Did some repotting with Phal mix and Moss - some questions

[glitchathon]

I finally got my order of NZ Sphagnum Moss and repotted my Costco Orchid. I am glad I did it as it was so tightly packed with wet moss and the roots were starting to rot.

I did a mix of half Moss and half Phal mix (Better Gro brand from Lowes) to help it drain better.

Just wanted to ask a few questions on repotting:
- Is it best to keep the media loose? I put in the bark and moss to just fill in the gaps of the roots as best I could. I did not use any pressure packing anything in. Looking through the clear plastic, the media fills up the pot nicely but with plenty of air for breathing. Is this generally the best way to go? Was Costco's method bad, in which the moss pretty much is packed tightly with the roots?

- How resilient are Orchid roots? In order to seperate the roots and cut off the rotted ones, I felt like I was stressing out the root system. Some of the good roots split/broke but I just put a little cinnamon in the "wound" and left them intact.

- Next time I water them, should I use Dyna Gro KLN?

- I have a lot of leftover Sphagnum Moss. What is the best way to store it? I have it in a regular tupperware container right now.

Thanks very much!
