Used for lowering the pH of a nutrient solution this 81% phosphoric acid is a cost effective solution for your pH adjustment 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 recommend diluting the phosphoric acid down with water before using to adjust the pH. Using neat can be tricky as it is so concentrated.
