Can s/h culture work for outdoor growers?

[NewBloom]

As this thread's title suggests, I grow my orchids outside. I first attempted s/h culture a couple summers ago on a rescue phal. The first few months yielded amazing results in terms of root and leaf growth and then it started going downhill.

I have a den hybrid keiki that I just potted in s/h. It's been sulking in bark and since I've been wanting to give s/h another try, I figured why not. I think the plant will do well during the summer but when it gets cooler November to February, that's another story.

When I've grown my dens in "traditional" orchid media, I've let them remain outside down to 55 degrees. With evaporative cooling in s/h culture I'm guessing that would be too cold

Do you all have any tips on how to successfully grow outside? At around what temperature range should I bring a plant in s/h indoors? Using special equipment like heating mats isn't an option for me outside.

With thanks,
