Suitable for agricultural, commercial, and greenhouse irrigation systems. Available in convenient 1-gallon, economical 5-gallon, and bulk 55-gallon drums.

Application Guidance:

• Use only between growing cycles; avoid applying when plants are actively growing.
• Inject into irrigation lines, targeting a final pH range of 2.0-3.0 at outlets (drip emitters or hose bibs).
• In batching systems, pre-mix solution to achieve the same target pH.
• Operate the irrigation system until targeted pH is reached, then run an additional 10-15 minutes.
• Immediately clean or replace system filters after application.
• Thoroughly flush system afterward until clear, neutral pH water runs through all components (approximately 1-3 minutes per zone).

For optimal results, follow up treatment with an oxidizer product.
