MICROGREEN BUSINESS GUIDE · NORTH POTOMAC, MD

Start a microgreen business in North Potomac, MD.

Most North Potomac residents do not realize that one of the highest-margin food businesses in Montgomery County can be run from a spare bedroom. This is an affluent corner of the Washington metro, minutes from Gaithersburg and Rockville, where chefs and shoppers already pay premium prices for fresh, local produce. Microgreens fit that market perfectly. They grow in days, not seasons, and they sell for more per ounce than almost anything else on the plate.

Quick Answer

You can start a microgreen business in North Potomac with under $400 in initial equipment and grow it into a $1,500 to $4,000 per month side income within 90 days. Here is the local demand picture, the unit economics at North Potomac wholesale prices, and the operating system used by working microgreen farms.

*When you picture the chefs working the kitchens around Rockville and Gaithersburg, how many of them do you think are settling for wilted greens trucked in from out of state simply because no one local is offering them a better option?*

What North Potomac buys today

The restaurant trade is the obvious first door. North Potomac sits inside one of the wealthiest counties in the country, and the chefs working the Rockville, Gaithersburg, and Potomac corridors compete hard on presentation. A chef who needs pea shoots or micro radish on Thursday cannot wait a week for a distributor. A local grower who can deliver that morning becomes the easy yes.

Then there are the farmers markets and retail outlets across Montgomery County. Shoppers here read labels and ask where their food comes from. A clamshell of living microgreens harvested the day before sells itself at a market table, and the same product moves through small grocers and CSA boxes that want a hyperlocal story to tell.

The indoor angle is what makes this dependable. Maryland winters shut down field growing for months, but microgreens do not care what the weather is doing outside. A climate-controlled corner of your North Potomac home produces the same quality crop in January as it does in June, which means you are the supplier still standing when everyone else has gone dormant.

*If a year went by and the demand at Montgomery County farmers markets kept climbing while you were still only thinking about it, how would that sit with you?*

The math, in North Potomac prices

Microgreens wholesale to Montgomery County restaurants in the range of $25 to $40 per pound, and retail clamshells at market push the effective price higher still.

What that looks like in North Potomac square footage

*What would it mean for your week if the cold Maryland winter, the season when most local growers shut down, was actually your most profitable stretch instead of your slowest?*

Three things every working microgreen farm in North Potomac 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 North Potomac 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 North Potomac. 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 North Potomac grower starting today is not on their own.

What you are not buying

You are not buying a course. You are not buying a hype product. You are not buying seed from us, and you are not buying trays from us. We do not sell either. Grown Like A Pro is the operating system you run your North Potomac farm on. The growing happens in your basement.

North Potomac microgreen FAQ

How much can I make growing microgreens in North Potomac?
A working microgreen farm in North Potomac 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 North Potomac?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including North Potomac. 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 North Potomac?
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 North Potomac's climate. Vertical shelving is the fastest path to higher revenue per square foot.

Commercial proficiency, meaning you can run 50-plus trays per week without losing crops to mold or under-seeding, takes 60 to 90 days. 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 North Potomac?
For farmers market and direct-to-consumer sales in North Potomac, 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.

Restaurant wholesale in North Potomac runs $1.50 to $2.50 per ounce for standard varieties, $3 to $5 per ounce for specialty varieties like shiso, micro basil, or amaranth.
