Bluelab pH DOWN 1 Liter


If your pH isn't in the right range (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.

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.
