MICROGREEN BUSINESS GUIDE · POTOMAC, MD

Start a microgreen business in Potomac, MD.

Most Potomac residents do not realize that one of the highest-margin food businesses in the country can run from a spare room in an affluent suburb. Potomac is among the wealthiest communities in Montgomery County, set along the river near Bethesda and Rockville, where chefs and shoppers expect the best and pay for it. Microgreens fit that market perfectly. They grow in days, command top prices per ounce, and need no land whatsoever.

Quick Answer

You can start a microgreen business in Potomac with under $400 in initial equipment and grow it into a $1,800 to $4,500 per month side income within 90 days. Here is the local demand picture, the unit economics at Potomac wholesale prices, and the operating system used by working microgreen farms.

*When you picture the chefs working the kitchens around Bethesda and Rockville, how many do you think are settling for greens trucked in from far away simply because no one local offers them a better option?*

What Potomac buys today

The restaurant trade is the natural first door. Potomac sits among the most affluent zip codes in the nation, and chefs across the Bethesda and Rockville corridor compete hard on presentation. A chef who needs pea shoots or micro radish on short notice cannot wait on a distributor, so a local grower delivering that morning becomes the obvious choice.

Then there are the farmers markets and upscale retailers across Montgomery County. Shoppers here read labels and ask exactly where their food comes from. A clamshell of living microgreens harvested the day before sells itself at a market table and moves easily through small grocers and CSA boxes.

The indoor angle is what makes this dependable. Maryland winters shut down field growing for months, but microgreens do not care what the weather does outside. A climate-controlled corner of your Potomac home grows the same quality crop in January as in June, leaving you the supplier still standing when others have gone dormant.

*If the demand at Montgomery County markets kept climbing while a grower in North Potomac or Travilah quietly claimed those accounts, how would that sit with you a year from now?*

The math, in Potomac prices

Microgreens wholesale to Montgomery County restaurants in the range of $26 to $42 per pound, and retail clamshells at market push the effective price higher still.

What that looks like in Potomac square footage

A 10 by 10 foot room, run well, can produce enough trays each week to supply several Potomac and Bethesda accounts at the same time.

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

Three things every working microgreen farm in 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 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 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 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 Potomac farm on. The growing happens in your basement.

Potomac microgreen FAQ

How much can I make growing microgreens in Potomac?
A working microgreen farm in 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 Potomac?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including 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 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 Potomac's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Potomac?
Grown Like A Pro is the operating system used by working microgreen farms in Potomac. It handles seed density math, watering schedules, harvest timing, inventory, customer orders, and the financial side. Free 30-day trial with no credit card.
How long does it take to learn to grow microgreens commercially?
Most growers in Potomac are selling their first trays within 30 days of starting. 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 Potomac?
For farmers market and direct-to-consumer sales in 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.
How do I price microgreens to restaurants in Potomac?
Restaurant wholesale in 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. Sell by the pound for repeat accounts. Local fresh commands a premium over the shipped-in product that most Potomac restaurants currently buy.
