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
