Quick Summary

A coolhouse is a type of greenhouse specifically maintained at a cool temperature. This controlled environment is ideal for forcing hardy plants to grow out of season or for storing dormant plants during winter. Greenhouses, in general, are structures designed to protect plants from extreme weather, allowing for controlled cultivation. A cool greenhouse typically maintains a nighttime temperature between 7–10 °C (45–50 °F) and is suitable for plants like azaleas, carnations, daffodils, and tulips.12
