Environmental Control with Greenhouses Greenhouses allow a gardener the unique opportunity to control the climate no matter what’s actually happening outside. In some regions, having better control means you can grow a wider range of plants, even if they never get to venture outdoors. Many gardeners keep the chill off their plants with unheated greenhouses or cold frames, but this is the least flexible of greenhouse structures. Year-round greenhouse growers will need more complicated systems fitted with heating and cooling systems, ventilation, lights, and shades to cloak plants that require darkness to flower. These types of greenhouses host the widest range of plants, and can often be adjusted to support nearly any type of plant life. Larger greenhouses can be divided internally to create climate zones, allowing different growing conditions within the same structure.
