Plug and Play Water Acidification Package

Most of the water in the South and South East contains appreciable amounts of calcium, giving it its characteristic “hardness”. These calcium levels can result in several problems, all of which can be alleviated by acidifying the water. Although pH 7 is “neutral” (not acidic or alkaline), it is not the optimum crop pH for irrigation on outdoor and container crops.

The recommended range of irrigation water pH and substrate solution pH for production depends on the crop. In general, pH should be 5.2-6.8 for irrigation water and 5.4-6.3 for substrate solution. If the pH and alkalinity is high, water may need acid treatment prior to use on crops.
