Ideal daytime temps. for greenhouse?

[Lucinda Brown]

I would like to hear what you experts and enthusiasts think the ideal day temp. for a greenhouse with vandas,cattleyas, denrobiums, a few epidendrum calanthums, and a doritis or 2 and a zygopetalum,phaphiopedilums,phragmipediums would be?My greenhouse is only 10' x 12',I have them grouped already for appropiate light,just can't find all the specs on ideal day temps for all the above to figure a good average.I found paphiopedilum,denrobium,cattleya and vanda day temps,but can't find phragmipedium,zygo's or epidendrums.Can anybody help? It's too small a greenhouse to separate plants into separate areas and cool differently,obviously,so I'm trying do find a 'Happy Medium' day temp for all.PLEASE,PLEASE HELP!

Dear Lucinda,

Based on the plants you listed, I'd recommend a day-time temp not to exceed somewhere around 85F. You have noted that you don't have the set up to accomodate the differences in your plants' requirements so you may find, if you have cool growing Paphs or example, they don't perform up to standard.

Oklahoma is hot, correct? Do you have a cooling mechanism?

Thanks Kmarch,I have an evaporative cooler to cool it.We're going to hook up a thermostat to it soon.Hopefully I can find one that's progamable for 2 temps.-1 for day,1 for night temp.
