    I bought 3 hygrometers from China. $2 each. Free shipping. Can't complain. These are so cheap that you all should by 3 of them and run them together to see which two read humidity the same. Also, you need to let these cheapo mini hygrometers sit for 6 hours. They actually read pretty decent. Within 5% if each other...which you can consider when you use them in curing jars.

    The above pic of someone elses hydrometer is too big for a curing jar, me thinks.
    The China bought ones are smaller.

    Will be using the cutting tool in the pic
    To install these in the lids of 1gal widemouth jars.
    Not my original Idea but I like it so I'm
    Stealing it.

    Overkill? Those cheapie mini humidty hygrometers from China are fairly accurate and great to toss into a curing jar.One can easily adjust for the differences if you put a packet of 55% packets in the curing jar, then wait a day and see how accurate your $2.99 Chinese bought hygrometer reads as compared to your 55% packet in your jar...then compensate for the difference.

    Anyways, I bought 3 mini hygrometers from China for $2.99 ea. For a curing jar. After 6 hours they all read pretty well within each other and my other hygrometer,

    The larger "mini" plastic hygrometers with "push button" are too big for a qt. curing jar.

    This pic may be of a "bad one." ??????? 26F??? lol. "So sorry".
    My three were good.

    I've just been using the small digital readers for reptile tanks. They're like
    You can pick them up off the shelf at just about every pet store on the planet for around 10 bucks a pop.
    They're accurate as can be and the batteries last for forever on them.
    Just dry and sweat your dope down to curing range. Make sure the RH level is stable. Slap a boveda in there and you're good to go.

    @charface
    Whatever you do don't drop those readers onto a hard surface. Wood floor etc. If you do then test the meter for sure with another one. I've dropped 2 that went all wonky and went off by 5 or so degrees. And we all know that 5 degrees too much turns into moldy dope.

    the caliber will fit in quart sized jars for sure.

    i agree it takes the cheapies a while to dial in.

    you've inspired me. bongsmilie:clap:

    i ordered wide mouth plastic lids for my quart glass jars.

    i am gonna cut out space in the lids for my mini monitors. the ones i have are designed to be surfaced mounted anyway. they have little plastic springs on the side.

    if i can cut cleanly with my dremel, mine should become mounted in the lids too and look professional. :weed:

    Im still on the fence for what to use as an adhesive/sealant.
    Not sure how tightly mine will fit
    Yet.
    Should be super close.

    Dremel sounds legit.
    If you look at the whole saw In my pic
    It has abrasive grit to do the cutting.
    Its from china so im hoping it makes it through 6 lids before it explodes in my face.

    The hard part is the tin is thin and will want to get crazy when you poke through. .

    If i might make a suggestion as a metal worker

    Get 2 peices of wood and bore a hole the same size as your dimond bit with a wood hole saw (dont wana ruin the dimand).
    Thast your center guide.

    Then clamp the jar lid in between the pieces of wood and drill carefully especially if the diamond bit doesnt have a center drill

    Then use a 2 part epoxy to bond it to the lid

    The bit will be fine but just dont let that tin do a helicopter on you hands it can get ugly fast lol

    Also move your dread locks outa the way
