Right? What is strange is that, regardless of the environment your harvest sits in it will eventually fall to biological and environmental processes.
The fact that the bag is permeable means that oxygen exchanges are happening. Oxygen, light and heat are what degrade weed.
To be able to preserve weed for that long? Seems like quite the claim. I noticed some on here have held product that long and they're reporting back that degradation was minimal so I'll use that as my signal to look into it and see if I get the same results.
Another thing that is weird, and maybe I just was too impatient and didn't find it on the site, is that when they talk about how long the bags will keep your product fresh, the narrator says that "anectdotal" evidence says that long term storage is maximized with their product. Why would he say that when they also mention hundreds of hours of testing? Again, not knocking the product but I do see some inconsistencies in their claims.
