I know a lot of orchids like/need a lower night time temp. For anyone who is growing around the house how do you manage temperature changes around the orchids? At night right now I seem to get to 68-69. But when summer hits I will have a hard time reaching that low. My room gets pretty warm during the day and takes awhile to cool. I think last year mid-low 70s is what I averaged at night. I'm shopping around and it seems most everything that I consider need this low temp.
