Looking for what everyone is using, for ph, ppm, and humidity. Don’t want to waste $ on product that’s not accurate. All suggestions will be appreciated!

Apera PH 20
I got a cheap Amazon ppm meter.
The PH meter is what you want to spend a little bit more money on. Good luck!

Like @HappyHydroGrower I used the apera 20 and a cheapo tds meter. pH is a logarithmic scale so you want to be very accurate. Make sure you get calibration standards!
Other brands I hear were good are blue labs and Hanna. Not sure if I spelled them correctly but a google search will tell you😀

i use the apera 60, what ever you get make sure it comes with calibrating solution. and i agree… i used a amazon ph meter for my first grow…and a few ph issues…got the new meter… new meter would read 6.0 old amazon meter would read either 5.5 or 6.5. thats a huge swing. a accurate ph meter is worth its weight in gold

The only one I’m really concerned about is the skywalker. What do you guys think?
Maybe it is the strain? I’ve grown two and both of mine were temperamental.

Thank You! I’ll be patient then.
Ok got my apera 60 been measuring everything lol! Is anyone using 100 lemon juice to ph down?
I haven’t but heard it works
I’ve used it and also white vinegar. That was in super soil but I’m growing in coco now, so I’m upgrading my pH control system.

@Rowdy , I have an Apera pH pen kit on order cause the seeds are sprouted and transplanting in coco is only a few weeks away. I have a TDS meter from on top of a Zero water picture, it works.
Here is my pH meter, no batteries, never needs calibration, always reads correctly unless you are colour blind.
