Den-phal keikis in s/h?
 

I have a Den. "Little Princess" that died due to neglect but it grew a bunch of keikis that I'd like to rescue and plant in s/h. All they have are air roots right now and I'm not sure if they would be appropriate to convert to s/h or should I plant them normally and wait until there is new root growth? Or is there a better option?

If the roots are growing, and you can keep the container and plant warm for the next couple of months, you can move them to S/H, and they should do well.

Not all of them, but some of them are growing. I'm in South Florida so I should have outside warmth for the next couple months and then I can move it indoors.

What range of temps am I looking for to ensure (or help) root growth?

For most hybrids, the warmer the better, up to maybe 95 degrees F / 35C. Your outdoor temperatures should be fine. People grow Phals in houses kept 68 - 72 F / 20-22C but I can't imagine living in an icebox like that.

Oh yeah, I won't have any problems then.

I'm from MI and during winter 68-72 was pretty warm to keep the heat on in the house. I've lived in SW FL for 9 years and I cry when the outside temp gets below 70. :rofl:
