Why grocery retailers are embracing rooftop gardens

Stores redefine hyperlocal by growing produce on the premises

The food industry as a whole is in the midst of a shift from unhealthy processed foods to organic, local and all natural foods. Buying local is one of the biggest trends, as more consumers want to ensure that the produce they  are purchasing and feeding to their families is grown nearby.

This consumer behavior has led to an influx of urban greenhouses, rooftop gardens and hydroponic operations. Businesses and retailers are getting the message loud and clear: people prefer to buy foods from their own communities — even if it means spending a little more.

Daniel Levine, director of consumer trends consultancy Avant-Guide Institute, noted the trend is so pervasive that edible gardens are sprouting up at baseball fields like AT&T Park in San Francisco. Beehives are also being placed on roofs of hotels and other buildings in cities around the world, and urban rooftop algae farms in Bangkok are experimenting with growing edible items like spirulina seaweed.

“The trend for all things ‘hyper local’ is heating up. Consumers perceive that food grown locally is fresher, healthier and better for the environment,” Levine told Food Dive in an email. “People view it as healthier because they can actually see where it was grown. Fresher because, well, it can literally be consumed the day it was picked. And better for the environment because it doesn’t require excessive transportation or packaging to get from farm to table.”

Store to table?

Ken VandeVrede, chief operating officer of Edible Garden, a family of co-op local growers across the United States whose farmers specialize in fresh, hydroponic produce and offer consumers safe, nutrient-rich herbs and leafy greens directly in the supermarket, noted local is getting closer and closer to home.

“Edible Garden grows fresh and local produce for supermarkets, and we find that a major component to our success is the fact that our produce is grown just a short distance from the stores that we ship to,” VandeVrede told Food Dive. “Local produce has nothing but benefits for consumers. Produce grown locally guarantees that the product is fresh, it wasn’t grown in a different country, and that it hasn’t been sitting on a truck for a week. Would you rather buy produce shipped in from Mexico, or produce that was grown at or near the location you are buying it?”

Some innovative grocery retailers are taking things one step further and are growing produce in their own stores— or in the case of Whole Foods Market and its Gowanus Brooklyn store, growing it on the roof.

Designed and operated by Gotham Greens in 2013, the store’s rooftop greenhouse features more than 20,000 square feet of space and grows approximately 250,000 pounds of fresh leafy greens, herbs and tomatoes each year.

A spokesperson for Gotham Greens said the partnership with Whole Foods Market was a perfect match for the company based on the retailer’s unparalleled leadership and commitment to promoting local, healthy and sustainably produced food.

Levine said rooftop gardens are shining in their moment in the sun, and that retailers need to be on-trend to attract customers and keep a step ahead of their competition.

“Today’s grocers, once again led by Whole Foods, are enthusiastically embracing the hyper-local trend as a point of differentiation,” he said. “At the same time, the best ones are solidifying their position as integral members of their communities by inviting customers to learn about the how’s and why’s of urban farming.”

Considering the long journey that most fresh produce has to get to the store and the high level of spoilage, shrinkage and waste in retail produce departments, growing at least some of the food right on the sales floor might be a better option for both the store and its customers.

Recently, Target announced it was researching the idea of vertical farming for some of its stores as part of its current food innovation efforts. Business Insider reported that Target hopes to grow plants and vegetables indoors in climatized conditions and sell the food from the in-store gardens to customers as early as next spring.

“We need to be able to see more effectively around corners in terms of where is the overall food and agriculture industries going domestically and globally,” Casey Carl, Target’s chief strategy and innovation officer, told Business Insider.

What transportation costs?

By utilizing this sustainable and environmentally friendly technology, things like transportation, storage and refrigeration are no longer challenges in getting fresh produce quickly to consumers.

Whole Foods was not the first grocery store to experiment with growing produce in-store. Rouses Supermarkets’ Thibodaux, LA store began a Roots on the Rooftop program in May 2012. It offered fresh-grown herbs to its customers and foodservice production areas — and also grew profits.

Rouses also appears to be the first U.S. grocer to have developed its own aeroponic urban farm on its rooftop. The vertical aeroponic tower garden utilizes water rather than soil, and allows the crops to grow up instead of out. It was developed by a former Disney greenhouse manager, and the same system is used at Disney World, Chicago O’Hare Airport and on the Manhattan rooftop of Bell Book & Candle restaurant.

The store originally employed a local agriculture consultant to get everything set up properly. Now the store’s staff — headed up by an experienced horticulture professional and a team of associates — handle the rooftop garden. According to a company spokesperson, the Rouses team plans the farm management process from germination of the upcoming crop, planting, daily monitoring and logging of the crops progress through to the harvest cycle.

Rouses currently has alliances with a handful of other nearby hydroponic farmers who grow lettuce and herbs, saving on transportation costs.

Earlier this year the Metro Supermarket in Berlin, Germany introduced The Infarm, a miniature greenhouse in its store that grows herbs and greens like wasabi mustard greens and mizuna. A story in Fast Co.Exist reported that the thought behind the idea was to make vertical farming and fresh produce accessible to the public by allowing shoppers to grab vegetables straight from the source. The vegetables live their entire growth cycle within the greenhouse, from seed to harvest

It’s expected that the program will expand and can be adjusted at each store to grow a variety of items, including chilis, eggplants and tomatoes.

Mary Holmes, who teaches a course called “The Future of Food” at Case Western Reserve University, located in Cleveland, Ohio, said one challenge is that many of the greenhouses and rooftop gardens won’t have enough supply to keep the large grocery stores stocked with food. However, she does feel more retailers will begin offering these products in the years ahead.
