Welcome to Orchid Board
I agree with Wynn, except that I think if it is taking more than 2-3 weeks to dry then that is too slow and could indicate the moss is too tightly packed or too decayed.
In fact I generally think it should dry in arround 7 days, 14 days at the absolute outside. I mostly grow in bark, but I've found whatever the mix if it dries slower it indicates not enough air getting to the roots.
I would take a look at the roots, pull it out the pot and pull some of the moss away. If the moss doesn't look decayed then you can put it back in that, but don't pack it too tight. You'll probably be amazed just how much moss was in there, and usually they are sold too tightly packed.
If the roots are in good condition (firm when you gently grip them between your fingers) then just put it back. However if they are bad (hollow or mushy) then there is a problem that needs addressing.
Post photos here if you are unsure, or if they are bad and you need further advise.
Bud blast like you are getting could be just from transfer from the nursery to your home, but it can also be due to root problems, so it's a good idea to check those.
