Two Small Greenhouses
This greenhouse was built almost entirely out of recycled building materials, including old doors and windows from home-renovation projects.
There is also a garage-sale sink. The homeowner grows a variety of plants in her greenhouse, including parsley, chives, chard, arugula, oregano, cantaloupe, green beans, zucchini and heirloom tomatoes.
Interplanting is the process of scattering and mixing plants rather than grouping crops together in rows. This seems to confuse bugs by keeping the scents diluted. A "bird patrol," or birdhouses placed all around the yard, invite birds, which feed on the bugs.
The second greenhouse is a hoophouse, an arched metal frame wrapped in clear plastic. The tentlike structure is an inexpensive alternative to traditional glass-paned greenhouses.
The interior temperature is maintained in a number of ways, including a propane heater, a ventilation fan and heating mats for seedlings.
The plastic skin of the greenhouse itself can be covered with an adjustable shade cloth as needed.
