best hydrometer for curing

I sure just about every one uses some type of hydrometer to tell when to burp their jars, last harvest I bought a few cheap digi ones but they are all over the place! and when curing 5 and 10% can make a huge difference!

I don't mind paying 30 bucks for a good one, but I'd would need at least 4 or 5 of them, and that's getting expensive! there has to be a cheap and accurate humidity reader, I don't need anything else from it, except the rh% and for it be accurate within... I'd say 1% or 2% at absolutely worst case scenario!

what do you guys use? mind posting a link if you have something you would highly recommend, I'd really appreciate it! happy growing everyone!

you don't need 4 or 5 of them. just compare your jars with each other, and move the hygrometer around. that's what I do... well did. I don't use one anymore

and its hygrometer, not hydrometer

i've never used this one, but i use their humidity controller for my gourmet mushroom grows. they make a nice product and this is pretty affordable

lol I swear I didn't know that, dam I wonder how long I've been running around sounding like a dumbass! well thanks for setting me straight I appreciate that, who knows how many ppl have been laughing their ass off at me for that, and not told me a dam thing!

if this thing actually works and isn't bullshit than I think I'll be in love! and it's only like 20 bucks!

been looking and haven't found a single negative comment, hopefully I can find someone who has personally used it!

Caliber IV is the standard by which all others are judged. I have many hygrometers and most are very very slow reacting (and barely accurate). The Caliber IV's react in about 1 minute.

When I buy new meters , I will take 62% packs , and seal them in the bucket, then compare. The ones pictured are usually only out 1 - 2% . Then write + or - 1 or 2% so I know.

this is also what i have

I bought these at the local petco and I used a boveda calibration pack and most of them are dead on. Youll get one that is off though. Better to buy them locally because online theyre too much. I got 5 for like $5. They adjust fairly quickly too.
