This is one of the true Laelias (from Mexico), so it is not a (formerly) rupicoluos Laelia.
Ordinarily, seedlings from flask should be given lower light, higher temperature & higher humidity, than you would for an adult plant of the same species. You can download my suggested care here: Fair Orchids
However, this species is known for being drought resistant. Thus, these seedlings might need a little less than the constant high humidity I normally recommend.
