We're just about at our one-year mark of the solar greenhouse in our backyard. I've not updated about this project for a while. Part of the reason is
that I've been just so darned busy (some of which I will explain here very, very soon)...
Another reason I've not posted much about it is that after we had
so much loss from late blight (and so EARLY it was!), the gloss was off the
apple, so to speak. It was not the most joyous summer gardening season.
However -- there is still plenty going on and we plan on going through the
entire fall and winter with crops in the ground providing us with food!
Which re-invigorates and energizes me.
We have 4 beds outdoors under floating row cover. More like BLOWING row
cover. It's hard to keep that stuff pinned down yet able to be
opened for harvesting. But things are going just beautifully under the
cover, which is rated to give about 6 degrees F and -- quite
importantly -- some wind protection.
We have many different things growing splendidly outdoors under cover.
From memory (and I'll miss a few) they include: arugula, 2 types of bok
choy, tatsoi, 2 types of turnips, broccoli raab, red mustard, 4 types
of kale (Chinese, curly Siberian, red Russian, Tuscan), chard,
napa-type cabbage, green and savoy heading cabbages, collards, mibuna,
mixed chicories, beets, red choy sum, parsley, chives. We are eating daily from these beds.

We closed up the greenhouse in mid-October when we had the first
frosts. Inside, we had a touch of frost for the first time a few night
ago -- I think that night it was 25F or so. But only the nasturtiums
got nipped (an outer row), and it wasn't a fully killing frost for
them. I have a variety of pepper plants (!) doing fine, and a few
summer herbs and flowers, too. Eggplants, cucumbers and basil
couldn't deal with the lower temps and got moldy and sad; I took them
out a couple of weeks ago. We seem to be running a month behind the first frost of mid-October.
I only just added row cover inside the greenhouse in a couple of areas last night, and
then only where we still have the tender summer plants. Also inside I have in
addition to ALL the types I have outside, some leaf and semi-heading
lettuces (could probably have them outside, too), miner's lettuce,
sage, carrots, beets, leeks, scallions, 2 types of peas, red cabbage, red chard, and an additional type of chard whose
frost tolerance is unknown to me. We have regularly been eating from these beds, too.
I have every spot in the greenhouse beds
planted; I will seed some things today that I had meant to seed a couple
of weeks ago; they will go into the spots the summer plants will vacate
-- though I have no idea how much longer these warm-ones will be doing
well enough to keep in place.
At the moment, despite the cloudy day we're having today, the greenhouse is
20 degrees warmer than outdoors -- and there's no wind. The heat in the
earth after a few nice days plus the warmth of the (low) sunlight all allow it to be in the mid-60's indoors. And it's humid and fragrant from earth and
growing things! Quite delightful.

We had a class here on Saturday from the Audubon Society and Concord-Carlisle Adult Ed on Suburban Backyard Farming, and it was over 80 degrees (even with some
ventilation open) in the greenhouse! It was a great demonstration of what
just a little plastic protection and temperature buffering from the
earth will do for you.
