Congrats on your new vanda! I have had mine for over a year now, and it is probably still 3 or 4 years from blooming, sigh... Anyhow, im not sure about the indentations on the leaves of your plant, but peroxide was a good decision. Since you are doing vase culture (I was doing this for my coerulea for a while), I would recommend soaking the entire plant in peroxide to eliminate any mold or fungus spores. I used to do that every few weeks with my little vanda seedlings because the humid vase is perfect for growing all sorts of things.

Anyway, this is an absolutely lovely species, in all its forms, I can't wait to see your blooms when they come!
