Glass building to shelter and heat plants

A greenhouse is a glass-walled building intended to shelter and provide a warm environment for plants. They are typically used in cooler climates. The glass allows the building to absorb the maximum amount of sunlight available, but restrict heat loss (roof sections typically allow ventilation and some heat control). Some greenhouses also have their own heating.

Use this tag for questions about greenhouses themselves, and growing in a greenhouse environment.

Waking at 1 am, I get my shoes on to run out to my greenhouse. I've had a heck of a time getting my garden in this year. I've lost quite a few plants to 'pop' freezes and I'm probably getting paranoid. The weather report said the low would be 40…
