Happy Valley Organics. The name conjures great imagery in both lifestyle and nutrition. One could picture rows and rows of multicolored field vegetables, tractors tilling long straight rows of bright green kale or seasonal farm workers adding their rich cultural handprint to our food cycle. Truthfully, that would be a fairly accurate image. But what about photosynthetically active radiation (PAR), watts per meter squared (W/m2) or Daily Light Integral (DLI) lighting? For Happy Valley Organics that is the language of their extensive greenhouse operation.
