Grand Cayman Orchidarium questions

[boytjie]

Hello all! I posted a similar thread in the wrong forum and didn't get any response, so figured I'd re-post under Terrarium Gardening.

I recently acquired a very lightly-used Grand Cayman Orchidarium for a ridiculously low price that I couldn't pass up. Now I understand that "orchidarium" might be a dodgy word on the board these days, but this is the "real" thing, so I assume it's okay to talk about it.

I'll be setting this thing up over the weekend and hope to shift my whole collection of 'chids (about 75 plants) off my baker's racks and into it. I've got Catts and Laelias, lots of Bulbos, some latouria Dendrobiums, Dendrochilums, Tolumnias, a few supposedly warmth-tolerant Masdies, some Angraecoids, and about a dozen species Phals and Paphs. Lots of these are mounties. Couple of quick questions, for those who may have this or similar models: do you leave the fans on 24/7 to dry out plants after watering, or do you rather try to strike a balance between higher humidity and better circulation? Do you find you water less? My primary reason for switching is so that I can go away on weekends and not make friends and family responsible for daily care. Also, any maintenance tips/tricks would be greatly appreciated.

Thanks!
