Phals, for example, generally need to have a marked drop in temperature of about
10°F between day and night in order to bloom.
Others like Cymbidiums do also, but I, not being a Cym grower, am not sure in
this case if it is an absolute temperature (like at least down to 40°F) or also
a temperature drop that they need.
Even others, such as Cypripediums, which grow in temperate climates need a frost
in order to bloom.

I am new to growing orchids and to newsgroups as well. I have read in a
recent post here of something called "cold treatments". Could anyone tell me
what these are, and do they help orchids to produce blooms?
