What to do about morning dew?

[katsucats]

I was under the impression that if I kept my orchids dry, it would be okay. I put my orchids out, and immediately I realized that was going to be impossible due to dew, that even if I put them under shade cloth or a tarp, if the temperature drops below the dew point, the leaves are going to get wet. Maybe that doesn't matter much when the temperature is around 45-50 at night right now, but is this going to be a problem when the temperature drops to 37-40?
