Mini hygrometers for curing

[JWPcinders]

Hellllo, so I bought this 8 pack from Amazon. I took them out of the pack and they were all reading relatively close. I put them in my dry room where I have a hygrometer reader on my inline fan. I popped one of them in a container of weed I am curing. But the % doesn’t seem to move lol. They move a little but not much. My dry room inline fan hygrometer says it is 60% and the minis all say something different. Heres some pics. Any suggestions with the didferences?

How long did you have them in the jar.

How long did you have them in the jar.

The one in the container has been there for over an hour

Give 2-3 hours and see what it’s reading.

Penny may know this but someone was telling me the other day you can put a cap full of epsom salt in a bag with the mini hygrometers and they should read 72%... I did not bookmark that so I’m questioning my memory if 72 was the right number....

also JWP, that looks lIke the settings screen for a cloud line fan.... which is very nice but is that the local rh shown or the rh from the remote probe inside the tent.,? Just checking

The small hygrometers are all within 3% +\-

Yes somebody said you can verify with a soda cap full of epson & plastic baggie... now I can‘t find it

Just seen some nice jar lids posted by @SeniorMoments on @Lilnuggs thread

I don't like my meters getting all sticky ,laying in the buds.
So I use old school jars with glass lids & rubber rings. Then I use sticky tape to hold it to the lid

There is no tent it is a room in my house. And the probe is in the room.

Here is an update from this morning. I guess I over dried that first stuff a little bit? So many different readings lol

I have the same style cheap Chinese molded plastic takes hearing aid style batteries.... I’ve seen 420 user Senior Moments has really nice ones that are made into lids to fit mason jars and they have analog scale like a meter. There are other style out there but I foolishly jumped on the inexpensive one from the Zon

Hygrometer See pics at post #4

Calibration works with most types of salt. A few teaspoons of salt in a bottle cap just moistened with water and put in a baggie (with meter)will read 75% once it reaches equilibrium. This will take 24 hrs to get an accurate reading.
I may have bought the same set from the zon and had the same issue.
I'll be getting some adjustable analog types in the future.

Hey Doll, I agree wholeheartedly... did you see the ones from the link? I love the analog jar lid version!!

 

[bluter]

i use the cheap plastic analog ones. they are always out a bit. i make note of where they sit against a digital meter, and just keep that in mind while curing. they're hardly a couple bucks each.

Hey there Tiger
I almost bought some on Etsy but they are $12 a piece. Maybe later on when I'm rich and all powerful!?!
Perhaps I can diy my own?

Inkbird makes fantastic ones, but they are pricey at 12/pop. Incredibly reliable tho, I bought 12 of them and the difference between the highest and lowest was 0.4 degrees and 2%

 

[013]

Yep, yep that’s me... tigers are always on the prowl!

Yowza that’s pricey! They should offer to cone burp your jars for that much!

Think I should get a humidity pack for the stuff I have in the container then since its only setting around 56%?
