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.
Revised August 1981

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.
