no need for a greenhouse in the bay area, I don't see how your gonna get 4 harvest a year without light dep and supplemental lighting. just grow outdoors or start indoors in march or april in a sunny window and t5 lighting to extend the days a few hours. where the greenhouse helps is nov to mar when you're growing a summer crop in winter, the other 7 months of the year a greenhouse gets to hot and needs a ridge vent and roll up sides
