| A greenhouse is basically
an enclosed structure that has transparent or translucent walls
that allow sunlight to warm the space and create a microclimate.
Greenhouses also allow you to control the amount of air and water
your plants receive, as well as the temperature and humidity.
Greenhouses are usually a framework of wood, metal, plastic or
PVC pipes with panes of glass or polycarbonate sheeting on all sides.
Some greenhouses are portable and use polyethylene sheeting. Like
garden
arbors, they are generally easy to assemble and to take apart
for summer storage. Greenhouse kits are available in varying sizes
and styles that can be erected by do-it-yourself homeowners. More
elaborate greenhouses can be built for you by a contractor.
While greenhouses are designed to capture the sun, they are also
designed to control the level of shade with shade cloth or shelving
units. You can have a small area for shade loving plants, and control
the levels of filtered sunlight with different layers of shade cloth.
The variability and flexibility of the greenhouse allows you to
grow just about any kind of plant you want, no matter the climate
of where you live or what time of year you wish to garden!
We'll talk more about how greenhouses work after we discuss the
basic types and their uses and the principles of setting
up your greenhouse.
