Is it possible to check ph level from soil by watering the soil and useing the whater that come from the bottom of the plant? or do i have to put some soil in the test tube?
had a little something like that but it necer seems to read the ph well! so i went a got a liquid solution ph tester. Ive used these solution test before just thought that i could do it with out sticking soil in to my PH tube.
