FREQUENTLY ASKED QUESTIONS

What kind of company is Brooklyn Grange?
Brooklyn Grange is a commercial urban farm, meaning we grow food and sell it. We want farming to become a thriving and viable industry in cities, and we believe that by practicing urban agriculture as a fiscally sustainable business, we can prove that it is worthy of investment. We also believe that any good business serves its community, which means we are always thinking about how we can have a more positive social and ecological impact on our city!

Where do you sell your produce?
We sell our produce directly to the community at two weekly markets well as to several local restaurants and retail stores.  We have a fifty five-member CSA program through which we distribute shares from Mid-May through October.

How big is the farm?
We farm two rooftops in New York City. Our one-acre (43,000 square foot) Flagship Farm is made up of roughly 1.2 million lbs of soil.  Our Navy Yard farm covers a full 65,000 square foot building.  Our total rooftop farming area is 2.5 acres, or about 108,000 square feet.

Can the building hold that much weight?
Yes, absolutely! Our farms were designed and installed with the support of engineers and architects who assessed and approved the sites. Both roofs are made of thick reinforced concrete slab, approved for loads far in excess of the loads that we have installed.  

How are the farms built?
Both farms consist of green roof systems laid down before the soil. At our Flagship Farm in LIC, we installed a green roof system distributed by Conservation Technology consisting of a layer of root-barrier, which prevents our plants’ roots from penetrating the surface of the roof; a thick layer of geotextile “filter” or “separation” fabric; drainage plates with small cups to hold excess water from heavy rainstorms (the soil and plants wick this stored water up in dry conditions to keep our water use down), and finally, a thin layer of filter fabric to prevent the drainage mats from filling up with the 8-10″ of Rooflite Intensive blend soil.  The soil and materials to build this farm were transported via crane and buggy.

Our second farm at the Brooklyn Navy Yard was installed atop a roof membrane that included a built-in root barrier, so the system we used there is a bit simpler.  It is comprised of a light weight drainage aggregate sandwiched between filter fabric and topped with 10-12″ of Rooflite IntensiveAg blend soil.  The soil for this farm was installed using a blower truck.

What kind of soil do you use?
We source our soil from Skyland in Pennsylvania, a green roof media supplier. The blend is called Rooflite, and is composed of mushroom compost for organic nutrients mixed with lightweight, porous stones. The stones make the material lighter in weight, ensure that it drains well, and also slowly add trace minerals needed by the vegetables. Our beds are about 8-12″ deep with shallow walkways.

What are you growing on the roof?
We grow dozens of crops each season and harvest about 50,000 lbs of produce every year. Our biggest seller and a favorite amongst our farmers and customers alike are our fresh, flavorful leafy greens: from spicy baby mustards to tender young lettuces and peppery arugula, a Brooklyn Grange Greens Mix salad barely needs dressing!

Tomatoes are another of our biggest crops: we have 40 varietals planted. We are also growing peppers, kale, chard, chicories, ground cherries, eggplants, pac choi, herbs, carrots, turnips, radishes, beans, and many other exciting crops!

Is the farm organic?
We grow our vegetables according to organic principles, and we do not use any synthetic or chemical fertilizers, insecticides or herbicides. We are not certified organic by the USDA nor do we plan to apply for organic certification, but we invite the community to visit us and certify our practices with their own five senses.

How do you grow fresh produce in a polluted city?
Pollution is definitely a concern for city farmers, but the pollutants of greatest concern are heavy metals, such as lead, and automotive break pad particulates.  Both are denser than air, so vegetables grown on a rooftop high above the roadways are protected from these contaminants.   The limited lifespan of plants mean they absorb significantly less contamination than our lungs do. We’ve had our air quality tested, and it’s great!

How was the farm financed?

The Flagship Farm was financed through a combination of private equity, loans, grassroots fundraising events, and the crowdfunding platform Kickstarter.com.  The Brooklyn Navy Yard farm was made possible in large part through the support of the Department of Environmental Protection’s Green Infrastructure Stormwater Management grant program, New York City’s innovative and proactive approach to managing combined sewer overflow.

Does the business lease the rooftops it cultivates?

Yes; we have a 15 year lease from RXR Realty and a 20 year lease from the Brooklyn Navy Yard.

Is the farm profitable?

Yes. We broke even in our first year, became profitable in year three, and have shown steady growth every season since we opened. We plan to continue expanding in the coming years, so we can employ more farmers, and have an increasingly important impact on the ecology of New York City. Spring 2016 marked our six year anniversary, and we now have twelve full-time employees as well as over 30 seasonal part-time staff. 

What do you do in the winter?
We farm the roof about nine months of the year. In the winter, we use nitrogen-fixing “cover crops,” like clover and oats, to add nutrients back into our soil and prevent erosion. We also grow amazing microgreens in a greenhouse atop the Navy Yard, and work on other projects, like writing books (The Farm on the Roof, by our co-founder, Anastasia Cole Plakias, was published by Penguin Random House in April 2016). Finally, we're often designing new farms, green roofs, and growing spaces, whether to operate ourselves, or for clients from businesses, residential developments, or institutions. You can check out a portfolio of our design/build work here.

Why Urban Farming?
The city will always rely on rural farmers for the bulk of our food, and the relationship between urban and rural communities must be respected and celebrated. But having farms inside the city limits which take advantage of unused roof space is an opportunity not to be missed. Rooftop farms have the potential to improve urban quality of life, create jobs, increase access to healthy fresh foods, and provide environmental and agricultural education to those of us who live in and love the city.
