Never tried that but I'm not so sure there would be any advantage, and may well increase the potential for mold and such... after you remove it and it thaws you won't really know how much moisture remains in the plant material....because how are you going to measure the humidity when its in the freezer?
I do freeze my cured bud after 3-6 months and it works great. no decrease in potency. I vacuum seal in heavy bags and then put those in large canning jars tp prevent crushing the freezer bags. When I take a bag out I let it warm up to room temperature before opening. You need to handle the bags carefully or you can knock the trichomes off easily when they are frozen.
I do freeze freshly harvested green sugar trim and popcorn buds in freezer bags when my intention is to make bubble hash. Fresh frozen is the way to go for bubble hash, especially with really frosty stuff. First run usually results in beautiful golden translucent chunks in a "sauce" which take on a crystal appearance when dried correctly. Maybe my favorite smoke. Super terpene flavors.
Cheers
ps; When I take the fresh frozen out of the freezer bags to make bubble hash, even if it's been in there for a month, it shows no signs of curing once it thaws.
