Bluelab pH Up, 1 Liter Bottle, case of 12

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 Up Solution is formulated to the highest standards. Just add what's required to raise 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.
