Louise, most of my plumerias stay outside all year and survive temps in the mid-30's without damage. Damage starts at right around 32 and below. Flowering slows and stops when night time temps enter the 40's or thereabouts, depending upon your microclimates and some other factors. If your nights are 50 or above, I would leave them outside. Plumerias just don't do as well and bloom as well indoors compared to outdoors, but it certainly sounds like your four skylights will be ideal so it is up to you. Plumerias go dormant with reduced daylight (actually increased darkness) and with reduced water and nutrition. With a warm temp like 78 degrees and great lighting with some additional lighting extending the daylight and plenty of water, your plumies can bloom for you all winter. I put all the ones with inflo's in my greenhouse last winter with no additional heat, and they bloomed for me all winter. I watered normally as the plants dried out very quickly due to the intense daytime temps in the greenhouse.
