Climate Control for your Greenhouse

When offering heating and cooling suggestions for optimum climate control for your greenhouse, we ask our customers three things:

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:

  1. In the colder months – heat only what you need. An energy curtain across the bench will keep the lower half toasty warm.
  2. Bubble wrap – Line the interior walls for added insulation.
  3. 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.
