Cattleya mini purple no roots on new growth convert to s/h?

[Andrew123]

from Massachusetts. After lurking on orchidboard for many months and sucking in information from all of your minds Anyhow, I just got a seedling cattleya mini purple coeruela and it had a pretty mature new growth but didn't have a single new root. Originally, I was planning to convert to s/h but I'm not sure what to do now. Online, I found an article that says that the walkeriana (which is a parent) doesn't produce roots on the growths from the winter. I was wondering if any of you could confirm this fact? Sorry for such a lengthy post
