Technical Grade Sulfuric Acid 40% — 5 Gallon Jerrycan

Professional-grade sulfuric acid for precise pH correction in irrigation, fertigation, and hydroponic systems. At 40% concentration, this technical grade formulation is the preferred choice for commercial growers managing high-alkalinity source water, delivering reliable, consistent pH reduction without introducing unwanted ions into your nutrient solution. The 5 gallon jerrycan is ideal for mid-to-large scale operations running continuous pH dosing programs.

⚠️ HAZARDOUS MATERIAL — UN2796, Class 8, Packing Group II. Sulfuric acid with 51% or less acid concentration. Handle with appropriate PPE. Review SDS before use.
