MICROGREEN BUSINESS GUIDE · ROMULUS, MI

Start a microgreen business in Romulus, MI.

Most Romulus kitchens serving microgreens are split between out-of-town distributors and a handful of local growers stretched thin. The hotels, banquet halls, and chef-driven independents within a 10 minute drive of the airport are mostly served by greens. The Romulus grower who steps up first owns those accounts.

Quick Answer

You can start a microgreen business in Romulus 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 Romulus wholesale prices, and the operating system used by working microgreen farms.

Walk into five hotel restaurants or independent kitchens near the airport corridor in Romulus on a Tuesday and ask where their microgreens come from. How often is the answer a local grower instead of a national distributor?

What Romulus buys today

Romulus sits directly next to Detroit Metro Airport, which produces a hospitality economy denser than most growers expect: hotel restaurants, banquet halls, catering kitchens, and corporate event services that all use fresh microgreens routinely. A grower based here can serve the entire airport-adjacent corridor inside a 15 minute drive.

The catering channel for airline crew hospitality, corporate travel, and wedding events at the larger hotels and banquet venues adds steady recurring volume. The surrounding Westland, Romulus, and Taylor restaurant base broadens the wholesale ceiling further.

For indoor growing, the consideration is winter heating in a long Michigan cold season. A basement, insulated garage, or spare room holds the 65 to 75 degree window microgreens want, and the airport-corridor wholesale density covers the energy math easily.

Every week you wait, another airport-corridor hotel or banquet kitchen settles into a standing distributor invoice. What does it cost when the highest-volume accounts in your delivery radius are already supplied by someone else?

The math, in Romulus prices

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

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Romulus 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 Romulus 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 to the airport-corridor hotels, Saturday is a market booth, and the app tells you exactly which trays to cut. What changes about your weekdays when the route is locked in?

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

Romulus microgreen FAQ

How much can I make growing microgreens in Romulus?
A working microgreen farm in Romulus 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 Romulus?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Romulus. 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 Romulus?
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 Romulus'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 Romulus?
For farmers market and direct-to-consumer sales in Romulus, 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.

Restaurant wholesale in Romulus 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.
