Misting or watering at night fall will cause fungal and bacterial disease. Experienced growers do let the plants dry-out before night fall.
Yes, Den. kingianum needs winter rest to bloom well. I am surprised that you haven't heard about it since you live pretty close to its native home. Google around if you don't have a good book or enough growing experience with this species...
Rest period:...In cultivation, water should be greatly reduced from midautaumn until growth resumes in spring. Plants should be allowed to dry out between waterings, but they should not remain dry for prolonged periods. Australian growers recommend just enough water in winter so the pseudobulbous stem do not become shriveled. Fertilizer should be reduced or eliminated when water is reduced. Growers indicate that distinct seasonal variation is essential for plant health.--Orchid Species Culture--Dendrobium by Margaret L. Baker and Charles O. Baker
