Hi Mike,

I often leave some Hoyas out in temps into the mid-40's. In fact, just last night it got down into the 40's and I still have several out. I wouldn't worry about temps in the 50's, but just don't keep them too wet. Water them when they get mostly dry, and don't ever let them sit with water in the saucer when it's that cool. I wouldn't feed them at all until spring, too. Letting them go mostly dormant is fine. In fact, letting them do so will often mean extra good flowering next season.

Sounds like you have plenty of bright indirect light, which will help. I'm betting they will be fine.

I think they will be fine, too, especially since it's not a drafty space. But there are some Hoyas that do less well in the cooler temps. If you want to be on the safe side, cross-check your collection against the temperature tolerance list and keep the "warm" species in a different room.

Greedyghost and Denise..Thank you..I knew I could count on you two for the encouragement...

I think they will be ok...Last year when I received them from the nursery and in mail, I had to pot a few and many came already potted, but I don't think they were ready to face the environment I provided in there in which many leaves yellowed and died..
They must of came from warm nurseries and warm areas..

This time they will have adjusted well as the winter approaches and not of a shock..I think they will react nicely now that I can get them use to it...The light naturally gets less and less as compared to getting them from a very sunny area from the south and then sticking them in my room last winter with sudden shock.

I really hope they get use to being in there and as you said, less watering and sort of a rest period might do them well.
It never gets below 55 in there which I think lower than that most plants don't grow or like that at all..

I actually put hooks all along the huge skylight I have so many will hang get light from that....Those will thrive I am pretty sure. I will take a pic and show you what I mean...
I'll try tomorrow..

Again thanks and I will keep you all updated..

Mike

Mike, if they are hanging off the ceiling, the temp there may be a few degrees higher, which is good.
