Canna Nitric Acid pH Down

pH down solution for use in the early stages of plant growth - as opposed to the normal type of PH down sold for use in hydroponic systems that contain 81% phosphoric acid, this product contains 38% nitric acid.

This makes it especially suitable for use with grow nutrients in very hard water areas, it will have less effect on the overall NPK of the solution when added in relatively large amounts.

As with all pH adjusters make sure you handle it with care, it may be a slightly diluted form of acid but it's still a acid capable of causing serious injury if used incorrectly.
