MICROGREEN BUSINESS GUIDE · PLYMOUTH, MI

Start a microgreen business in Plymouth, MI.

Most Plymouth residents do not realize how shallow the local microgreen supply actually is for one of the prettiest downtown restaurant strips in western Wayne County. The chef-owned spots around Kellogg Park and Main Street are mostly served by greens that already lost a week of life in a distributor truck. The Plymouth grower who steps up first locks in those accounts.

Quick Answer

You can start a microgreen business in Plymouth with under $400 in initial equipment and grow it into a $2,500 to $6,500 per month side income within 90 days. Here is the local demand picture, the unit economics at Plymouth wholesale prices, and the operating system used by working microgreen farms.

Walk into five chef-owned restaurants around Kellogg Park in Plymouth on a Tuesday and ask where their microgreens come from. How often is the answer a person you could actually call by name?

What Plymouth buys today

Plymouth's downtown district around Kellogg Park is a walkable, restaurant-dense corridor that pulls diners from across western Wayne and southern Oakland counties. The chef-driven and upscale-casual restaurants downtown care about ingredient quality and run the kind of plate presentation that microgreens upgrade obviously.

The Plymouth Farmers Market is a longstanding civic fixture and pulls a willing-to-pay weekend customer base. The surrounding demographic skews higher-income and ingredient-focused, with strong demand from private chefs and event caterers serving the Plymouth and Canton wedding venues.

For indoor growing, the consideration is winter heating in a four-season climate. A finished basement, insulated garage, or spare room holds the 65 to 75 degree window microgreens want, and the premium pricing across these accounts covers the energy math easily.

Every week you wait, another downtown Plymouth chef quietly signs onto a distributor's standing order. What does it cost when the kitchens you wanted as anchor accounts are already supplied by someone else?

The math, in Plymouth prices

Plymouth restaurant wholesale prices for microgreens trend toward the mid-tier with chef-driven and event-catering accounts paying premium for cut-to-order local product. Here is what the unit economics look like at conservative Plymouth 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 Plymouth pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Imagine the week where Sunday is planting day, Tuesday is delivery around Kellogg Park and out to Northville, Saturday is the Plymouth Farmers Market, and the app tells you exactly which trays to cut. What changes about your weekdays when the harvest schedule is on rails?

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

Plymouth microgreen FAQ

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

Most growers in Plymouth 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 Plymouth?
For farmers market and direct-to-consumer sales in Plymouth, 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 Plymouth?
Restaurant wholesale in Plymouth 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.
