' When the sun shines on a
greenhouse, quantities of_
1, t 'solar energy are trapped,
and most gardeners open the
ventilators or switch on a fan
to g et. rid of the waste heat.
Why waste it? Capture it in a
storage unit and use it to
heat the greenhouse at night,
or to help heat your house,
We have developed an
attractive home greenhouse
over a heat sotrage unit. It
has come through its first
i.
ear successfully. Precise
ergy savings have not
en calculated, and vary in ,,
any case with the weather,
but the greenhouse has
proven to be an absorbing
hobby providing interest,
_enjoyment and a steady
supply of s.aii vegetab.es.
The above -ground portion
is illustrated in the
photograph. The design
includes several essential
features. The door ' opens
onto a closed breezeway to
prevent sudden heat loss - a
small enclosed 'air lock'
porch would serve the same
purpose. The entire struc-
ture is double -glazed glass,
in this case to preserve the
view from the window in the
house behind. All wood
members are cedar, for rot
resistance and good in-il.
ulation value. The walls are
ulated with styrofoam.
e structure is sealed
thoroughly with caulking
compound, and even the
ventilators are sealed
through the winter. A fan
removes the heat to the
storage unit, so the ven-
tilators aree not needed until
late spring.
The unique part of this
structure is a full basement
packed floor -to -ceiling with
water -filled containers
(glass," metal or plastic -
anyth ing-in 'fact that Can be
scrounged from neighbours
and friends). This basement
has a standard concrete floor
- and concrete block walls,
insulated on the outside with
5 -centimetre (2 -:inch)
styrofoam sheets.
Be sure the sheets are well
protected on the outside with
tar to -frustrate the mice,
who will otherwise demolish
the styrofoam in a few years.
The wa,lls and water -filled
containers 'store the heat of
several sunny days ef-
fectively, and release it as
needed.

Wise old,
tasty sage
"Eat sage in May, and
you'll live forever," the En-
glish have been saying ever
since the herb was first intro-
duced by the Romans, who
borrowed it from the Greeks.
Though you may prefer to
grow old more gracefully
than ye olde English, you
can't deny that the use of
sage makes a remarkable dif-
ference in cooking.
With its strong and pun-
gent flavor, it should be used
very sparingly to enhance the
flavor of poultry, veal, stews
,and stuffings.
Sage can be grown easily in
your own backyard, started
from seed, from stem cut-
tings, or by dividing mature
lumps in the spring, accord•

dens."
All you need is well -
drained soil, full sunlight,
and a minimal amount of wa-
ter, since over -watering may
cause mildew. You can pick
sage leaves anytime before,
during or after bloom.
And; don't forget to keep
some around for May just
in case the English are right.

air is blown down from the
greenhouse into the plenum
chamber, through' the holes
in; the pegboard wall across
the entire cross-section of

forced up through vents in
the greenhouse floor,. The

temperature falls to about 10

thermostat as the barn.

air to the adjacent house on
sunny winter days.
To supplement the heating
during long periods of dull
weather, a small thermostat-
controlled fan blows warm
air from the adjacent house
into the greenhouse. Finally,
a smallelectric heater
comes on if. the temperature
approaches 7 C or (45 F) .
Plants in the greenhouse

ttanctentals,
The greenhouse makes an attractive addition to the house. It is also very productive,
supplying fresh salad vegetables all winter long. The solar storage below the green-
house makes it possible to collect sunlight in the daytime for use in the greenhouse at
'night. The extra heat can also be used to supplement heat inside the house proper.
