Yeah, that gives me a day's grace, for sure. But my Vandas are out there in the hoop house now, because it's the sunniest, warmest spot in the garden all winter. They start dropping leaves if I let them get below about 50deg. I also have tomatoes on the vine and some great looking pepper plants in bloom that need to keep warm. So, tomorrow evening, the cover goes on again. C'est la vie.
It's not onerous, except that I'm a bit shaky from my illness at the moment, and requires climbing on my little 3-step ladder.
