Yellow somewhat tender Lyroris

Jim,

  I think I mistook your image test on your part for a spam/email hack.

  A one-word subject and a ling/weird URL are classic hack formats.

Apparently it either never freezes within this frame or many plants which I think of as tender actually take some freezing. During extremely cold periods I've seen frost on the inside of the glass, but I've never seen signs of frost or freezing on the plants themselves (unless the leaves touch the glass).

> I like to tell people that simple cold frames like this one are a lot like dogs: they pretty much take care of themselves, but they definitely need attention at least two times a day. The glass is propped open daily, even in freezing weather (just a tiny bit) and on mild days (much more). NEVER allow sun to strike a closed cold frame. If you have to be away during the day, cover the frame with an opaque tarp or something similar. Even in the dead of winter, sunlight striking the closed frame will quickly send the temperature soaring, enough to kill some plants outright and to damage the foliage of those not killed.

Because the frame is sited against the house, it gets whatever heat seeps from the house foundation. I suspect that this is a significant factor in the success I've had. In really severe weather (those periods when the day time temperature does not get above freezing and the night time temperature hovers down into the single digits F, I'll leave the frames covered with the tarps for days at a time.

The frames are a daily bother, but it's worth it. The only regret I have is that there are only two frames, and they total only eighteen square feet each.  Curiously, I've never had a desire for a greenhouse. But when I'm out working with my frames I'm as happy as can be.
