The Oku Family takes great pride in providing the best lettuce possible. Created in insect protected, screened greenhouses, the lettuce is grown atop floating rafts in very large ponds, only taking up the nutrients that the plant needs, with no ground water pollution. This method uses only 5% of the water of traditional farming, and nothing more. They believe Hydroponics is the future of Sustainable Agriculture. The Oku Nursery is located in a beautiful valley in the small town of Pescadero CA, proudly standing 5 generations.
