Small hygromerter

[dj1714]

Can anyone tell me where you can get the small hygrometer that will fit into the jars when curing? I have seen them in some pics here on the site but can't seem to find them anywhere. Harvest time in 6 days and would really like to have some in the jars.
Thanks.

I use exo terra hygrometers. Need to calibrate them before use.

Are they pretty accurate.

I have 4 and they a between 1 and 3 points out. Just take a bottle cap and fill it with salt. Then add some water so it is like wet sand. This will give you a humidity of 75%. Put it and your meters in a sealed container or ziplock bag and leave it for 24 hours. What ever the meters are showing after the time is 75%. Job done.

Thanks for the reply Cheese. I'll take a look at them.
