Stuntman Mike Posted January 24, 2019 Share Posted January 24, 2019 I'm growing organically outdoors in 40L fabric pots, but have not been PH adjusting my water. The plants look really healthy so far, but I'm worried the PH buffering the soil (freedom farms) provides will get out of whack eventually. I have a Hanna PH/EC pen, which I got probably 15 years ago. I stopped by their shop in Bellville yesterday to replace the PH electrode and get new calibration solutions and they quoted me R3555. . So what do you guys use to measure your water PH as I'm not spending that much? Also, I have been using tap water left overnight to leach out the chlorine, but I also have loads of rainwater in my jojo tank. Which would be a better source to use? I always seem to remember the CT water being close to 8 PH. Thanks. 1 Quote Link to comment Share on other sites More sharing options...
Dr. Green Posted January 24, 2019 Share Posted January 24, 2019 I bought an H&M ph80 for like R900 from futurama. I does PH to 1 decimal and temp no EC. Quote Link to comment Share on other sites More sharing options...
Jimmy-z Posted January 25, 2019 Share Posted January 25, 2019 I got these from takealot a while back. Cheap, but it works. I tested our tap water, & both the pen & drops confirm 6.5Sent from my SM-N950F using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

Stuntman Mike Posted January 25, 2019 Author Share Posted January 25, 2019 Thanks for the replies guys. I might go with one of those cheapies off takelot. The EC probe is still totally fine, so I can still use my old one for that. Quote Link to comment Share on other sites More sharing options...
