i just recorded today the tem. @ 44F, thats sorta cold for long beach
Dustin made a really important point. Warm and sunny. Our bicalcaratas, sumatranas, raffs, amps, hookeriana, Vikings all take nights down into the low fifties F (like last week), the days are bright, up to 92 F and humidity at 80 percent +. Eyeglasses fog over when you step through the door. So far, have not used a heater at night this season.
Rod Kruger has noted the same thing. He lives in the hills above Cairns, so whilst it's the tropics, it is cooler than sea-level Cairns. Whist nights can get very cold in mid-winter, days are always warm, and certainly greenhouse temps during the day in the middle of winter are always above 25C. He believes that true lowlanders such as bicalcarata can tolerate cold nights provided the days are very warm.

I've tried growing a few lowlanders like bicalcarata during winter with no success. Temps got into the low 40's regularly with lower winter humidity. The days had sun but temps remained in the upper 60's. So bicalcarata couldn't handle it. My intermediates can but they do stress. And when the warmer day temps return in spring, they put out new growth. Right now the nights are chilly but day temps have been in the low 70's so my intermediates aren't stressing. But some species like albomarginata, longifolia, hirsuta to name a few should stress in another few weeks or so when the temps go lower and the day time temps stay in the 60's. Also the time of sunlight is reduced as well. It gets sunny by maybe 7 am but it doesn't heat up until noonish. It starts cooling down by 3 pm and then it's dark by 5 pm. So shortened days may play a role too.
