MICROGREEN BUSINESS GUIDE · HIGHLAND, IL

Start a microgreen business in Highland, IL.

Most Highland residents do not realize that sitting in eastern Madison County is an advantage, not a limit, when it comes to growing microgreens. The St. Louis Metro East spreads out to the west, full of kitchens and shoppers who rarely see a truly local supplier, and the town carries a strong Swiss-heritage food tradition of its own. Out here the land is known for corn, soybeans, and dairy, but almost no one is growing high-value living greens. That makes the field wide open.

Quick Answer

You can start a microgreen business in Highland with under $400 in initial equipment and grow it into a $1,000 to $3,300 per month side income within 90 days. Here is the local demand picture, the unit economics at Highland wholesale prices, and the operating system used by working microgreen farms.

When you think about the restaurants over in Troy and toward the Metro East that want a local story to tell their customers, who is actually supplying them with greens grown nearby instead of shipped in?

What Highland buys today

Chefs across the Metro East, from Troy to Glen Carbon, are constantly looking for a point of difference, and locally grown microgreens give them one they can put right on the menu. Highland sits close enough to deliver to those kitchens and far enough east that no one there is already serving them, which leaves the door open for a grower who shows up reliable and fresh.

Farmers markets and direct retail across Madison County and into Highland's own food-conscious community reward sellers who bring something the corn-and-soybean country does not produce. Microgreens stand out hard against typical farm-stand fare, and shoppers who appreciate real food will pay a premium for living trays cut to order rather than bagged greens from a chain store.

The indoor climate angle is decisive in southern Illinois. Winters here are hard on any outdoor operation, but microgreens grow under lights indoors no matter the season. While field growers shut down for months, a Highland grower keeps producing and keeps every account, turning the off-season into prime selling time.

If you set up at a market in Highland or Breese with trays you cut that morning, how do you think shoppers used to commodity produce would react to something that fresh?

The math, in Highland prices

What that looks like in Highland square footage

A 10 by 10 foot room on basic shelving in Highland can grow enough trays to cover a Metro East restaurant account and a Madison County market stand together.

Have you noticed that the same southern Illinois winters that end the outdoor season for everyone around you are exactly when an indoor Highland grower has no competition at all?

Three things every working microgreen farm in Highland 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 Highland 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 Highland. 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 Highland grower starting today is not on their own.

Highland microgreen FAQ

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