PH Down

Easy Hydro Grow pH Down is a pH adjustment solution for lowering the pH of nutrient solutions and irrigation water to the optimal range for cannabis cultivation. Maintaining correct pH is fundamental to cannabis nutrition: most nutrients are only available to roots within specific pH windows — slightly too high or too low locks out individual minerals despite them being present in the solution.

The product is a concentrated acid solution (typically phosphoric or citric acid-based) that rapidly lowers solution pH when added in small quantities. A small amount goes a long way — add drop by drop while monitoring with a calibrated pH meter until the target is reached.

Use whenever the nutrient solution or water pH reads above the target range (5.8–6.5 for soil, 5.5–6.0 for hydro/coco). Always add pH Down after all nutrients are mixed, as nutrients affect final pH. Made by Easy Hydro Grow.
