Well, this'll be an interesting adventure.
Keep an eye out for mold, and remember that vinegar is your friend should it arise. If you keep an eye out and stay dedicated to opening it regularly to surface dry mold may be kept at bay.
I hope it works Oldbear. I like options, and being dependent on appliances and equipment can be a hindrance in some circumstances.
I've done one batch of fermented buds, and they came out right nice. I sweated them for a day, opened to check, then resealed and kept them in the hot box for a couple more days before opening them to begin curing. Mine were in a jar, inside a bag that was vacuum sealed. The paper towel in the jar absorbed any moisture that may have collected, but it was dry when I opened them.
You have to wonder how important the vacuum is when you're just doing the sweat to get a quick change in the buds, but having lost part of a harvest to mold once I tend to be cautious.
Those Amber jars in the sun may do the trick.
