Hey guys I am in need of a really cheap but effective PH meter. My old one no longer calibrates therefore is no longer reliable. By cheap I mean like 50.00 or less sp if you can help me then TYVM. I was checking on the Hanna Checker but not sure about reliability.
Also for my small closet grow I use a 5 gallon res. I check the PH 2 x daily but I can see that my PH issues may not be my water at all. Hey fellas can I get some good tips for checking PH too. I am mostly self taught so I am not sure if my methods are the best methods.
