Coco is the same as hydroponics so shoot for a ph that swings from 5.3 to 6.3 that way all nutrients are uptaken. Also don't forget to add a calcium supplement like garden lime or cal mag from botanicare or whatever brand you like. **Q: Can you read nutrient solution PH with this as well?** A: Yes, it measures both soil and liquids. Gives the temp and pH of both. **Q: Can this device measure PH of soil outdoors?** A: Of course **Q: Do you sell the glass with sensor replacement for this soil ph pen?** A: I’m pretty sure that it’s a one time pen unless you get the other unit with the replaceable heads ## Customer Reviews ### ⭐⭐⭐⭐⭐ accurate and fast *by W***N on 29 October 2020* bought this for my Wollemi Pine that needs acidic soil that is slightly more acidic than the brands of soil you get at local garden centres.
