Yep. Plumeria are truly trees, getting anywhere from 20' to 60' tall, depending on variety. There are now dwarfs available, but I suspect even those will get over 6' (just a guess). All my Adeniums are in the solarium and get some hours of sun. Right now they get about 6 hrs. The glass reduces the infra-red by 50% and practically eliminates the UV, so it is more like growing in a shade-house.
