pH regulators are used to lower or raise the pH of water and nutrient solution. The right pH determines whether a plant can absorb the nutrients contained in the fertilizer. They are useful wherever plants are watered with nutrient solution - in pots, soilless cultivation and greenhouses.
In this collection, you will find pH minus and pH plus products. These are concentrated acids and bases - use them according to the label, add them in small portions, and wear protective gloves and goggles. You can find the full range in the all fertilizers category.
