1 MITCHELL C.E.A. GroRak Controlled Environment Agriculture Design, Consulting and Development GroRak AdvantagesThe GroRak tm Micro Climate System has these advantages over greenhouse grownhydroponic produce production: 60% Less Water Use 50% Less Nutrients Use 50% Less Labor Use 80% Less Heat Use 20% Fewer Days to Harvest 400 to 600% Increase in Utilization of CEA Space 550 to 650% Increase in production per year per sq. ft. No pesticides, fungicides or chemicals of any kind are used.
2 GroRak TM HIGH YIELD SELF CONTAINED Controlled Environment AgricultureGroRak systems are an environmentally sound, self contained and highly profitable innovation infresh locally-grown produce. These low cost, high yield systems are the new paradigm in superiorquality produce for restaurants, institutions and retail produce outlets serving health consciousconsumers and community health service organizations.People throughout the world deserve the opportunity to eat fresh, wholesome, locally-grown food.Continued growth of populations increases demand for high quality produce and increases de-mand for land and water for uses other than agriculture. The public demand for healthy, safe, con-tamination-free, top quality food has long passed the “fad” stage and has become the growingstandard now driving the whole foods and organic foods explosion across the US and Europe.Conventional agriculture faces continual increases in input costs from land, supplies, labor, fuel,transportation and availability of quality water. These factors have led to the decline of U.S. agricul-ture and to the importation of more than 60% of fresh produce. Although Controlled EnvironmentAgriculture (CEA) is not immune from production cost increases, the net effect can be much lessdue to efficient use of inputs, excellent pack-out rates, and high crop yields.Well managed CEA facilities can grow vast quantities of superior quality produce at a fraction ofthe cost of conventional agricultural systems.Market ResearchThe U.S. consumption of lettuce has grown 53% from 22.4 pounds per capita in 1970 to 34.4pounds per capita in 2005. Per capita consumption of Romaine and leaf lettuce has grown from 0pounds per capita in 1984 to 12.3 pounds per capita in 2005.Romaine accounts for 8.3 pounds per capita and leaf lettuce accounts for 4 pounds per capita. Theconsumption of head lettuce has decreased from a maximum of 29.7 pounds per capita in 1989 to20.1 pounds per capita in 2005. There are about 7 million people living in the San Francisco BayArea. A minimum of 30 million pounds of green leaf lettuce are consumed per year in the S.F. BayArea Counties. California consumes approximately 150 million pounds of green leaf lettuce peryear.
3Market opportunitiesFood SafetyRecent food-borne illness outbreaks associated with fresh spinach and lettuce has led to increasedgovernmental scrutiny of growing and handling methods of leafy greens. Produce buyers are in-creasing requirements for food safety standards. This heighten awareness of produce food safetygives Green Streets (GS) the opportunity to gain customers by promoting the GS strict food safetyprotocol. GS products and facilities will be HACCPcompliant and Third Party certified.Climate ChangeGrowing food crops in a protected and controlled environment the impact of climate change onfood production systems. Food grown outside is affected by too much or little precipitation, heat orcold, wind, storms, etc. CEA food production protects the growing crops from extremes in weatherand guarantees a high quality product throughout the year. The GS sustainable CEA system con-serves water, energy and labor while also capturing precipitation and generating energy from re-newable resource. The GS CEA system uses 1 gallon of water to grow each head of lettuce com-pared to 160 gallons used per head of field grown. As weather systems become more extremedue to climate change and field-grown lettuce availability becomes more variable, food produced inthe GS CEA system will become more valuable to produce buyers throughout the U.S. and theworld.Local and SustainableGrowing food sustainably and distributing them locally has become a very popular movement allover the world. As people become more concerned about their health and saving the environment,they want to eat food that was grown locally on a sustainable farm and not sprayed with harmfulchemicals. The benefits of food handled this way are getting constant media attention. Restau-rants and stores are labeling food “Local” or “Sustainably Grown”.
4 MITCHELL C.E.A. Controlled Environment Agriculture Design, Consulting and DevelopmentMicroGreen GroRack SystemThe MicroGreen GroRack System is approximately 10 ft. x 4 ft. x 7 ½ ft. high. The frame is con-structed of aluminum angle, which is bolted together with stainless steel hardware and includes eightNSF approved wheels. There are 14 – 20” x 116” growing channels, two on each level that createseven growing levels. These channels are made from F.D.A. compliant plastic. Each level is lit withwater resistant LED grow lights. The Irrigation system includes: 3’ x 3’ reservoir with lid; NSF tubing;fittings; fogging system; NSF ½ HP pump and timer. Also includes harvesting tools and equipment.The GroRaks comes pre-assembled and shipped to locations in shipping containers, eight GroRaksper 40’x 8’ container.Cost: $8,600.00 per GroRakLettuce GroRack SystemThe Lettuce GroRack is the same description as above except there are five levels and eight cov-ered channels 10’ long by 5” wide with 112 plant positions on each level, 560 plant positions total.This GroRack comes with 3 times as many LED lights as the MicroGreen GroRack. LED lights use80% less energy than conventional grow lights. Less than 1 gallon of water is used to grow eachhead of lettuce compared to 160 gallons per head in the field.Cost: $12,800 each per GroRack
5Micro Climate BuildingThis structure is quickly assembled on site to create a freestanding fully controlled microclimate in anexisting building. It is constructed like a greenhouse with steel tubing and plastic on the walls floorand ceiling. These buildings come in all sizes. A 2,000 sq. ft. building will support the growing andharvesting of 15 Racks. Environmental controls are fully automated using chilled water to cool therooms and to circulate and dehumidify the air. Chilled water is 20 times more efficient than air condi-tioning using 50% less energy. The Micro Climate Building creates the perfect climate for lettuceand MicroGreens to grow to their optimum potential.Complete Micro Climate building (warm climates) Cost: $22.50 per sq. ft.

Does not include distribution costs.¹ In 1992, Dr. Paul Talalay and Dr. Jed W. Fahey of the Johns Hopkins University School of Medi-cine isolated a phytochemical in broccoli called sulforaphane glucosinolate. Their studies revealed thatthis compound, when broken down to its active form, sulforaphane, acts as a long-lasting antioxidantthat detoxifies carcinogens in the body. They discovered 1 ounce of broccoli sprouts contained asmuch of the photochemical sulforaphane glucosinolate (SGS) as 1 1/4 pounds of cookedbroccoli. Broccoli sprouts have grown in popularity ever since then.
