I keep hearing different things from people about when you test your ph in your water. Is it before you put your food in ??? or after ??? Also should you be using some type of a meter to be checking the ph in your soil????
HIGH All, I check the PH before and put PH down to get to 6.5 after I check to see the run O.F.F.F. I use Hanna PH and TDS meters. I use them for my Hydro. Soil pens work but aren't to reliable. Any would work and I think a must.
