Haraella retrocalla potting?

[Zoey339]

Hi guys, I'm pretty much a orchid newbie with only the common orchid from the grocery store until recently. I've been doing alot of research though.
I recently purchased this orchid, Haraella retrocalla, in a jar. With expectations it would live 6 months+ before I had to repot it. Plenty time to learn. Well it came to me with mold on the gel stuff so it needs to come out. Please be kind I'm trying what I can for the plant. I want to pot it because I know pots, nothing about mounting and dont want to water constantly. I know it needs high humidity and I already got a fine orchid poxing mix and added moss to it. I reused the glass jar with little rocks about an inch deep at the bottom, excess water can drain into the rocks, with potting mix and plant on top with the leaves just poking out the top. I was thinking this would keep the humidity up. But now I'm thinking this will not allow enough air flow and the soil will be too damp. The humidity in my house is around 50ish%. Any advice?

I'm thinking I might have too much "soil" for lack of a better word. It's about an inch and a half. But it seemed like what I needed to cover the roots. I can post a picture later. I'm also thinking I'm over thinking all of this and I should just put it in a pot and water it every few days.
