I also use orchidspecies.com as a reference, and the Baker culture sheets (which are contained in Orchidwiz software, which has paid a license fee to the Troy Meyers conservancy for that... especially handy in the listing of minimum and maximum temperatures for habitat) In the absence of that Baker sheet, I look at elevation and latitude - for the equatorial area, I have found that plants that grow between about 1400 and 2000 meters will take night winter temperature close to freezing, and mostly are not too fussy about warm summers with some shading. There are exceptions of course... but this works for me as a rough indication of what I can get away with. For hybrids, you need to look at the percentages... an Slc that is 1/3 Sophronitis coccinea will be fine close to freezing in winter (if dry) but an Slc that is 5% Sophronitis coccinea not so much if the the rest of it consists of warm growing species.
