Used for lowering the pH of a nutrient solution this 81% phosphoric acid is a cost effective solution for your pH adjustent needs.
Available in 250ml, 1l and 5l.
* Use sparingly this stuff is strong, if you are only mixing up small quantities of nutrient at a time we reccomend first diluting the phosphoric acid down with water before using to adjust the pH as using neat can be tricky with it being so strong.
