MICROGREEN BUSINESS GUIDE · WASHINGTON, IL

Start a microgreen business in Washington, IL.The app starts at only $3 a month.

Most Washington residents do not realize how much fresh-produce demand sits just across the river in the Peoria metro. This is Tazewell County, near Morton and East Peoria, with the whole greater Peoria market a short drive away. The surrounding land grows corn and soybeans, so specialty produce like microgreens has almost no local grower. For a home operation, that absence is the whole opportunity.

Quick Answer

You can start a microgreen business in Washington with under $400 in initial equipment and grow it into a $1,000 to $2,700 per month side income within 90 days. Here is the local demand picture, the unit economics at Washington wholesale prices, and the operating system used by working microgreen farms.

When you think about the restaurants across the Peoria metro, who do you figure is supplying their microgreens if so few local growers exist?

What Washington buys today

Restaurants and chefs across the Peoria metro are the first market. East Peoria, Morton, and the broader Peoria dining scene keep independent kitchens busy, and chefs want garnish-quality microgreens that arrive alive, not days old from a distributor. A local grower offering same-morning delivery becomes the easy yes.

Farmers markets and direct retail fill out the demand. Tazewell County and the Peoria area have active markets where shoppers favor local food, and a $4 to $5 clamshell of sunflower or radish microgreens sells well beside the seasonal produce. A couple of market stalls plus a grocery or co-op account builds a steady weekly route.

The indoor-climate angle is the dependable backbone. Washington winters are cold and shut down outdoor growing, but microgreens grow under lights on a shelf no matter the weather. You stay in production in February and become the supplier still delivering fresh greens when seasonal county farms have gone dark.

If a chef in East Peoria or Morton could text one nearby grower for a same-day delivery instead of waiting on a Chicago or St. Louis truck, how much is that freshness worth?

The math, in Washington prices

Wholesale microgreens fetch roughly $22 to $38 per pound in the Peoria market, and one healthy tray of pea or sunflower can yield over a pound.

What that looks like in Washington square footage

A 10 by 10 foot room in Washington holds enough shelving to run dozens of trays on rotation, turning a spare bedroom into a real second income.

What would it change for your year if a 10 by 10 room kept producing income through a cold central-Illinois winter, while every field around you sat frozen?

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

Washington microgreen FAQ

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