significance of "cool room"

[Ashleyma23]

My oncidioda pagan pacific k tag also states cool room what does this have to do with growth period and blooming period? Thanks

I'm not familiar with this particular hybrid, but it has Cochlioda in it, which are usually cool growers.

I don't know if it requires cool temps for blooming. Maybe some other members can be if more help.

Larger orchid growers have different greenhouses or 'rooms' where the plants grow. That tag indicates it was being raised there, and not in a normal, warmer area.

You will find Masdevallia's marked the same, in some cases.

They need cool temperatures to come into bloom. I have a hybrid similar to this one. I have it on a cool East window sill. I put it outdoors for the summer but if temperatures get too hot, I put them in the basement. I bring it in when frost is a threat.

Orchid growers normally differentiate between cool, intermediate and warm conditions. Cool growing tropical orchids originate from higher altitudes. In the Andes or in Papua New Guinea altitudes of 1800-2800 meters above see level are the area of cool growing genera and species.
Habitats are characterized by condensating clouds (montaneous cloud forest), moving air, more intense ultraviolet radiation, and of course cool temperatures compared to the hot tropical lowland climate.
In higher altitudes the temperature at night drops often to 10°C, and daytime temperatures are about 18-20°C. When the sun breaks through the clouds, the radiation quickly raises the temperature and especially the microclimate around plant leaves to 30°C for 30 or 60 minutes until the next cloud drops temp again. The difference between daytime and nighttime is much more pronounced than in the warm lowland climate.
Plants originating from the lowlands under the tropic of cancer or capricorn (=subtropics) are adapted to a cooler and dryer rest period and a warmer and more humid growth period. Plants from the montaneous cloud forests are habituated to year round more equal growing conditions. Often the flowering season for high altitude growers is not as strict as it is for warm growing plants.

Thank you all for your inputs
And taking the time to answer, so mg question now would be what is the perfect location , I guess not near a window.?

[james mickelso]

but this will grow fine in phal light and temps. and it will bloom just fine in this same environment.

[Ashleyma23]

I steered away from phals because I have killed a million , thanks lol!

I've only really started as an orchid keeper too, and my first oncidium alliance plant was a odontonia (don't know what they call it now) and I put it outside in wind and weather in October/ November bringing it in only at first frost, and it then produced 2 spikes and bloomed in December and the blooms were cut off only in the first week of February. I had not known I could keep them outside the majority of the year at the time in zone 6a. I think for the oncidium types they require exposure to very cool temperatures before they bloom.

[james mickelso]

That may or may not be true. I know they bloom when they have enough energy to bloom. I bloom my odonts/oncids/rossios/brassias when they have grown large enough to bloom. My brassias are throwing spikes now. My oncids just finished for the most part. My temps are quite mild until dec when the nights get downright chilly (30*-40*f) but the days are still mild. In commercial settings the blooming can be pushed by temperature and light level changes so that the growers extend the flowering seasonfor many types of orchids but they will bloom without that manipulation too.
