Lime as a pH up? Lime is best used as a SOIL amendment, and use a proper pH up to fix a troublesome combination of your source water plus ferts. If you want to add calcium, use calmag. Soil pH range is 6.4-6.8 btw. Since most soils will tend to drift lower rather than higher, set your pH to 6.8 to water, unless you observe something else in your own setup.
stinkyattic Reviewed by stinkyattic on . Help with checking pH So I've never checked pH before and I'm a little confused on how this is to be done. I have one of the liquid testing kits with the little capsules and the container with the color chart. So container has two lines. The first line, near the bottom, designates where you fill the soil up to, and the second line, way up at the top, designates where to fill the water to. It says to take your soil, filter out anything like rocks out of it, dry it out and mix it up good, and fill the container up Rating: 5
