VEry unexperienced bulbo grower... help?

[JKeys]

I just bought a bulb. echinolabium. I potted in a mesh pot with peanuts on the bottom, and placed in the plant so no pbulbs are covered, then put in some sphag. The plant was previously in... potting soil? Many roots are brown but firm, some are brown and not firm. There are lots of new roots and one new lead (it is a tiny, white thing). However, many of the root tips on the healthy roots have turned brownish or black since yesterday. Or at least, I didn't notice it yesterday. In the meantime, does anyone have general bulbo tips? Watering, light, temperature, fertilizing, etc? Thanks.



Here's the lead:

This leaf looks greener than actually is... I had the flash on.
