Millet, no. The plastic meets the ground. When it's warm outside I place blocks of wood or pots or whatever under the edges of plastic on the walls and open door to help vent tree. I've heard of some folks leaving an open gap at bottom of their enclosures and then packing straw or mulch at base to insulate more "on cold nights"; however, it gets extremely cold here and stays cold here for days, nights, weeks. A few years ago it hardly got above freezing for entire month of January. I have too many citrus outside to run around every other day moving piles of straw/mulch. I can open a door in morning before driving to work, and roll it down and tape it shut with strips of duct tape at night. Often it's already below freezing here before I get home from work around 5:30 PM in winter.

Already 33 degrees F here with high winds, predicted to be 50-60 mph tonight. High of 54 degrees F. My stuff is covered. Supposed to get to 29 degrees in Asheville, and since it's snowing, I'll probably end up 5-10 degrees colder than there.

Millet, Colorado usually gets cold and snow in October doesn't it? Being originally from FL, that amazes me. I'm sure your greenhouse can hold up a lot of snow! Can you post a pic of your greenhouse? I've imagined it being huge like one at an arboretum since you have in ground trees.  They have a huge in ground grapefruit in a big greenhouse at Daniel Stowe Botanical Garden in Belmont, NC.

Last night was the first freezeof the season at my house and the low was 29 degrees F, and was freezing or below for 13.5 hours. Trees under cover were fine of course and the new growth on my citranges which were not protected appears unscathed.
