalinity of your nutrient solution. Maintaining the correct pH level, typically between 5.5 and 6.5, is crucial because it directly affects a plant's ability to absorb essential nutrients. If the pH is too high or too low, nutrients can become "locked out," leading to deficiencies, stunted growth, and poor yields.How often should I test my pH level?
It's best to check and adjust your pH levels daily, especially when first setting up a new system or adding new nutrients. This helps you get a feel for how your system's pH fluctuates and allows you to make timely adjustments to keep it within the optimal range for your plants.SKU: 941 Free delivery on orders over £60*
