MICROGREEN BUSINESS GUIDE · LOMBARD, IL

Start a microgreen business in Lombard, IL.

Most Lombard residents do not realize that one of the highest-margin food businesses in DuPage County can run out of a spare bedroom. Known as the Lilac Village, Lombard sits in the heart of the western suburbs, surrounded by the dense dining of Elmhurst, Glen Ellyn, and the wider DuPage corridor along Roosevelt Road and the Illinois Prairie Path. Microgreens grow indoors from seed to harvest in seven to fourteen days, so the long Chicago winter that closes every outdoor grower never stops your harvest. The barrier to starting is far lower than people think.

Quick Answer

You can start a microgreen business in Lombard with under $400 in initial equipment and grow it into a $1,300 to $3,800 per month side income within 90 days. Here is the local demand picture, the unit economics at Lombard wholesale prices, and the operating system used by working microgreen farms.

What Lombard buys today

Lombard sits in one of the densest restaurant markets in the western suburbs, with kitchens across Elmhurst, Glen Ellyn, Villa Park, and Addison all within a short drive. These chefs plate for guests who notice quality and pay a premium for micro cilantro, sunflower shoots, and micro radish, especially when a local grower can guarantee a same-day harvest that no distributor can match.

DuPage County's farmers markets are among the best-attended in the Chicago suburbs, and Lombard's own market traditions draw shoppers who treat fresh greens as a staple. A clamshell that costs you under a dollar to produce sells for four to six dollars at a table, and the household demand for living trays compounds quickly into a repeat customer base.

The indoor angle is the quiet edge in Lombard. Chicago-area winters shut down every field operation for months, so a controlled indoor grow keeps producing the same in January as in July. You become the only local source of fresh greens during the dead season, and that scarcity is your pricing power.

What that looks like in Lombard square footage

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

Lombard microgreen FAQ

How much can I make growing microgreens in Lombard?
A working microgreen farm in Lombard 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 Lombard?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Lombard. 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 Lombard?
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 Lombard's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Lombard?
Grown Like A Pro is the operating system used by working microgreen farms in Lombard. 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 Lombard 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 Lombard?
For farmers market and direct-to-consumer sales in Lombard, 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 Lombard?
Restaurant wholesale in Lombard 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 Lombard restaurants currently buy.
