Adjusting the level of pH can be quite a hassle if you don’t have the right tools to do the job. After testing your levels with pH meter, you might find your pH levels not where you want them to be. pH adjusters help you get rid of this problem.

What are pH adjusters?

Like its name suggests, pH adjusters are used to keep the plant's pH levels within the ideal range. The adjusters can be used in both acidic and basic solutions. All you have to do is add a little pH up or down to the solution or you reservoir and you’re good to go.
