My current PH testing solution is a real pain and I want to get a PH meter. Most seem like they have to be stored in a solution and calibrated frequently. Are there any that dont need to be stored in a solution, and or calibrated weekly? For my new setup I had planned on getting one that sits in the reservoir but I still need a PH pen for my veg area and I cant get one of those ones that sit right in the reservoir for that.
What do you guys recommend?
