Which orchids DO NOT need a temp drop to bloom?

[Steve83]

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.

When I had mine in a tent, I induced blooms in my phals by keeping them on a 24/7 heating mat for several weeks, then putting the heating mat on the lighting timer. As far as they were concerned, they had a short summer in the 90s and then it started getting "cold" at night, with up to a 20 degree drop down to 74ish. That was the ONLY time I got my Phals into a big ol fancy display.

Then I moved, and everything has been limping along.
