MICROGREEN BUSINESS GUIDE · HARVEY, IL

Start a microgreen business in Harvey, IL.

Most Harvey residents do not realize how much demand for living greens sits across the dense south suburbs of Cook County. The town is surrounded by kitchens, households, and markets that already pay premium prices for fresh produce, and Chicago is a short ride north. Yet almost no one in Harvey is growing microgreens on a serious, repeatable schedule. That gap is the opportunity.

Quick Answer

You can start a microgreen business in Harvey with under $400 in initial equipment and grow it into a $1,100 to $3,600 per month side income within 90 days. Here is the local demand picture, the unit economics at Harvey wholesale prices, and the operating system used by working microgreen farms.

When you picture the kitchens working across Dolton and South Holland just minutes from your door, how many of them do you think are settling for greens trucked in days ago because no one local offered them fresher?

What Harvey buys today

Restaurants and private chefs across Harvey and the surrounding south suburbs go through garnish-grade greens constantly, and most are buying from broadline distributors delivering product that is already several days old. A local grower who can hand a chef in Dolton or Hazel Crest a tray cut that same morning becomes the obvious choice, because freshness and shelf life are exactly what those kitchens are losing money on right now.

Farmers markets and direct retail across the south suburbs reward sellers who show up with something the produce aisle cannot match. Microgreens are that product. Shoppers who already pay top dollar for organic greens will pay more for living trays harvested to order, and the dense Harvey, South Holland, and Markham population gives you a steady weekend outlet.

The indoor angle is what makes Harvey work twelve months a year. Chicagoland winters freeze outdoor growers out for months, but microgreens grow under lights in a spare room regardless of the weather. While field producers go dormant, you keep harvesting and keep your buyers, which is the entire point of growing indoors here.

If a buyer in Riverdale or Markham could get living trays cut the morning of service instead of bagged product from a distributor, what would stop them from switching to you?

The math, in Harvey prices

Across the Chicago south suburbs, wholesale microgreens move at roughly $25 to $40 per pound, and chef-direct trays often command even more.

What that looks like in Harvey square footage

A 10 by 10 foot room run on simple shelving in Harvey can hold enough rotating trays to supply several restaurant accounts and a weekend market booth at the same time.

Have you ever considered that Chicago's brutal winters, the same ones that shut down outdoor growing for half the year, are exactly why an indoor Harvey grower can name their price from November through March?

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

Harvey microgreen FAQ

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