Cheap mini-hygrometers for curing....

Getting close to harvesting my plants... Picked up a bunch of mini-hygrometers to put in my mason jars to help with curing... Was pleasantly surprised at how accurate they are, between 50% and 53%. They even match up closely to the hygrometers that I keep in my tents... Is this the norm or did I just get lucky...

Those look like the same ones I have. I put a few of mine in a jar with a boveda 62 to test and in a couple days they all read 62 or 63
 
It’s not a coincidence 🙃 they kinda work. He best I’ve seen it’s xiaomi mijia Bluetooth hygrometers. Super cheap and much much more accurate and responsive than those black ones
 
I have the small round ones. And they vary +/-5% from each other. I put 6 of them in a jar with a 62% Boveda pack for 2 weeks and they all read different numbers.

If yours are accurate, i might have to ok into buying those.
 
Anyone know how long the batteries on the groboa ones (little rectangle) last I thought it was crazy it shipped turned on but now I’m thinking there’s little atomic reactors inside of them jokes aside they’re great I suggest everyone have atleast one
 
All my little ones (different brand) died within 12-15 months. But for all i know....they could have sat in a warehouse for 2 years before being shipped to me. Now i take the battery out when I’m not using the hygrometer.
 
Maybe I should order some on Amazon. I just chop my Kali China this morning now they are in the "dry room"
 
I’ve only ever had one die in the last couple years, from battery dying or anything else. I second that there is a mini reactor in the little things! My rectangle ones are all within 1 or 2% of each other.
 
Those ones look just like mine although different seller.

Like the cheap yellow pH meters, I bet they are all made by the same one or two companies.
 
No batteries required. Accurate for the last five years and counting.

I think I use the same as those and never had any issues. I only use them for the first couple of weeks of curing then once I’m happy with the buds i take them out.
 
Like YYCannabis some mine lasted about a year and a half, last fall ordered some batteries and replaced ones that were dying and returned them to service.
 
I just got a 10 pack from Amazon. Three didn't work and the others tested were way off in both temp and Rh. What brand did you buy and from where?
 
I've bought 2x four packs of the mini rectangles that were all spot on. These were ones that had the RH and the temperature numbers that were the same size. I bought a much cheaper per-unit twelve pack that had a much smaller temperature numbers. Two we're broken and ten were so far off as to be unusable.
 
I just got another 12 pack from another seller. Tested against my inkbird. All were so far they are going back. Please provide product link you purchased. Thanks
