MICROGREEN BUSINESS GUIDE · MCHENRY, IL

Start a microgreen business in McHenry, IL.

Most McHenry residents do not realize that living up in McHenry County, along the Fox River and the Chain O'Lakes, puts them in a market full of restaurants, resorts, and weekend visitors who all want fresh food. While the chain grocers truck in greens that wilt on the way, a tray grown right here in McHenry is harvested the morning it sells. With Fox Lake, Johnsburg, and the whole lake-country tourism scene nearby, the demand for ultra-fresh microgreens is already here. Most people just have not connected the dots.

Quick Answer

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

When the Chain O'Lakes fills up with weekend visitors and the restaurants along the Fox River scramble to keep up, what does it tell you that their specialty greens are still trucked in from far away instead of grown right here in McHenry?

What McHenry buys today

Chefs around the Chain O'Lakes and the Fox River corridor use microgreens for plating, especially during the busy boating and tourism season. Restaurants in McHenry, Fox Lake, and Johnsburg want pea shoots, radish, and micro-cilantro delivered fresh rather than trucked in half-dead. A local grower who can hand-deliver the same day has an edge no national distributor can match.

Farmers markets across McHenry County move microgreens fast, and the lake-country weekend crowd adds a steady stream of shoppers who pay for quality. Selling clamshells directly to families in McHenry, Island Lake, and Lakemoor keeps the full margin in your pocket, and weekly regulars build recurring income quickly.

Because microgreens grow indoors under lights, the long northern Illinois winter that kills every outdoor plot becomes your advantage. While other growers go dormant for half the year, you keep harvesting in a climate-controlled room, charging premium off-season prices when fresh local greens are nearly impossible to find anywhere near McHenry.

If a lakeside restaurant near Fox Lake or Johnsburg is already paying a distributor for micro-arugula that has spent days on a truck, what would have to change for them to buy from a grower right here in McHenry County?

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

McHenry microgreen FAQ

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

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