Temperatures are dropping

[aliceinwl]

Tonight we have a forecasted low in the mid-30s (Fahrenheit) so I brought in all of my warm and intermediate growers for the night.

So far this year:

Phalaenopsis: all but one of my 30 some outdoor Phals have been taking nightime lows in the low 40s fine. One did develop a case of crown rot and is now residing inside full time. I'll probably start carting the rest in nightly now.

Miltonia Sunset: this seems to be my most cold sensitive. It started showing progressive leaf damage when lows started dipping below 50 so I've been bringing it inside over night for the past month. Unfortunately, the cats think it's delicious so I have to make sure it's barricaded.

Miltoniopsis: My 3 have been weathering low 40s with no ill effects, but I brought them in tonight.

Bulldog type Paphs: My 3 have been weathering low 40s with no ill effects, but I brought them in tonight.

Dendrobium phalaenopsis type: Mine has been weathering low 40s fine so far and looks to be starting to spike. I didn't want to tempt fate too much so it came in too.

Dendrobium little atro: I got this one in March it hasn't really taken off for me but looks healthy, it's been weathering low 40s fine, but I'm not sure on its lower limits so I brought it in.

Dendrobium roy tokunaga: I also got this one in March it hasn't really taken off for me but looks healthy, it's been weathering low 40s fine, but I'm not sure on its lower limits so I brought it in.

All of my temperature tolerant Lailea, Cattleya, Stanhopea, Renanthera, and Ansellia are staying outside.

Of my grocery store acquisitions my Dendrobium nobile types are staying outside as are my Oncidiums and other intergenerics, Zygopetalums, Zygonisia, Maxillariella tenuifolia, and Cymbidiums. Unless I see damage, these will stay outside unless frost is predicted. If frost is predicted, all but the Cymbidiums will come in (I do cover the Cymbidiums with a sheet).

All of my outside orchids have been acclimated to these low temperatures. I learned the hard way last winter that fresh winter purchases can't necessarily join their cohorts outside right away.

Is anyone else pushing temperature limits?
