MICROGREEN BUSINESS GUIDE · CORTLAND, IL

Start a microgreen business in Cortland, IL.

Most Cortland residents do not realize that a high-value crop can be grown indoors here without an acre of DeKalb County farmland. This is classic northern Illinois corn and soybean country, sitting right next to DeKalb and Sycamore and the university crowd that drives demand for fresh, local food. Microgreens are exactly the kind of high-margin product those kitchens and markets want and rarely find. The opening is that almost nobody nearby is growing them.

Quick Answer

You can start a microgreen business in Cortland with under $400 in initial equipment and grow it into a $1,000 to $2,900 per month side income within 90 days. Here is the local demand picture, the unit economics at Cortland wholesale prices, and the operating system used by working microgreen farms.

When a kitchen in DeKalb or Sycamore wants living micro greens cut that morning, how far is their current supplier actually based?

What Cortland buys today

Restaurants in and around DeKalb and Sycamore are the first buyers. Chefs serving the university town and surrounding communities want fresh pea shoots, radish, and micro herbs that hold up on the plate, and a Cortland grower who can deliver quickly becomes the local source they did not know existed.

Farmers markets and small grocers are the second channel. Shoppers across DeKalb County, including the steady student and faculty crowd, increasingly seek out local food, and microgreens sell fast at a market table because they are colorful, nutrient-dense, and priced strong per ounce.

The indoor angle is the deciding factor here. Northern Illinois winters end outdoor growing for months, but microgreens grow under lights in a spare room at a steady temperature year round. While field growers around Cortland wait out the cold, you keep cutting trays and keep supplying buyers with no other local option.

If a chef near the university or in Genoa could source fresh microgreens from a grower minutes away, what would that reliability be worth to them?

What that looks like in Cortland square footage

Have you noticed how northern Illinois winters shut down every outdoor grower around DeKalb County, leaving local kitchens with no fresh greens for months?

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

Cortland microgreen FAQ

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

How long does it take to learn to grow microgreens commercially?
Most growers in Cortland 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 Cortland?
For farmers market and direct-to-consumer sales in Cortland, 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 Cortland?
Restaurant wholesale in Cortland 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 Cortland restaurants currently buy.
