MICROGREEN BUSINESS GUIDE · MADISON, WI

Start a microgreen business in Madison, WI.

Most Madison residents do not realize that this city, with one of the strongest local-food cultures in the Midwest, still imports most of its microgreens from out of state. The farm-to-table kitchens around the Capitol Square, the co-op shoppers, and the chef community that built the Dane County Farmers Market reputation all want truly local product. The Madison grower who steps up first stops competing on price the day they start.

Quick Answer

You can start a microgreen business in Madison with under $400 in initial equipment and grow it into a $2,500 to $7,000 per month side income within 90 days. Below is the local demand picture, the unit economics, and the operating system real microgreen farms run on.

If your city is already known for one of the best farm-to-table cultures in the country, why are the microgreens on most local plates not actually grown locally?

What Madison buys today

Madison is home to the Dane County Farmers Market, one of the largest producer-only markets in the United States, which means shoppers and chefs here are already conditioned to pay for genuinely local product. That is a huge head start for a new microgreen grower.

The food culture leans into farm-to-table, co-op grocery, university adjacent restaurants, and a strong locavore movement. All of those buyer types pay for trays harvested the same morning, and most of them quietly complain about the shelf life of what gets shipped in during shoulder season.

The Wisconsin winter is the real reason microgreens are an unusually good fit here. When the field season ends, demand for fresh local greens does not, and an indoor grower fills a gap that traditional farms cannot. That is six months a year of low competition revenue.

If Madison's strongest local-food advocates keep settling for out of state microgreens through winter because no one local supplies them, what does that say about the gap waiting to be filled?

The math, in Madison prices

Here is what the math looks like for a Madison grower selling at an upper-Midwest farm-to-table tier.

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 Madison pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture a January morning where the field farmers are dormant, the markets are quiet, and you are the only person in the county delivering fresh greens to three restaurants and a Saturday indoor market. What does that do to your annual income?

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

Madison microgreen FAQ

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