Orchids starting new growths heading into winter

[Jinh]

Just wondering what everyone does when heading into winter, but their orchids are starting new growths?

Temps are getting into 40s/50s (night) here, so I’ve cut back watering and fertilizing. However, I do have a few orchids that are just starting to produce new growths.

Off the top of my head, my Encyclia Rioclarense, Dendrobium Spectabile, Prothechea Cochleata, Stanhopea Connata, and a NOID oncidium are all doing this. I have a grow tent and lights that I could put them in to create conditions more hospitable for growth. Should I keep them warm and continue fertilizing or just leave them be and give winter care?

When that happens here, I keep fertilizing.
About temps, as long as they don't dip too much, I wouldn't do nothing different and let them be.

Remember, all orchids don't come from (or have ancestors that come from) areas where winter is cool/dry. That's typical at higher latitudes. Some from semi-tropical latitudes at low elevations may get less rain but not necessarily cold. Those from lower elevations at near-equatorial latitude don't experience "winter" or in many cases, much seasonal difference at all. So if they are growing, treat accordingly, water and fertilizer are completely appropriate. Different orchids have different growth patterns and different needs.
