The CX Horticulture Nutrient Calculator is designed to provide you with a guide for mixing CX Horticulture UK nutrients and additives. You must always use suitable liquid measuring devices such as pipettes and measuring jugs, as well as accurate pH and EC measuring equipment. Never rely on nutrient calculators or Feed Charts alone, as water conditions can vary and affect the outcome of your nutrient solution.

Our nutrient calculator works better when calculating larger volumes of water, and we recommend anyone who’s mixing 20 litres of solution or less should use the mixing guidelines on our Basic Product Application Chart (see Downloads Page).
