Hard Water Grow Special

Your go-to for lush plants, even with the downsides of hard water










Peters® Excel Hard Water Grow Special is especially formulated to combat all those hard water issues: it has an acidifying effect on the water, with an HCO3-buffering effect that keeps your soil’s pH stable. It also improves the water’s quality, lowers its EC value, and neutralizes bicarbonate. Your plants will be at their best, thanks to plenty of chelated trace elements. Plus, it can prolong the life of your irrigation system by keeping it cleaner and preventing drippers from blocking. Its M-77 chelating complex ensures maximum availability and absorbability.

  • Ensures your plants thrive in hard-water conditions

  • Protects drippers and irrigation systems from limescale blockages

  • Improved water quality and stable pH for your soil
