These mini hygrometers work for you?

I fail to understand why people would buy devices that they admit are not accurate.

Only have 7 or 8 grows experience and found these to help me to not have too high RH% in jarring.
I still keep 1 in every 3 or so jars.
Once calibrated I find them to be quite accurate.

This small flat panel oil filled is the one I ended up with. 400W so it's not sucking too much power, but definitely enough for a small to maybe 5x5' tent. I have it hooked up to an inkbird controller. Its small and thin enough that it can sit in the tent and not take up much room either.

Which inkbird controller do you use for it? Good suggestion btw, reasonable price.

they do work for me.
takes awhile for them to adjust to a new space.
got at least a dozen of them for jars with no more that 2 or 3 points variation.
I will not spent 25-50 EACH for such a simple device that I need a dozen of.
theres another half dozen similar assorted temp and temp/rh meters with 1meter probes attached to the grow space.

I just use the heat outlet, not the cooling one. It's WIFI connective.

Thanks man. What's the upside of WIFI? The non-wifi is 33% cheaper

It gave me another bit of control without being home...You can adjust the trigger temperature and other settings remotely. That way if you find that you need it to trigger differently, it's easy enough to do from wherever.

Try replacing the original batteries. I had problems with those kind too but once I replaced the batteries they were fine. Those Chinese batteries suck.
