MICROGREEN BUSINESS GUIDE · CAMBRIDGE, MA

Start a microgreen business in Cambridge, MA.

Most Cambridge residents do not realize how few serious local microgreen growers actually serve the Cambridge and Boston chef bench. Kendall Square, Harvard Square, Central Square, and the Boston dining corridor across the river all run plate-driven menus with garnish budgets to match, yet a surprising share of the greens still ride in from out of state. The Cambridge grower who steps up owns a category nobody is actually competing for.

Quick Answer

You can start a microgreen business in Cambridge with under $400 in initial equipment and grow it into a $3,500 to $9,000 per month side income within 90 days. Here is the local demand picture, the unit economics at Greater Boston wholesale prices, and the operating system used by working microgreen farms.

When you eat in Kendall Square or Central Square and notice microgreens on the plate, how often do you actually find out a local grower delivered them that morning?

What Cambridge buys today

Cambridge sits across the river from Boston with one of the densest chef-driven restaurant footprints in New England between the two cities. Kendall, Harvard, Central, and Inman Squares all run modern American and chef-driven menus, plus the Boston Back Bay, Seaport, and South End corridors are all inside a short drive across the bridges.

The university and biotech demographic gives Cambridge a young, food-curious, higher-income customer base that supports both farmers market sales and direct delivery. The Cambridge and Somerville market network draws steady weekend traffic from across the metro.

New England's four-season climate is the indoor consideration. A basement, insulated garage, or spare bedroom with a small heater for winter and a window AC and dehumidifier for summer holds the 65 to 75 degree window microgreens want twelve months a year, and indoor real estate is the main constraint to think through.

Every month another Cambridge or Boston chef signs a contract with a distributor truck rolling product in from somewhere else. What does it cost you when those accounts get locked in before you ever pick up the phone?

The math, in Cambridge prices

Greater Boston wholesale prices for microgreens run well above the national average, with chef-driven accounts in Cambridge and across the river paying premium for genuinely local cut-to-order product. Here is what the unit economics look like at conservative Cambridge numbers.

Startup cost

$400

Trays, soil, seed, lights. Used gear cuts this in half.

Per-tray net

$20-$30

After seed, soil, packaging, delivery.

Trays per week

100

Target for $3K-$5K/mo at Cambridge pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Cambridge square footage

A 10 by 10 foot room with two vertical shelving units holds 60 to 80 active trays. That is enough to produce $3,000 to $5,000 per month in Cambridge at standard wholesale prices. A two-car garage doubles it. A basement triples it.

Picture the week where Sunday is planting day, Tuesday is the Cambridge and Somerville route, Friday is Back Bay and the Seaport, Saturday is the market, and the system tells you exactly what to cut. What does the rest of your life look like once the business runs itself?

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

Cambridge microgreen FAQ

How much can I make growing microgreens in Cambridge?
A working microgreen farm in Cambridge 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 MA?
Yes. In most of Massachusetts, 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 Massachusetts Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in Cambridge?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Cambridge. 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 Cambridge?
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 Cambridge's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Cambridge?

How long does it take to learn to grow microgreens commercially?
Most growers in Cambridge 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 Cambridge?
For farmers market and direct-to-consumer sales in Cambridge, most growers operate under Massachusetts'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 Cambridge?
Restaurant wholesale in Cambridge 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 Cambridge restaurants currently buy.
