Do I need to wait for a Snap, or go ahead and start curing?

You can wait a few more days. 15 days is the minimum I let my buds dry. In the next step, I manicure and place them in glass jars without filling the jar 100%, leaving some space for air circulation. In the first few days, I open it 1 or 2 times a day for air renewal. Good luck!

a stem snapping depends a lot on the size of stem you are trying to snap. you can begin cure, then check on it 6-8 hous later.. if the outside is again soft and clearly moist, pull out -- how long relative to how wet it is, then repeat that process. 2-way humidi packs make it easier, but they do have limits as to how much they can absorb - can weigh them and find that point.. integra boost sucks. don't use that brand. RH never matches what product says. i put 12 67g packs in a bucket that requires 2 to 4 packs and they still don't do a good job. boveda is far superior brand of the two. their 55%-59% (i forget what it is exactly) and 62%. if you like things a bit stickier, do the 62. i wait for the outside of buds to feel dry, then i wait another 12 hours o rmore to put them in curing buckets. even then on occasion i have to pull them back out due to excess moisture. If unsure, just make sure oyu check on them intermittently that first 24 h.. make sure they don't get 'soft' which indicates the too much moisture. They shouldn't stick together too much -- really good weed is sticky, but there's a difference.

Boveda or other company 62.5 packs will rven out, but after 12 days with your size no snap its strange. Slower is better, so you in win area ...

A easy test is grab a bud and pull it down on stem. If it snaps or breaks your ready.

You should be able to gently pull the bud away from the stem without needing to snap the branches. If it easily snaps off, then it's ready for curing 🍻
