Attic Storage

[bloocrab]

I recently layed some Advantek up in our unfinished attic space to create storage space, not living space. (60 sheets actually...ouch, my back)
So as not to decrease my R-Value, I had to raise it up a few inches with cross members. The insulation type between my ceiling joists appears to be blown in wool/stone/fibres? It's grey fluffy stuff...sorry, best I can describe it.

Here's my question, have any of you tradesmen seen mold build ups beneath attic flooring in an unfinished attic space?
I just want to know if I should be concerned about what I did...I didn't block any soffit areas, nothing to stop or impair circulation...I just didn't know if trapping the insulation between the Adventech and the sheet rock would cause issue? There is a vapor barrier (poly) between the insulation and the sheetrock, not sure if that helps with your opinions?

I did do a lot of research prior to the project, but experience supersedes any research that I could ever do...
