I have found that I get the same results from doing the following, or so it seems, obviously I don't receive the plants I ship...
1. Trim plants, put into bag, blow some air in.
2. Trim plants, shake off, wrap in newspaper/paper towel with little moisture, blow into bag.
3. Upon request, trim plants, leave about 1/4 of bag with water in it, try to keep everything submerged, leaving not so much co2/oxygen so plants don't have a way to get out of being in water (not recommended).
I have had almost all good experiences, a few bad with each. I attribute most of my bad shipments (nothing dead, just rougher than the buyer/ROAK person wanted) to poor temperature and long shipping times. Think Christmas time (lucky this year) and summer heat waves. d
I personally like #1, from a seller and buyer aspect. It's easier on both sides, seems to be consistently good, and the plants just look better.
However, if someone is buying/receiving a ROAK, I tend to ask them how they want shipped. That way their is no issue in the end. If they don't know or care, I do my first way.
