Cure jars

[charface]

I see no reason why i cant use a hole saw to cut some large mouth jar lids
And mount these in the lid.

The air vents will be in the jar and the face outside the jar.

Anyone tried it and discovered an issue?

Planning on 1 gallon jars

The only downside i can predict is jars wont stack and i will have to wipe the lids off with iso or something instead of washing them.

These things are pretty cheap so i worry that they are inaccurate but i can always get better ones

I did these a year or two ago, work well, no issues

Nice, I thought i had seen some but wasnt sure if they were diy.
I have mine all out sitting beside a digital and surprisingly they are fairly accurate. Ill give it a few hours and place a mark so i know how far off each one is.

Great idea, I will try these on 4 or so jars. Thanks

Found this, it is 60mm like the gauges.
Looks like a good $7 remedy.

I use the caliber iii i believe small hygrometers. They fit perfectly in quart jars.

I had an even smaller one with a magnetic strip and mounted it on the underside of the lid. It died quickly though so I didnt reinvest in the brand.

I dont even use it anymore. It was good when I was a beginner, but I judge by feel now.

I do things by feel too but i think i can do better sometimes. I just like the idea of not guessing a couple times.
I think this whole project is just probably another way the universe is saying I have too much free time.

Those are amazing do you remember the brand of hygrometers and any chance we can see more pics like under cap and arethose rubber gromets or just a plastic flange

Found the hygrometers how long does the battery last on one of those and did you just silicone to the lid?
