I wish I had the facilities to hang and dry at 60 degrees, I'm stuck with room temp. I am considering buying a small wine cooler for storage of flower, though.As long as you dry them the way the directions tell you too, yes, they do basically take care of burping and curing. The way you do this is pretty easy though; They say to hang them for 14 days, at 60 degrees, and at 60% RH, and make sure the fan isn't actually blowing directly on the branches (it'll dry them out too quick) and once you get to that point, they should be ready for the bag.
Personally, I can hang them a LOT longer, because the back garage can stay really cool without being freezing, and the RH can be up a little bit, but once they go in the bags, they cure themselves basically. They are multi layered, to allow moisture in and out of the bag, to keep it between 57 and 63 % RH. In Winter, when Michigan is a cold Desert, you may need a humidifier though; The bag can't hold moisture if it's not there. I have stuff from this past season that's been in a bag over a year now. I haven't tried heat sealing them, because, yeah no... I'm not trying to heat seal a bag, I'm in that bag every day as it is LOL.
If they go in too dry, a moist but not wet paper towel can moisten them back up, and then you close it back up and leave it for a week or two, and it should be back to normal. I've had that happen a few times.
