1st time Den mount Q's

[isurus79]

I always mount with a wad of spag, no matter what species. I have very dry conditions though, even though I water every day for most of the year. It really depends on what kind of conditions you can provide. As for the white stuff, I can't tell what it is is from the picture. Dry orchid roots tend to be white and some are even fuzzy. Once you mount it, it should dry quickly enough to kill any fungus, if that is what it is. Can you get a pic of the fuzzy roots that are more clear?
