Cheap mini-hygrometers for curing....

[MuskieMan]

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

[YYCannabis]

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.

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.

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.

Maybe I should order some on Amazon. I just chop my Kali China this morning now they are in the "dry room"

[MuskieMan]

I was pleasantly surprised that they are so close to each other...

Thanks MuskieMan Oh yeah I need some boveda also.

[DeadlyFruit]

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.

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?

[90Gizmo]

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
