New poster here, been lurking for a little while. Quick question concerning using 02 obsorbers/vacuum sealing, haven't seen this addressed. If I am able to use a vacuum sealer to vacuum seal a mylar bag, would I still need to use an 02 absorber in the bag? I am thinking so, since no matter what I am sealing(thinking grains) would still have small spacing between them, correct? Thanks in anvance.
