Except to add windows. In overcast skies and out side temps in the 50's it is heating to 78 degrees and holding to 50 with nighttime temps in the low 40's. There must be enough warming of the raised beds to hold heat.
The thermometer shows the temp after a couple hours of having the roof closed up on the first day. Today it reached 78 degrees with the outside temp at 56.
Thank you all, it was a big job for me, now in my 70's, but the help skinning it was a lifesaver. Very high winds today, it looked ok, but I put ground anchors in all 4 corners to avoid any tendency to "sail".
