MICROGREEN BUSINESS GUIDE · WOOD RIVER, IL

Start a microgreen business in Wood River, IL.

Most Wood River residents do not realize that a small indoor crop can quietly out-earn a much larger garden. This Madison County city sits in the Riverbend area near the Mississippi, a short drive from the busier markets and restaurants of Alton, Godfrey, and Glen Carbon, with the St. Louis metro just across the river. That regional demand is exactly what a microgreen grower needs, because buyers are close enough to serve and the local supply is thin. A few people in the area are already growing trays of greens in a spare room and turning them into steady extra income.

Quick Answer

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

When you think about the restaurants and grocers over in Alton and Godfrey, what is keeping a grower right here in Wood River from being the fresh-greens supplier they call first?

What Wood River buys today

Restaurants and caterers across the nearby Alton and Godfrey area pay a premium for fresh micro-herbs and shoots that arrive the same day they are cut, and in a smaller market a reliable local grower stands out fast. When the alternative is product that rides a truck for days, a same-week delivery from minutes away wins the account.

With the St. Louis metro just across the river, how much demand for genuinely fresh local greens do you think goes unmet in this part of Madison County?

The math, in Wood River prices

What would it do for your income if buyers in East Alton and Bethalto started sourcing their micro-herbs from you instead of trucking them in?

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

Wood River microgreen FAQ

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

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 Wood River?
For farmers market and direct-to-consumer sales in Wood River, 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.

Restaurant wholesale in Wood River 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.
