Since 1970 we have been testing which varieties of vegetables grow best in our greenhouse climate by planting just about every kind of vegetable and herb available, including varieties from foreign contries and rare Native American seed. This has provided us with an excellent selection from which to choose.

Avoiding a monoculture and planting with species and spatial diversity has resulted in very few pest problems. Also the large diurnal temperature swing provides a built in pest control. After 7 years with no major problems we feel that an organic-biological system can be maintained in the proposed full scale greenhouse.
