55-62% is a good range. Some people prefer the buds a bit drier and some like it a bit more moist. As long as you are at least 55% you avoid fast(er)-paced deterioration of the buds. Going much over 62% raises risks of mold.
When curing you want 3/4th full, but once fully cured you should fill up the jars as fully as possible. Less air is good for long-term storage. It's only a problem when the buds are still gassing off some moisture in a sealed jar, albeity small amounts.. it adds up fast in a limited volume.
The bad reviews of boveda are about uneducated perceptions. First, what you smell is 'lost' from the plant, not saved. So, less smell emanating from the buds means a slower loss of terpenes and whatever else causing the aroma. So, the common person that doesn't understand that thinks the lack of smell is a negative, erroneously, and good luck trying to convince some obstinate kook of anything smart, lol.
if you smoke your stash within a few months, you probably don't need a 2-way humidity pak or anything else extravegant beyond a sealed jar to maintain your weed. longer-term storage will not maintain a proper RH simply from plant material in the jar. you will want a 2-way control pack - as others said, boveda gives you what they advertise, but integra boost is total trash that won't maintain an RH% anywhere near what is advertised. My boveda packs are +/- 1%, like clockwork, on the other hand.
most problems from boveda packs are due to mis use. they can only absorb so much moisture - simply weight them and if they no longer gain weight that means they can't absorb any more moisture and if using with moist buds it will do nothing to prevent mold at that point. so, user-error is the problem 99% of the time with boveda packs. Don't think they allow you to put wet buds into a jar and forget it, lol.. still need to properly dry them, first.
if you don't want to use them, get a vacuum sealer for anything long-term.
Have a storage container and a personal smoke jar. this way you don't open up the storage container everyday and exacerbate the loss of moisture over time. the primary storage after a proper cure should remained closed. to prevent anaerobic growth you may want to open it up once every 2-3 weeks, though. O2 deteriorates thc, but anaerobic bacteria turns it brown and makes it taste like schwag. so it's a damned if you do or don't situation.
