Directions for Use:

The volume needed to achieve your desired pH will vary depending on your source water and the products you use in it to make up your solution. Apply very small amounts to the solution you wish to increase the pH of and mix well to allow pH reading to stabilize before adding more. Repeat until your target value is reached. For recirculating systems, check the pH daily.

There are many factors that affect ideal pH like: crop, stage of growth, and total ion exchange capacity. Recommended pH for most plants is: 5.5-6.5

Contains: Hydroxylated Water
