CHRIS AHRENS'
GREENHOUSE
by Chris
Ahrens
(Illustrated by George R.
Clark, VITA Volunteer)
SPECIFICATIONS--NOTES
This
prefabricated greenhouse can be added to the south side of
cas10.gif (600x600)
an existing
house for under $225.
Sides and top
roof sections are prefabricated sandwich sections
6"
thick, well insulated using an exterior plywood or
"Homosote"
paperboard facing.
The 4' X 8'
clear panels are covered on both sides with #6S
greenhouse
polyethylene on a 1" X 2" frame. A light, drop blind
of framed
styrofoam panels can be added to cover the clear
panels when
the sun is not shining for additional insulation.
All joints
between panels should be caulked or sealed with tape
to provide as
waterproof a joint as possible.
Reflective
side of the fiberglass insulation should be to the
interior to
provide additional light to the plants. Storage
cans of water
or rock/bricks painted dull black will provide
additional
heat storage for sunless periods.

VITA TECHNICAL
BULLETINS
This Technical Bulletin is
one of a series of
publications that offer
do-it-yourself technology
information on a wide variety
of subjects.
Technical Bulletins are idea
generators, intended
not so much to provide a
definitive answer as to
guide the user's thinking and
planning. Premises
are sound and testing results
are provided, if
available.
Users of the information are asked to send us their
evaluations and comments
based on their experiences.
Results are incorporated into
subsequent
editions, thus providing
additional guidelines for
adaptation and use in a
greater variety of conditions.
