Use Bluelab® pH Up and Down to adjust nutrient solutions to the optimum range of pH and improve nutrient availability to plants. Bluelab's pH Down is made of 35 percent w/w (certified) phosphoric acid, and pH Up is made of 35 percent w/w (certified) potassium hydroxide. The premium-quality acid concentrations are easy to use in any growing system. Use undiluted with Bluelab® pH Controllers and Bluelab® pH Controller Connect.
If your pH isn't in the right range—and that's 5.5-6.5 for most plant varieties—your nutrients are likely wasted. Too high or too low, and you're in trouble. The result is nutrient deficiency or complete nutrient lockout. A sure way to unhappy, unhealthy—even dying—plants.
Bluelab pH Down Solution is formulated to the highest standards. Just add what's required to reduce pH. Your plants will thank you for it. The main thing is, you'll see the difference in your harvest. Optimum inputs. Optimum results. Simple.
