I haven't got enough experience with this- but the people doing the vacuum cob technique claim that mold will not grow in vacuum.
I'm pretty sure so long as the weed has been dried to the desired humidity level before sealing you won't get mold.
I 'll be curing by sweating the just-dried herb in vacuum until i reach the desired consistency, then re-vac and store in low temperature (not freezing). The mason jars with Foodsaver sealer seem like the ideal solution
For now I bought some plastic Foodsaver tubs and was happy to find my cheap-ass Silvercrest vac sealer has a compatible nozzle so I'm already vacuuming away!
Re: burping- i think if you let the fermentation continue the hay/ grass smell goes away as the chlorophyll degradation proceeds.. this is what i did last summer and the bud did not lose its original aroma after sweating in vacuum for 3 months... The buds looked noticeably darker. It did seem like a more pleasant vape and easy to crumble without a grinder.
The cob technique looks interesting. I'm eagerly watching to see how it works for you, and would try it. When things calm down, I'll read about it. Thank you for introducing me to the concept.
I wash, trim, dry, jar, and usually burp my jars initially, but half I didn't burp. I use quart jars, and they go in large plastic tubs. I have 4 tubs, so I figure I have 3 months supply in each tub. I keep 3-4 smaller jars at my station that I fill every few days. Small and quart jars have Boveda or Boost, and every third jar has a hygrometer. It's getting to be Spring, so the tubs are going into the root cellar minus an arbitrary number of jars I'll keep close at hand.
This year wasn't as hot when I harvested, so it took 7 days for the dry, but I had humidity to contend with. That was different, but not a problem.
Boveda goes in my kief box as well, and when I press my kief into pucks, I put them in a secure container that I set aside, and can never find again. They can't have walked off, so I know they are around here somewhere.
Rosin gets stored in the refrigerator, but I might be able to be convinced to spend a ridiculous amount of money on a rosin cooler if enough people tell me I'm ruining my life by putting my rosin in a refrigerator.
I keep infused butters and oils in the freezer. Tincture and infused sugar in a cool closet.
I've managed to get a dozen jars sealed so far, so I am plugging away at it. It's a good idea, I just like to resist a bit when good habits introduce themselves. I long to have a rebel soul.
