Room temperature in winter
Hello again! Another question:
I have a diverse group of orchids, a few cattleyas, a couple dens, 2 cymbidiums, a half-dozen phals, 2 neos, 4 oncidiums, and one miltoniopsis. I'm sort of a windowsill grower. Most are living together in an enclosed stone porch with southeast exposure. Some are in s/h, 2 are mounted. There's a ceiling fan on low that runs pretty much nonstop and I have a humidifier set in the 60% range. The porch is open to the house at all times. I leave the door ajar to hold humidity in.
My question is in regard to the temperature in this room. In the morning, it's currently in the low 60s. As winter sets in, that will go lower into the 50s. During winter days, I utilize a radiant heater that keeps the room in the low 70s. Is this acceptable for this variety of orchids? I don't THINK I have any real heat lovers, do I? I have heat mats under the phals and recent s/h converts. Will continuing to use the mats offset the cold nights? I could use the radiant heater at night at a lower temp, tho it is costly.
