Their basic function is to protect young plants and seedlings from wind and cold in the early spring, bul they can also be blacked out to induce early flowering and harvest.

Both large and small greenhouses cost more money, time, and space. With the exception of the lightweight "hoop" house or miniature greenhouse, they are also more permanent. The type of greenhouse selected will be determined by the planned use of the space and where it will be located.

Total area of the greenhouse is determined by the number of plants you intend to grow. Allow one square yard (90 cm-') per mature plant. Do not forget to allow about six inches (15 cm) space for air circulation between benches and side-walls. Add space for walkways-standing room only or room for a wheelbarrow-and possibly a center bench. Glass, plastic panels, and sheeting all come in standard widths, and it is easier to build in a size compatible with these units rather than have to cut the panels down. For example, an eight-foot (2.4 m) house can be made with two 48-inch (120 cm) wide fiberglass panels, Center height depends on the level of the eaves. Low growing plants can take an eave of five feet (1.5 m); tall plants need six or seven feet (1.8 or 2.1 m). After determining eave height, a simple formula will give you the center height: Center height = eave + 0.25 width (a twelve-foot wide (3.6 m) house with a five-foot (1.5 m) eave will have a center height of eight feet (2.4 m),

Budget, building skills, and security will weigh heavily in the decision making process. The least expensive structure per square foot (mJ) is an even-span 16-foot (4.8 m) wide that will house two side beds or benches, two walks, and a wide center bed or bench. An 8 to 12 foot (2.4 to 3.6 m) wide lean-to with wide beds or benches and a central walk is the least expensive option overall. Whichever option you choose, building it yourself will be cheaper and more secure than hiring a contractor. You can purchase much of the plumbing and electricity installations in kits or pre-assembled to avoid compromising security.

Climate will play a role in choosing your greenhouse. For example, a cold frame in the mild Pacific Northwest can give you a six-
