Not really being familiar with other types of orchids I would say you could try Dracula’s, Miltoniopsis, Odontoglossums, Restrepia and Pleurothallis, I also believe there are also some Paphiopedilums and cymbidiums that also like cooler growing conditions. Always ask the seller for growing conditions if its not stated in the advert, I’m sure you’ll find a good growing companion for your massies.
