I use those - the ones that fit inside a jar lid right? They are great and for me they have unlocked the secret to a good cure which is to let them hang for longer. Use a enclosed space (a grow tent works awesome) to hang for 10-14 days if you can. Then jar your buds...if the next day your meter goes higher than say 75% RH you've got to let them air dry for longer- takes about a week or 2 but you'll eventually get them down to 62%. Then you can use your Boveda packs to keep them stored at 62% without burping but the packs themselves do not cure; they are for maintaining proper moisture for long term storage
