Do not use water. Oxygen absorbers taped to the bottom of the lid work.

Thats a great idea. hadnt thought of that one.
still curious though why water wouldnt work or what problems it would cause?

Water will oxidize.
so water-H2O and distillate will create a redox-reaction? I would be interested to know the science behind that reaction. Could you explain that a little more for a chemistry ignorant layman such as myself? does the distillate/water contact cause a chemical reaction that involves movement of electrons, and if so at what rate? I was under the impression H2O does not oxidize easily which is why electrolysis is used to oxidize it. pure or distilled water is quite difficult to oxidize due to its ion content.

Put some steel in water. Oxidation.

thc/cbd distillate is not steel, if you put a peice of plastic in water you will not see a reaction like iron oxide forming with some types of steel. even then, if you used distilled water then this reaction doesnt take place.

Has that been your experience?

Youāll want to use a heavy gas like argon mentioned above

Well in his defence, you didnt answer his question you just told him to do what is known to work. But thatās not what he was asking, he seems to know that any inert gas will work to avoid oxidation so your comment wasnt helpful to his situation.
Dont take offense to it, hes looking for someone to bounce some ideas off of not someone to tell him what works.

Turns out you can make a lava lamp with disty and near boiling waterā¦
Havenāt figured out why one might do this, perhaps to deodorize?

Iāve actually tried to make a DIY lava lamp liquid system.
I ended up making a working solution from a mixture of various oils in my garage and paraffin candle wax. Took about 30 different mixtures till I found something that behaved the way I wanted it to. 
Now I want to add something thatās chemiluminescent.

So for argon do you spray in jar out lid on and then vac seal it in a oven? Or am I missing something?

Argon is heavier than air, so if your slowly āpourā it into the head space of your container you can just cap it.

Iāve used near boiling water to remove PG from a bad mixture of crude/PG. The odd effect of this hot water wash and sep. Funnel cleansing gave me some really nice single pass distillate.

@spdking seems to concur
I donāt see the need for vacuum and blanket gas I usually pull a vacuum on my Mason jars or use n2 for blanket gas but not both.
When long term storing food like rice and beans we would pop a piece of dry ice in our mylar bags let the co2 fill the headspace before we seal with an o2 absorber.
Anyway this thread is about the use of distilled water on top of your distillate to keep it from reacting to Atmos. We do this with guacamole and avocados to keep it green and not to oxidize.

Do you think distilled water in the headspace of a mason jar would have a negative effect on distillate? Would it help slow the color change from distillate oxidizing when reacting to Atmos?

yeah sorry. read your post & I added water to the jarā¦then for reasons I canāt fathom I decided to microwave it.
seems like it might be a win.
at least for that jar. 
as for protecting from oxidation, yes, it should keep O2 out, and I donāt believe it will cause you any major grief.
popping and sputtering on the nail might be an issue, but it should pour right off if youāre storing in the fridge.

Iām pretty lazy so finding a simpler way to store distillate is intriguing. Pouring a few mm of distilled water on top and throwing my distillate in the fridge is pretty fucking lazy lol. But I am opening this jar daily sometimes multiple times a day to mix various batches of vape orders

The microwave was an interesting addition haha
