New to cymbidium

[Rothrock42]

A couple of months ago, I got Cymbidium tracyanum, my first cymbidium. I've had other orchids for a couple of years and done fairly well with them, but I don't quite have the rapport with them that I've found with the other genera. Some advice please....

The plant is fairly established (I think), gallon pot, two large leafless backbulbs and three with leaves. I've noticed two new growths on either side of one of the leafy bulbs. At first I thought it might be bloom spikes, but now I think they look more like new bulbs. Do cymbidiums have basal or interaxial bloom spikes?

If they are new bulbs, should it be growing new bulbs now? I live in Portland, Oregon and the night time temperatures are getting down to low 40s. I'm on the 20th floor of a high-rise and keep it on my balcony with a western exposure where it has some protection from the elements -- glass under the railing to protect from wind, reflected and residual heat from the large windows, cement as a heat sink, and the balcony above to prevent too much moisture as the temps sink.

Soon though, the nigh time temps will go into the low 30s and I think I will need to bring it in. Since I'm in an apartment there really isn't anywhere I can put it that is cool. Does it really need a months long cold snap or should several weeks of 40s and 30s do it?
