CO2 for curing?

When I am curing bud in a jar, what is the best kind of air to have in there? Should it be high in oxygen or CO2? For example, once they have been burped appropriately, and are ready to stay sealed in the jars for long term, would it be beneficial to fill the jars with CO2? (I always have a tank of CO2 on hand that I use for a different application, but I could easily put a slow stream of CO2 into the jars and essentially fill them up since the CO2 is heavier and would force out all the ambient air)

u don't want any air in jars...air,heat,and light will degrade thc

Holy shit do I feel dumb. I just realized I can just put the filled jars into my vaccuum sealer (I have a professional chamber sealer for my other business) and remove all the air and also create the negative pressure required to perfectly seal the jar lids.

I wrote a long post asking how to get the air out of the jars, because I thought the regular canning method would heat the weed up too much, and allow in too much moisture. Then it hit me. Duh.

Sometimes I am not the brightest bulb in the grow room.

Thanks man.
