PH Down (Phosphoric Acid)

Liquid to reduce acidity (PH) in water.

This bottle contains phosphoric acid at 22% concentration, which will quickly and efficiently reduce your nutrient solution to make the nutrients more available for plant absorption.

Advice for gardeners:

The acidity level in tap water is between 7.0 to 8.0 PH.

Hydroponic nutrients are usually acidic. Mixed with tap water will usually lower the acidity of the level to the appropriate range for plants (5.5-6.5). The acidity level in the water should be checked only after adding the fertilizers.
