Repotting NOID Phals

[moongirlz]

So, Ive got some general questions on repotting Phals. I realize that some of these questions have most likely been asked and answered before, and I was directed to the thread "The Phal abuse ends here", so Ive been going through that. I probably shouldn't have stuck to just that, so I apologize beforehand for asking questions that many people before me have asked.



I have a regular sized NOID phal that was a gift, bought at a Trader Joe's. Ive had it for two and a half weeks, and roughly a week ago I noticed that there was mold growing on the roots and medium(bark) at the surface. I've left it alone since, and have ordered orchid mix from repotme.com
The orchid is currently in bloom (and actually looks a lot better than it did the day I got it, save for the mold growth). I know you're generally not supposed to repot when the plant is blooming(and/ or repot immediately when you get the plant. I didn't know this previously).
I'll be repotting it in a few days, because of the mold. Are there any precautions I should be taking, or specific steps I need to take when repotting this Phal?

Then, my grandmother also has a few Phals herself( a total of four), two of which I inspected today and have root rot. The other two have a good number of aerial roots. One of these has four new roots coming in. The last plant has a spike that has started growing. We were also planning on repotting all of these, due to the fact she's had them all a few years. Is it safe to repot the Phal that has spike growth, or should we hold off until it finishes blooming? (The spike is about one centimeter so far, maybe a bit more)

And does anyone have experience with mini Phals? Ive got four, all of which I wanted to repot as well because they're packed pretty tightly with moss. The roots of all of them are in good condition, and three of them are in bloom.

I've only just gotten more into being more involved with orchids, due to my newfound attraction to the miniature ones I've seen around and bought. I apologize again for this massive post.

Any input will be greatly appreciated!! Thanks
