That's what I use and it works great.I went for one of the handheld manual vacuum sealers for jars ($17 all in) and it has been working great making tight seals after about 12 pumps.
I use this jar opener to remove the vacuum sealed lids from the mason jars. It has a wide contact area and works well except for the strongest vacuum seals and even then I can remove the lid without damaging it. It is not designed for this specific use but it works fine.That is why there is a special tool available to help pry open but it tends to ruin the lip of the lids.

When I want to adjust the humidity I place the weed in a 2 gallon Anchor Hocking glass jar and place a small open jar of water inside.
