Masdevallias that would work for me

[The Orchid Boy]

Hi everyone. I don't think I've ever posted or even looked at posts in this section of OB. I spend most of the time in the slipper orchid sections. Slipper orchids are my favorite, masdevallias are my second favorite. Problem is, I'm afraid to try them again I'm not familar with the species or hybrids.

My conditions are T5s or T8s (except during seed starting time, March-April), 63% to 75% RH, 65F to 67F night time temps, 73F to 78F day time temps. I prefer species over hybrids, I'm a "species freak." I have a Masdevallia Aquarius now that is my first and only masdevallia that is recovering and I'm doing an experimental potting method with it. What would you guys reccomend for species? I like the ones that stay small but get full and bushy over the ones that are taller and not as bushy. I'm most concerned about humidity levels dropping to 63%, not cool enough night time temps, and cooking them with the T5s.
