I concur that Grove bags are pretty cool items to have if you grow.
I do a 2-part method that incorporates the best of glass jars and the storability of the grove bags...Basically, I hang-dry my plants for 2-weeks at 60/60. After that they get trimmed and put into glass jars with a humidity gauge and monitored for several days until the humidity in the jars is stable at ~58% and all the moisture has had a chance to equalize among all the buds. After that, I divide everything up into 1oz. Grove bags...HEAT SEAL THEM!! (bag sealers are relatively cheap on Amazon and it's worth getting one if you use Grove bags). Whatever is left over that doesn't add up to an ounce-per-bag, stays in a jar and gets smoked, first. By the time I get through the leftovers from the jars (usually a couple months), the stuff in the Grove bags will have at least maintained its flavors and terps -if not improved a bit!
Some people have used them, incorrectly, and put wet weed into them thinking that the bags would do the drying/curing for them.....and ended up with bad results. The advertising for them IS somewhat misleading in that respect. But, if you use them correctly, I think they are advantageous.
