When I called Ken to ask
whether his lemon tree wanted
to star in Mark's film,
I was instantly intrigued by the tree's living accomodations. One of
Ken's garage doors was rotting out and would soon need to be replaced,
so he came up with an outside-the-box solution. He turned the zone into
a sunroom instead.
At first glance, I was
impressed by the kit sunroom Ken had purchased and put
together. I'm not so sure he would have been able to build something as
tight for the same cost from scratch.
From a gardener's
standpoint, the sunroom is also a perfect use of that thermal mass (aka
driveway), with the bonus that plants can be rolled inside if
temperatures drop too low.
This is the sunroom's
first winter, so Ken is watching it carefully to see how it fares in
the cold. So far, he reports that nighttime lows have been about twenty
degrees above exterior temperatures with the garage door open onto a
mostly unheated basement.
