Indoor Farm Provides Fresh Lettuce
To Charleston County Schools

Vertical Roots, a hydroponic farm in Charleston, looks different compared to a traditional farm. Inside the upcycled shipping containers, individual heads of bright green and red lettuce line the walls as they complete the growing process without touching the outdoors.
Vertical Roots’ goal is to revolutionize the way communities grow, distribute and consume food.
“All the founders of the company have always been very inspired and motivated by feeding the community healthy, nutritious food,” said Jessica Diaz, the sales manager at Vertical Roots.

The school system is no exception to the organization’s mission. At the end of February, Vertical Roots began providing all of Charleston County schools with fresh lettuce from the farm.
“They’ve never been in the position where they could have a local lettuce provider,” said Diaz. “You have to be able to provide that product year-round for it to be an option for the farm-to-school program.”
In order to provide food to the schools, a farm has to meet the requirements of the Fresh Fruits and Vegetables Order Receipt System Catalog from the Department of Agriculture, which includes sufficient quantity and ability to produce a consistent supply.
Since Vertical Roots’ lettuce is grown indoors in a controlled environment, the lettuce is not impacted by environmental factors, like flooding, droughts or even seasonal changes. This means the lettuce can be produced year-round with each container growing 3,400 heads of lettuce per harvest.
Vertical Roots’ two farms in Charleston and Columbia produced approximately 3 million pounds of lettuce in 2020.
Diaz said it’s taken several years to scale up to the capacity that the farm is currently at; Vertical Roots began in 2016 and currently, it’s the largest hydroponic container farm in the country. The farm provides lettuce to over 1,200 retail locations across 11 states in the Southeast.

Vertical Roots initially connected with the CCSD in January 2020 during its Harvest of the Month program. Each month, CCSD’s Nutrition Services, in partnership with the Green Heart Project, provides students with nutrition education with a focus on locally grown produce.
“Based on the success of that program, we started having conversations about what would it look like to service the school district in a more meaningful way,” Diaz said.
Each school district is allocated a specific amount of money from the government that goes towards fresh fruits and vegetables based on the number of students and school sizes, according to Kerrie Hollifield, a registered dietitian with the CCSD Office of Nutrition.
She said it’s up to the district on how the funds are spent and CCSD is committed to providing fresh, local produce to students and staff so partnering with Vertical Roots became a natural fit.
The current lettuce options at the schools are the Green Butter lettuce and a cut spring mix. Each day, the schools offer an entrée salad that includes Vertical Roots lettuce, grilled chicken and fresh vegetables including tomatoes, cucumbers, and carrots. There is also a side salad option. Occasionally, the schools will offer other options like a lettuce wrap sandwich.
Hollifield said all of the lettuce in Charleston County schools is from Vertical Roots, which means over 50,000 students from 84 schools have a fresh lettuce option. “It’s been awesome to see the kids get excited about salads,” she said.
Since the initiative began, Emily Trogdon, the public relations specialist for Vertical Roots, said the farm has received positive feedback from teachers and parents who are excited that fresh, local lettuce is now available at the schools.
“Children, in general, are always geared towards sweets and candies, salty snacks, but to see them genuinely enjoying the vegetable is just a testament to the product quality itself and to the amazing work that the nutrition program has been doing in the schools,” said Trogdon.
Typically, lettuce that is consumed on a food service or retail level is grown in California or Arizona, so most lettuce travels 2,000 miles before reaching a restaurant or grocery store.
Vertical Roots’ goal is to close the “farm-to-table gap” by providing lettuce with close to zero food miles.

Charleston County schools have not had a local lettuce option until the partnership with Vertical Roots because lettuce cannot be grown year-round in South Carolina on a traditional, outdoor farm.
In addition to being grown locally, Vertical Roots’ lettuce is not treated with chemicals or pesticides. Trogdon said she likes to tell people the produce is 100 percent lettuce.
“The produce is incredibly clean and safe to consume,” Trogdon said. “That’s a barrier that the school system doesn’t have to jump over with our produce.”
Vertical Roots controls the entire environment as the lettuce matures from propagation to harvest. The temperature, humidity, amount of light, and water are optimized in order to provide the safest and most productive growing environment.
Vertical Roots’ system speeds up the harvest time to 35 days, versus the 45 to 60 days for traditionally grown lettuce.
The organization is committed to sustainability, specifically with water and land conservation. Indoor farming uses up to 95 percent less water compared to traditional farming due to the ability to recycle and re-filter water throughout the system.
The company is also socially sustainable when it comes to providing fair wages for employees.
While part of Vertical Roots’ mission is to revolutionize the produce industry, Diaz said their goal is not to eliminate traditional farming. She said there are many heritage crops in South Carolina that could not be grown in an indoor system, so the organization fully supports the local farming industry.
When it comes to buying locally, Diaz said ultimately it benefits the county and state. “When you’re buying from a local farm, you’re employing local people who spend that money in the local economy,” Diaz said.

USA: Velázquez Bill Would Bring Green Rooftops to Public Schools
Forward-thinking Congresswoman, Nydia Velázquez. @rep_velazquez recently introduced the Public School Green Rooftop Program Act, legislation that will establish a grant program to fund the installation of green roof systems on public school buildings
July 24, 2020
Washington, DC –If Rep. Nydia M. Velázquez (D-NY) has her way, schools may become fertile ground for learning about the environment and sustainability. The New York Representative has authored a bill allocating federal resources for the adoption of green roofs at public elementary and secondary schools, known as the Public School Green Rooftop Program. The bill has the potential to open up a world of environmental and educational benefits for students and the broader community. The legislation would be especially beneficial to urban areas where access to green space is commonly limited.
“There is no better place to begin teaching our children about conservation than our public schools,” said Velázquez. “However, their education does not need to be confined to the classroom. These roofs allow students to directly engage with sustainable practices and see for themselves the impact that environmentally conscious initiatives can have on their hometowns and neighborhoods. By exposing them to these ideas early on in their education, we forge a path to a cleaner, healthier community.”
Under this program, the Department of Energy will implement a grant program for the installation and maintenance of green roof systems. Green roofs are a sustainable, durable method of improving a building’s carbon footprint, as well as a place where exploration by teachers and students of pressing environmental and agricultural issues can take root. Children living in urban areas will have the chance to see these practices firsthand, an opportunity they are not often afforded. The roofs, according to the EPA, provide a notable advantage to urban communities, where greenery is often hard to come by.
This bill follows a legacy of success in other states. According to estimates from the Missouri educational system, green roofs can save a single school up to $41,587 a year in electricity costs alone. These roofs will cut district energy and maintenance costs substantially. A regularly maintained green roof has a longevity of forty years, as opposed to a standard roof’s ten to fifteen. Additionally, the bill grants maintenance funding for up to four years after the installation of every roof.
Teaching outdoors may also confer an additional benefit: open air schoolrooms may mitigate the spread of the novel coronavirus. In the 1900s, schools utilized an open-air classroom to prevent students from contracting tuberculosis. Today, this measure has seen support from elementary school teachers who fear that sending teachers and children back into school buildings may pose a danger.
“While we navigate this year’s public health crisis, we need to ensure that we take careful steps towards reopening, with safety as a priority,” asserted Velázquez. “Green rooftops can answer to the call for safer schooling: additional outdoor space provides an opportunity to increase social distancing and open air. This may be one of the ways we can continue to give children the education they need, safely.”
The bill has received resounding support, with endorsements from notable organizations such as National Resources Defense Council, UPROSE, The Nature Conservancy, New York City Audubon, Green Roofs for Healthy Cities, Green Roof Researcher Alliance, Williamsburg Greenpoint Parents for our Public Schools (WAGPOPS), The HOPE Program, Sustainable South Bronx, The New School Urban Systems Labs, Alive Structures, New York Sun Works, Riverkeeper, Red Hook Rise, Voces Ciudadanas de Sunset Park, Red Hook Rise, New York League of Conservation Voters, Resilient Red Hook, New York Lawyers for the Public Interest, NYC H20, the Gowanus Canal Conservancy, Brooklyn Grange, El Puente, Brooklyn Greenroof, Cypress Hills Local Development Corporation, St. Nicks Alliance, New York Environmental Law & Justice Project, Environmental Justice Initiative, National Lawyers Guild - Environmental Justice Committee and Brooklyn Community Board 6.
“This critical legislation will give other public schools, especially those communities historically overburdened by ecological discrimination, the opportunity to reduce their building's environmental footprint significantly and enhance learning opportunities as our green roof has demonstrated at P.S. 41 in Manhattan,” said Vicki Sando, STEM Teacher and Green Roof Founder of P.S. 41 in New York City.
“We at NYC Audubon and the Green Roof Researchers Alliance are thrilled about this legislation and would like to thank Congresswoman Velázquez for her commitment to the natural world. The Public School Green Rooftop Program will result in the growth of critical habitat for wildlife, make the US more resilient in the face of climate change, and provide our youth the opportunity to experience conservation and environmental science first hand,” said Dustin Partridge of the Green Roof Researchers Alliance and Molly Adams of New York City Audubon.
“Passage of this bill will provide exceptional green roof benefits to children, their parents, and teachers at a time when access to safe, green space is very important to communities, and the need to redress the racial injustices is greater than ever,” said Steven W. Peck, GRP, Founder and President, Green Roofs for Healthy Cities.
“The HOPE Program, with extensive experience building and maintaining green roofs through our social enterprise, fully supports the Public School Green Rooftop program. This initiative will provide cleaner air for children in schools and the surrounding communities; contribute to ambitious local sustainability goals; and has the potential to provide living wage employment opportunities to the communities most impacted by the current crisis. It's a win, win, win,” said Jennifer Mitchell, Executive Director of the HOPE Program.
“Voces Ciudadanas is grateful for Congresswoman Velázquez’s leadership in introducing ‘the Public School Green Rooftop Program’ bill and hopes that Congress passes this bill that prioritizes long-term green investments into our communities that are beneficial on so many fronts including encouraging multidisciplinary learning, facilitating meaningful parent involvement, providing opportunities for physical activity, and promoting healthy eating,” said Victoria Becerra-Quiroz of Voces Ciudadanas de Sunset Park.
The bill, H.R. 7693, has been referred to the House Committee on Education and Labor.
