I don't actually completely stop watering in the winter.
Tried that once and lost several stans- bulbs withered and leaves practically JUMPED from the plants.
I do let the media dry down more in winter, and when it feels dry, then I do a single good soak in collected rainwater, then hang it back up near the lights. I keep a very small fan on in my GH so we don't go all rotty.
My stans all then return to the outdoors in late spring.
I just had a late stan open it's blooms;

...and I think it would not have set or bloomed the spike if I had decreased watering so much back in October.
Best wishes and luck to your new stan!!!
