You know, to each his own, but I would never do that to my buds. I don't think plastic bags are a good idea. It said in that little paragraph from some other site that a paper bag will work, wtf? The bud will dry too quickly, obviously! I use paper bags to dry, not cure. And trust me, a couple weeks in a paper bag and your buds would be a crumbly mess. Again, just my experience.
Ya OBVIOUSLY it said right in that paragraph why paper bags are a bad alternative, because the buds will dry too quickly. You pointed out nothing. And many people put their buds in sealed paper bags between the drying and curing process because it is sort of like a quicker cure (in order to avoid mold or rot),
IMO unless your a judge at the Cannabis Cup or the like, your probably not going to notice a huge difference between curing in plastic vs glass. If ziplock bags are the only thing available, then by all means just use them to cure, BUT not for long term storage. Cure them for some weeks, and if they seem to be getting too dry too fast, then make the switch.
