Well I’m for sure no expert when it comes to curing lol but thanks hahaha. I’m assuming you don’t have a small hygrometer to put in the jar, which is fine (I don’t use one) but means you just have to really pay attention to the moisture and maybe be a little more hands on. Seeing as you cut the buds off the stems already your gonna have to do sort of a squeeze test. I hang mine in a dark place and try to not expose them to light (it can degrade the thc, which is why curing is done in amber or dark containers usually) and do a bend where a bud is. If it snaps but not completely I’ll cut them off and jar them, if it just bends like a soft branch it needs more time. But for you it’ll be a little harder to tell, the outside of your buds will seem dry but the inside might not be. You can always add moisture to the jar keep in mind but if it’s too wet going in the jar you’re going to run the risk of mold occuring and you’ll wreck the jar.
Now to add moisture I just use boveda or integra 2way humidi-packs. 2 way is great because if it gets over 62% humidity it will draw some away if able. That really the optimal RH you want in the jar. So if you don’t use those, which some people don’t like to, I would recommend getting a small hygrometer off of Amazon or something and put it in the jar with the flower. If its under the 62 then I would just wet a piece of paper towel and put it in but find a way so that it doesn’t touch the flower or it might stick to it. Could find a way to fix it to the lid or just drape or over the opening and close the lid onto it. That you have to watch though cause it won’t stop raising the RH. You also want a jar that’s a good size for that you have. You want the jar to be no more than 3/4 full and I would say no less than half from my experiences.
I don’t see the 2 grams you got curing properly but it could. Like I said I keep mine sealed and in the dark. I burp my jars once a day (about 20 mins with the lid off) for a month, this is key for the air exchange, letting the plant release the remaining chlorophyll and allowing the inner terpenes to develop and come out into the plant. Then the second month I try and do it every other day. But that’s why I like the 2way humidi-packs because I’ve forgotten a couple times to put the lid back for maybe a couple hours lol…so once the lid goes back on it goes right back to that 62% and not worried about having to dial that back in. If you do go that route the size of the pack is key as well, they offer various sizes. I don’t go any bigger than the 8gram ones but I tend to use the 4gram ones. I usually have a variety of flower and concentrates to keep me occupied and from not smoking it all before a good cure. Not sure if I missed anything sorry for the length lol. If I think of anything else I’ll add it or someone else can add to it too!
Edit: I also spin the jars around until the buds start to move to rotate them around a bit after I close the lid from burping, just what I do lol
