After I did everything wrong the first time here is what I did today:
I put the flask in a plastic bag and used a towel to brake it. Bath: approx. 2L water + 1/2 cup sugar and just a spray of fungicide (no strong smell this time! LOL). In the tray I have orchid mix in the bottom and sphagnum on top. They will stay there for a couple of weeks until I receive the individual pots.
