Nancy, you need to update your profile with your location. Sphag & Bag is fine any where, but potting up without roots I would only recommend for high humidity areas like Florida. The bag you have is fine. I usually hang my bags from the edge of my greenhouse bench. The hormone thing is fine for a rootless plant as it will act to start new growths, but you have to wash it off after the new growths start of it will act to delay rooting in the new growths . I know this sounds crazy, but rooting hormone on Sympodials, at least on the rhizome does not stimulate roots, just new growths. This from a year or so of experience in using a variety of rooting hormone brands on a ton of plants.
