Climate Control for your Greenhouse
1) Where will the greenhouse be located?
2) What do you want to grow?
3) How many seasons do you want to use the greenhouse?
The first step is to answer these questions to create an environment that
will work for you. The next step is choosing the best glazing to achieve your
goals most efficiently whether that means a cool, warm or hot greenhouse.
Tips to maintain heat in the greenhouse:
In the colder months – heat only what you need. An energy curtain across
the bench will keep the lower half toasty warm.
Bubble wrap – Line the interior walls for added insulation.
Black barrels – create a thermal heat sync by filling black rain barrels with
water. It will heat up during the day and release the warmth at night.
Circulation is critical in a greenhouse
Circulation helps to maintain even temperatures, controls condensation and
keeps pests at bay. Place your heater on the floor towards back of greenhouse
closest to the door (the source of heat loss). Put a circulating fan on bench
level pointing up and towards the door. This will create a circular motion of
needed air for your plants and increase efficiency in the greenhouse.
Some guidance on required heating & cooling:
This matrix is only a guideline for planning your greenhouse.
Often times there are micro climates within these
zones that require additional planning including lower
zone areas that also get very warm in summer – additional
cooling equipment may be required.
