I've only been growing orchids, and in a tent, for about 2 months. Depending on positioning in the tent, the plants get a 10-15f day/night swing in temp (my thermostat is set for 68f in the evening). This can be manipulated to some extent with fans and vent configurations.
The following, which did not have spikes/sheaths when I purchased them, began developing them after some root and vegetative growth: C. aurantiaca, C. Zheng Yi Cranberry, Epc Magic Wand, Onc. Twinkle Pink Profusion, and Dinema polybulbon.
Post pics when you get it set up.
