MICROGREEN BUSINESS GUIDE · DETROIT, MI

Start a microgreen business in Detroit, MI.

Most Detroit chefs do not know where their microgreens come from. The trays sitting in their walk-ins shipped in from greenhouses outside the metro, and the freshness gap is exactly what a Detroit-based grower walks straight into. The operator who plants close to the kitchens, in Corktown, Midtown, or out in Ferndale, is the one who locks the chef-driven accounts before anyone else shows up.

Quick Answer

You can start a microgreen business in Detroit with under $400 in initial equipment and grow it into a $2,000 to $6,000 per month side income within 90 days, even from a 600 square foot apartment. Here is the local demand picture, the unit economics at Detroit wholesale prices, and the operating system used by working microgreen farms.

If you walked through ten chef-driven restaurants in Corktown or Midtown on a Tuesday and asked where their microgreens came from, how many do you think would say a grower inside Detroit? The honest answer is almost none, and the chefs are already noticing the wilt by day five.

What Detroit buys today

Detroit's food scene has been rebuilding in waves for the last decade, and the current chef-driven concept count across Corktown, Midtown, West Village, Eastern Market, and into Ferndale and Royal Oak is bigger than most aspiring growers realize. Tasting menus, modern American steakhouses, neo-bistros, and Coney-reinvented brunch concepts all use microgreens for plate finish, and almost all of that supply comes in from outside the city.

The buyer profile in Detroit is also unique because the urban-farming culture here is strong. Eastern Market on Saturday draws a customer who already understands and pays for hyper-local produce, and the natural grocery scene across the metro has the shelf space for prepacked clamshells. That means direct-to-consumer can run alongside restaurant wholesale without competing with it.

The climate works for an indoor grower. Detroit winters knock most regional outdoor production offline, which lengthens the supply chain for the distributors and ages the product on the way in. A heated basement or spare room in Detroit stays in the right temperature band year round, the heating cost is already in your rent or mortgage, and a 5 by 10 foot footprint can carry the entire operation.

Every week you delay, another fifty trays of restaurant revenue gets locked up by a distributor truck rolling in from out of state. What does it cost you to be the second grower in your part of the metro instead of the first?

The math, in Detroit prices

Detroit restaurant wholesale prices for microgreens sit in the mid national range, with chef-driven Corktown, Midtown, and Ferndale accounts paying above standard wholesale because of the freshness gap. Here is what the unit economics look like at conservative Detroit 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 Detroit pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Detroit 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 Detroit at standard wholesale prices. A two-car garage doubles it. A basement triples it.

Picture the version of your week where Sunday is the planting day, Tuesday and Friday are restaurant deliveries inside the metro, Saturday is Eastern Market, and the system on your phone tells you exactly which trays to cut and when. What changes about the rest of your week when the income side is on autopilot?

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

Detroit microgreen FAQ

How much can I make growing microgreens in Detroit?
A working microgreen farm in Detroit 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 MI?
Yes. In most of Michigan, 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 Michigan Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in Detroit?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Detroit. 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 Detroit?
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 Detroit's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Detroit?
Grown Like A Pro is the operating system used by working microgreen farms in Detroit. 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 Detroit 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 Detroit?
For farmers market and direct-to-consumer sales in Detroit, most growers operate under Michigan'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 Detroit?
Restaurant wholesale in Detroit 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 Detroit restaurants currently buy.
