I'd like to start by discussing Cheap ph meters, people say a lot of bad stuff about cheap ph meters ( i have the yellow one thats sold everywhere and goes for around 15 usd)
People say they're inaccurate, but I've had mine for 1/2 years, and it's always been accurate with monthly calibration.
Is it the most precise? No, but do we need accuracy within 0.1 for most growers? No, and the margin of error is around 0.1 on mine
Now, i wanna ask something to the experts, everywhere on the internet i read that the probe is usually done for after a year or 2.
Yet mine is still working without problems, and it's a cheap ass meter... My hydroshop guy told me that probes don't actually need to be changed every year, so a bit of conflict info there .... What do you guys think?
