I need a hygrometer / humidity meter - what do you recommend

[VolimPicke]

When drying my harvest, I need a good (but not expensive) humidity meter.
One that can be put in a jar for final curing.
What do you recommend?

I see these, but do not know if they are good.
The old adage says "you get what you pay for"
It says for humidity accuracy of ±5%RH.
but... I wonder how accurate the analogue humidity meters are
At less than $4 each, they are quite cheap.

the ones ive bought are similar. no problems but they arent perfect. 1 failure out of a dozen in a couple years.
buy a few extra and get them for even less.
some include extra batteries.
got a couple with 1m probes for inside the grow.
simple electronics stuff has gotten so inexpensive

To be honest you don’t really need those. Yes. I bought them too long ago but they did not actually help with curing. They did tell me that I jarred too early but once you know that your buds will already be harboring mold. Then they will turn brown and smell like old sweaty socks and eventually ammonia. Hygrometer will not prevent this …will just make it visible once it is fucked.
I suggest allowing your buds to dry completely; that means to wait until the stems snap before sealing the bud. Hang for at least a week and then check the stems daily for brittle-ness. If the stem bends over and crease without a snap there’s still too much moisture locked in the bud to seal it up. No need for burping the jars or using a hygrometer; let it dry completely and seal.
Leave the lid on your jar on loose until your are sure the bud is dry enough. Next day put your face in the jar and get a good whiff; of it smells like dank weed you are fine to seal the jars. If it smells like hay it’s moldy and needs to dry out more. This imo can be harder for a noob to learn than it us actually growing the weed. Growing is the ez part

I read that 60% humidity is ideal.
Being very dry will prevent mold but being too dry affects the taste.

I see that even a more expensive unit gets ±3.0 %RH

its a tool, don't blame it for a failure.
use the info it provides to make decisions.
if you jarred too early it'll show within a few hours.
you can get a physical feel of the buds texture so next time you'll know to either let it dry longer or shorter.

 

[VolimPicke]

As a noob, I need concrete datapoints to make a decision.
You are an expert and have the FEEL for it.
You can't advise me to develop a feel for it overnight
when it took you many years to develop the feel.

There must be a reason why many places say that 60% humidity is the ideal level of drying

Nothing wrong with using those little meters. Any cheap ones will do. Put them in an empty jar with a bovida pack to verify they all read about the same, discard any that are off. They are cheap devices so not a big deal. 60% is the number you should be shooting for. I see others giving advice on just going by feel and whatnot but don't sweat that. They are correct that you will not need those meters once you get a feel for things but while you learn there is nothing wrong with having some help in guiding you. Eventually like some others here you will be able to tell by the way the buds feel, that just comes with experience. Experience takes time. While you are getting data from these meters take the time to feel your buds and see what they are like at different levels. In time that will teach you what you need to know. Good luck.

No you don't.

I like data.
data turns into knowledge.

The most accurate "jar size" hygrometers I've found are Inkbirds. I have several and they all match-I'd check them out first.

I hear good things about the Inkbird ones. There is actually a medical company selling them in lots of 6 on Ebay for $12.95 each so cheaper than anyplace else. Be a good source to get them cheap.

just an example.
I have a bunch of similar ones.
$2 per is less than I paid!
plenty accurate enough IMO.

these are handy too.

Has anyone used this sort of hygrometer?
A bit more expensive but seems better quality and more accurate @ +/- 1.8% than the Inkbird units.

The Inkbird models on eBay are used and seems the battery is dead.

Inkbird has an amazing track record. I have never heard of Diivo

This is true, it says so in the ad as they need them in their shipments coming in, that's why they are less then $2. Bulk batteries for them would be super cheap if dead. The issue I see with the ones you posted a link to is they are way bigger so would not fit well in many of the jars folks use. They would work well in a tent and log data for you so that could be a bonus.

Thanks for the heads up!

I ordered 6 and they arrived today. (Actually they also included a bonus one)

The 3 different cheapo ones I ordered in the past did not come with On/Off switches. These did. They came with the power off and I fired them up. All started quickly. I have no idea how long the batteries will last.







My purpose for this purchase was for the Hygrometer.. Hmmmm.....

I use Govee hygrometers and generally love them. They're pretty accurate, very cheap, and if one drifts a bit you can adjust it in the app to get it back in line.
The app is pretty decent and allows you to export the data easily.
Biggest complaint I have is if you buy the cheap ones, their batteries die about every 3 months (faster if you forget and leave your phone paired to it)

Cool,.glad that worked out. From what I understand they were used to transport once and then I imagine they turned them off but cheap batteries are easy to find when they do die.
