Bluelab pH Down

SKU: BLU8005

Optimum growth needs optimum pH. And Bluelab makes optimum simple.

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.
