Do those work in both water and dirt? Are they accurate?In all honesty? I recommend simple litmus strips. Digital Ph meters are all good n that, but most are stored for years in warehouses and need calibration to be accurate and calibration can be a hassle. And then theres the solar paneled 3-in-1 meters you see on eBay, they are complete crap and most of them the ph reading doesnt work. Not to mention litmus strips are cheap as chips.
What is calibration? And how do I do it?calibration is simple and those strips aren't very accurate.....
They work in liquid but i doubt dirt, they may not be hugely accurate but they are accurate enough to get the job done for measuring liquid.For me calibrating my digital ph meter was annoying because the room had to be in a certain temperature or the ph calibrating liquid wouldnt be the correct ph level for calibrating, i think it was boron somethinDo those work in both water and dirt? Are they accurate?
I looked them up on ebay, 160 for like 4 bucks lol. Definitely my style.
Listen to this poster 100%!!! Even $3.99 is $3.99 wasted. I have a $13.99 version of this device and IT'S total CRAP!!!those are junk, you need one for your water not your soil...
