Try a freshwater aquarium ph test kit. Will give you a good idea where your tap water stands. It's color-coded results won't help much with run-off ph, nor after adding your nutes.
Rusty Trichome Reviewed by Rusty Trichome 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
