Tahoe 10' x 12'
Here is my 10 x 12 twin-wall polycarbonate Charley's greenhouse,
snug and warm in a Feb '05 snowstorm. Its wall-mounted Empire heater is
one of the many things I love about this greenhouse, for it requires no
electricity; thus I never have to worry if the power goes off during
storms like this, and all my plants--including the red cattleya blooming
just inside the door--stay warm and safe through the winter.
