The
energy efficient greenhouse of tomorrow is just starting to come of
age. Currently only one company (located in California, a very progressive
state) has an active Web presence. However, competition is likely
to increase because greenhouse enthusiasts traditionally have an affinity
for products that promote sustainable living.
There are several features that make the energy efficient greenhouse
use less power. A photovoltaic solar panel draws energy from the sun.
Perimeter insulation prevents the frost from creeping under the walls
of the greenhouse. This helps the soil mass stay at a steady temperature.
Expect to purchase your energy efficient greenhouse over the Internet.
It will cost several thousand dollars. Research the subject first
and if you're serious about the technology consider taking a class
on these greenhouses. These classes are now being offered through
unaccredited institutions that focus on organic farming and sustainable
living.
