9.1 Types of Greenhouses

Free-standing greenhouses come in a variety of shapes and sizes (Figure 24). Choice of greenhouse depends on snow load and wind speed of a particular location. Free-standing greenhouses are less expensive than larger structures and are easier to optimize environmental parameters for different crop species. If multiple stand-alone structures are used, increased sanitation protocols are required to prevent insect pest and disease issues from being transferred between structures by workers.

Gutter-connected greenhouses provide a more efficient use of space and reduced overall heating costs during winter compared to stand- alone structures (Figure 25). The upfront cost of this greenhouse style is high and may be cost prohibitive for growers on a limited budget.

Lean-to greenhouses have one wall that borders a building. Light reduction is not severe if the dark wall is the north wall. These types of structures may be useful for decoupled aquaponic systems, as environmental parameters can be controlled independently in each structure.
