MICROGREEN BUSINESS GUIDE · DUNDALK, MD

Start a microgreen business in Dundalk, MD.

Most Dundalk residents do not realize that this large Baltimore County community on the Patapsco River anchors a working waterfront market that eats a lot and grows almost none of its own fresh greens. Surrounded by Essex, Rosedale, and Edgemere, with Baltimore minutes up the road, Dundalk's restaurants and grocers source living microgreens from outside the region. A local grower steps into established, sizable demand with little competition.

Quick Answer

You can start a microgreen business in Dundalk with under $400 in initial equipment and grow it into a $1,400 to $4,200 per month side income within 90 days. Here is the local demand picture, the unit economics at Dundalk wholesale prices, and the operating system used by working microgreen farms.

*When a Dundalk or Essex kitchen wants fresh microgreens delivered weekly, where do you think they are sourcing them today. and what would a local grower be worth to that order.*

What Dundalk buys today

Dundalk's waterfront dining and the broader Baltimore restaurant market lean on fresh microgreens for flavor and presentation, especially with the area's strong seafood tradition. A reliable local grower delivering living trays weekly becomes the easy yes for kitchens currently importing them from outside the county.

Baltimore County's farmers markets across the east county and the wider Baltimore metro give a Dundalk grower a direct retail channel with full margins. This large, settled population reliably pays a premium for nutrient-dense greens harvested that morning.

Baltimore-area summers run hot and humid while winters turn cold, making consistent year-round field growing impractical here. Indoor production under lights removes weather entirely, so your trays stay on schedule every week of the year while seasonal field growers shut down.

*If Essex, Rosedale, and Middle River are all a short drive away, how many weekly restaurant stops do you think one Dundalk route could realistically hold.*

Three things every working microgreen farm in Dundalk runs on

  1. A seed density and watering plan you trust. The number one cause of failed trays for new growers is over- or under-seeding. The cheat sheet inside Grown Like A Pro gives you grams per 10x20, soak hours, blackout days, harvest day, and watering for sixty-one varieties.
  2. A rotation tracker. Once you are running thirty-plus trays per week, you cannot remember what is in blackout, what is in light growth, what harvests Tuesday. A spreadsheet works for the first month. After that you need a system that pings you the day before each harvest and reorders seed before you run out.
  3. A customer + invoice layer. Restaurants in Dundalk want predictable weekly invoices and net-15 terms. Farmers market customers want clamshell tracking. Both want consistency. The app handles both.

The IKEA test

If you can follow an IKEA instruction sheet without screaming at the family, you can grow microgreens at a commercial level in Dundalk. The steps are about that difficulty: open the box, lay out the parts, follow the picture, repeat. Trays are the bookcase. Seed is the dowels.

If you ever did struggle with the IKEA bookshelf, that is exactly why Glappy lives inside the app. Glappy is the in-app coach that breaks every step down barney style, in your own language, from "how do I plant my first tray" to "why is this tray going leggy at day five and what do I do about it tonight." Type the question, get a step-by-step answer. There is no question too basic. The whole point is that a Dundalk grower starting today is not on their own.

Dundalk microgreen FAQ

How much can I make growing microgreens in Dundalk?
A working microgreen farm in Dundalk produces $3,000 to $8,000 per month within 90 days of starting. The math: 100 trays per week, $20 to $30 net revenue per tray, harvested in a basement, garage, or spare room. The ceiling is set by how many restaurants and farmers market customers you can serve, not by the growing setup.
Is it legal to sell microgreens in MD?
Yes. In most of Maryland, microgreens fall under the state's cottage food law for direct-to-consumer retail at farmers markets and to private customers. Restaurant wholesale typically requires a basic food handler permit. Verify with the Maryland Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in Dundalk?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Dundalk. Broccoli is the highest-margin variety because of its sulforaphane reputation with health-focused buyers. Specialty varieties like amaranth and shiso command premium pricing from chef-driven restaurants.
How much space do I need to grow microgreens in Dundalk?
A 10 by 10 foot room with two shelving units holds 60 to 80 active trays, which is enough to produce $3,000 to $5,000 per month. A basement, garage corner, spare bedroom, or sunroom all work in Dundalk's climate. Vertical shelving is the fastest path to higher revenue per square foot.

The seed density and watering math is the single biggest predictor of how fast you get there.
Do I need a license to sell microgreens in Dundalk?
For farmers market and direct-to-consumer sales in Dundalk, most growers operate under Maryland's cottage food law with no special license. For wholesale to restaurants and grocery stores, you typically need a basic food handler permit, a sales tax permit, and depending on volume, an inspection from your county health department.
