MICROGREEN BUSINESS GUIDE · LONDON, OH

Start a microgreen business in London, OH.

Most London residents do not realize the most profitable square footage in Madison County might be a spare room with a few shelves. London is the Madison County seat, set in the flat, productive farm country west of Columbus near West Jefferson and within easy reach of Hilliard and Grove City. That farmland grows commodity crops by the acre, but almost none of the chef-grade specialty greens local and metro kitchens actually want. Microgreens close that gap while the fields run on a single yearly cycle.

Quick Answer

You can start a microgreen business in London with under $400 in initial equipment and grow it into a $800 to $2,300 per month side income within 90 days. Here is the local demand picture, the unit economics at London wholesale prices, and the operating system used by working microgreen farms.

*When you look at how Madison County's ground pours everything into corn and soybeans, what would it mean to grow a fresh crop that yields every week and sells straight to local kitchens?*

What London buys today

Restaurants and chefs are the first dependable buyers. Independent kitchens in London and the nearby west Columbus suburbs build plates that call for a fresh garnish, and right now that product arrives aged from a distributor. A grower who can hand a chef pea shoots or radish microgreens within hours of cutting offers a freshness no truck out of Columbus can match.

Farmers markets and small retail fill out the week. Madison County shoppers already turn out for local produce, and a clamshell of sunflower or broccoli microgreens is an easy add at a market table or small grocer in a region defined by row crops. Regulars come back fast once they taste how much fresher a same-week cut is than the chain-store option.

The indoor-climate angle keeps the income steady year round. Central Ohio swings from humid summers to hard winters, but a microgreen rack lives indoors at a constant temperature. While the surrounding fields and gardens sleep through the cold, you keep cutting trays and invoicing the kitchens that stay open.

*If a chef in Hilliard or Grove City could get microgreens cut that morning instead of trucked in days old, how much do you think that freshness would be worth on the plate?*

The math, in London prices

Wholesale microgreens run roughly $25 to $40 per pound to Madison County and west Columbus kitchens, with live trays and market clamshells lifting the per-tray return further.

What that looks like in London square footage

A 10 by 10 foot room in London holds enough rack space to keep several area accounts supplied with fresh-cut microgreens every week of the year.

*Given how central-Ohio winters lock the fields down for months, have you considered what an indoor crop that ignores the cold could add to your income?*

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

London microgreen FAQ

How much can I make growing microgreens in London?
A working microgreen farm in London 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 OH?
Yes. In most of Ohio, 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 Ohio Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in London?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including London. 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 London?
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 London's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in London?
Grown Like A Pro is the operating system used by working microgreen farms in London. 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 London 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 London?
For farmers market and direct-to-consumer sales in London, most growers operate under Ohio'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 London?
Restaurant wholesale in London 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 London restaurants currently buy.
