    I believe some orchids can take up to 90-100 f degrees as long as there is enough humidity and air circulation =) but i'm not sure if this is correct.

    I'd be worried about the phal. Now if they are Laelia anceps or renantheras, then I wouldn't be worried.

    you should also put all of your orchids on top of humidity trays so you can raise the humidity and wetting the floor around your orchids also help.

    Mine live outside in a lathe house and have high heat and humidity about 9 months out of the year. Just have to keep an eye out for fungus.
