I bought myself a little New Year's present, but I need some advice/tips on what to do once it come. It's a Phalaenopsis bastianii in a 2.5" pot. It's being mailed with a heat pack. The seller recommended I water it as soon as it comes, due to drying from the heat pack.

Assuming it looks healthy what should I do with the little guy. Nothing? Re-pot?

If it looks poor I know I need to take it out of the pot and see what's going on with the roots, etc. If there is rot I know to clean. Should I use sulfur or Physan 20 or hydrogen peroxide?

What medium should I use if I re-pot? I have medium and course bark mixes. Should I water it?
