Plagron pH- (59%) 1 L

Ultra-strong pH Down for precise control in Veg & Bloom**

Plagron pH- (59%) is a
highly concentrated pH reducer based on nitric acid,
developed for growers who need maximum control
over their nutrient solution – whether in soil, coco, or hydro.

extremely small amounts to precisely adjust pH levels.
Perfect for anyone who wants stable nutrient uptake,
fewer fluctuations, and absolute precision.

pH- (59%) = strong acid, strong control.
