My BlueLab finally arrived, and I'm stoked. I just tested it on a few pots and they all read right around 6.5. I thought my pH was higher, but I can finally stop playing the guessing game, lol.Ok folks, I want to hear what everyone considers to be their single most valuable tool for cultivation.
For me it's a reliable soil pH pen. You can check liquid pH and soil/coco pH.
These are the ones I use:
