MICROGREEN BUSINESS GUIDE · JANESVILLE, WI

Start a microgreen business in Janesville, WI.

Most Janesville kitchens serving microgreens are split between out-of-town distributors and a handful of local growers stretched thin. The downtown Milwaukee Street kitchens and the surrounding chef-driven independents are mostly served by greens trucked in from Madison or Milwaukee. The Janesville grower who steps up first owns those accounts.

Quick Answer

You can start a microgreen business in Janesville with under $400 in initial equipment and grow it into a $1,800 to $5,000 per month side income within 90 days. Here is the local demand picture, the unit economics at Janesville wholesale prices, and the operating system used by working microgreen farms.

Walk into five independent restaurants in downtown Janesville on a Tuesday and ask where their microgreens come from. How often is the answer a person you could actually call by name?

What Janesville buys today

Janesville has a steadily redeveloping downtown along Milwaukee Street and the Rock River, with chef-driven independents adding ingredient-conscious concepts each year. The city's position between Madison and the Illinois border puts a Janesville-based grower in a strong delivery position for both regional and local accounts.

The Janesville Farmers Market in downtown pulls a willing-to-pay weekend customer base across Rock County. The catering channel through corporate offices, wedding venues along the river, and the surrounding suburbs of Milton and Edgerton adds steady volume that compounds quickly for a single operator.

For indoor growing, the consideration is the long, cold Wisconsin winter. A basement, insulated garage, or spare room holds the 65 to 75 degree window microgreens want, and Rock County wholesale demand covers the energy math at standard pricing.

Every week you wait, another Janesville kitchen settles into a distributor's standing invoice. What does it cost when the restaurants you wanted as anchor accounts are already on someone else's truck route?

The math, in Janesville prices

Janesville restaurant wholesale prices for microgreens sit in the standard Midwest tier, with chef-driven and event-catering accounts paying for cut-to-order local product. Here is what the unit economics look like at conservative Janesville numbers.

Trays per week

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

Picture the week where Sunday is planting day, Tuesday is delivery along Milwaukee Street, Saturday is the Janesville Farmers Market, and the app tells you exactly which trays to cut. What changes about your weekdays when the harvest schedule is locked?

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

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.

What microgreens sell best in Janesville?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Janesville.

Specialty varieties like amaranth and shiso command premium pricing from chef-driven restaurants.

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 Janesville's climate. Vertical shelving is the fastest path to higher revenue per square foot.

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 Janesville?
For farmers market and direct-to-consumer sales in Janesville, 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.
