Angraecum Lemforde White Beauty cultural advice needed

[smweaver]

Okay, I couldn't resist purchasing a hybrid earlier today that I found for sale: Angraecum Lemforde White Beauty. I know that it's a primary hybrid of Ang. sesquipedale x magdalenae (or is it the other way around?). But since sesquipedale likes warm temperatures and magdalenae's a highland plant that enjoys a cool and dry winter rest, I'm at a loss for what kind of temperature range this hybrid will appreciate at night. For now I have it spending the night with the Idas, where it's going to get rather cool (last night the minimum temp recorded on the thermometer in that area was just under 54 F). If it would be better to place it in the same area with my sesquipedale (where the minimum night temp doesn't fall below 64 C), by all means will someone please let me know so that I don't turn the poor thing into an ice cube?! Any additional cultural advice/wisdom not relating to temperatures will also, of course, be much appreciated. Also, does anyone know how tall this hybrid needs to get before it will be likely to flower? Thank you!
