Vacuum canning a gallon mason jar. Possible?

I am putting together a commercial grow and I was curious if there was a way to vacuum seal a 1 gallon 128oz glass jar?

We plan on curing 8oz of product in the mason jars then vacuum sealing them once they reach optimum humidity for storage until they sell at wholesale.

Thanks!

Just get some Boveda packs

Yes, you can. There are even packaging machines commercially sold that will purge your package with nitrogen before sealing. On the consumer end, you can buy gizmos that sit on top of the jar and lid and suck all the air out. The same companies that sell vacuum bag sealers sell the gizmos.

A nitrogen purge, btw, will give your product a verrrrry long shelf life.

It's oxygen that is the enemy of plant matter.

Do you have an example of this type of commercial machine? Nitrogen sealed in 128oz glass jars would be perfect.

Here is one just to give you an idea how they work....

Do you know if its possible to do the same to a 5 gallon food grade bucket?

I would have to believe it is. The companies that sell "survivalist" food stores all claim they nitrogen purge their food stocks.

You probably need some kind of plastic film you can seal over the top, similar to what they put on the jars in the vid. Either that or a top with a really good seal and a couple of gas ports you can run N2 in through and let O2 out from.

Just be sure to use food grade/USP N2. You don't the industrial stuff with oils and other contaminants.

a humidor would work just as well, and be a lot easier to get ahold of. if you're that into it, build a walk in humidor, just install a humidistat and a thermostat, keep the area at 65 degrees and 62% rh, shit should last for years

Beware of elevation and pressure changes that can cause exposure/leaks.

i live in the mountains, you can buy marshmallows in town, drive to the top of the mountain, and they're twice the size.
don't expect you to have that big a differential in your house, but transporting it could cause problems
