I need calibration solutions so i can recalibrate my soil ph probe but if i am gonna spend $20 on solution i may as well spend $50 on a pen that comes with solution! Win win! I will order storage solution tho cuz my probe comes with a tiny eyedropper bottle of drops for storing it!
It comes with enough fluid for a while. I check it every couple weeks. Then all you really need to get is the 7.0. I've never used storage solution. I check my ph every day and it never actually goes dry unless I forget to put the cap back on. Then I'll recalibrate and it'll be off like 0.1
I also had a ph meter go bad on me. I bought new calibration fluid and a new cap from Amazon to make sure. I sent them screenshots from the purchases and they sent me a whole new meter
I found a copy!!! Its literally cover to cover the whole damn issue is about cannabis! Oh how for we have come. Who wouldve thought? Boris ad i are on the train headed home, should be a good read!
