Cold Frame covered Raised Bed
The burning question was..what angle to build the cold frame. This set us on a journey of discovery... we do not get enough sun in our garden during the winter to have a four season garden so is a late winter/early spring cold frame of any use to us? I think now..yes.
Having found at discount, a piece of Lexan left over from a local greenhouse job, the Capt. built the cold frame. A few weeks back, we set it on the raised bed, sowed seed and waited....
The radishes are growing, and greens have spot germinated...about sixty percent...but not bad.
Here is what Eliot Coleman had to say on the angle of the cold frame for midwinter input:
"Some experimenters have built frames with the lights at a 45° angle facing south to maximize midwinter sun input. Such frames don’t work as well as the traditional low-angle models for two reasons. First, you don’t need maximum heat in midwinter for hardy crops. All they require is the protection of the frame. Second, there seems to be some benefit to having the glass roof near the plants as if it were a covering of snow. The environment inside the traditional low-angle frames better meets the needs of hardy crops."
So again, it's a learning curve. We are thrilled to actually have plants germinating and growing at this time of year.
I do want to leave you with an absolute joy I saw today visiting a garden friend, also with the same first name as myself. This below is the second year for her chard. She says, she harvested last year right up until she couldn't get through the snow any more and it survived the winter. For Nova Scotia..this is pretty darn awesome. Good Health B.
