MICROGREEN BUSINESS GUIDE · POMONA, CA

Start a microgreen business in Pomona, CA.

Most Pomona growers do not realize they sit at the crossroads of the Inland Empire and east Los Angeles County, with reach into Claremont, Diamond Bar, the Cal Poly and Claremont Colleges restaurant layer, and the chef-driven independents along the downtown Pomona Arts Colony. The grower who builds a clean delivery route into the Inland Empire and east LA first locks the kind of standing weekly orders that fund a real income.

Quick Answer

A focused microgreen operation in Pomona can realistically reach $2,500 to $6,000 per month in net revenue within 90 to 120 days by serving Inland Empire chef-driven independents, college-town kitchens, and direct-to-consumer customers at the metro's tier-2 Southern California price range.

When you think about the Pomona and Claremont restaurants you actually eat at, how many of them are plating microgreens that almost certainly came in on a truck from a Los Angeles distributor?

What Pomona buys today

Pomona sits at the gateway to the Inland Empire, with the Claremont college town next door driving steady chef-driven independent demand along the Claremont Village, the Diamond Bar and Walnut country club layer adding catering volume, and the downtown Pomona Arts Colony pulling a growing chef-driven independent crowd. Mexican, contemporary American, and farm-to-table kitchens plate microgreens nightly across the corridor.

The climate is among the friendliest in the country for indoor growing. Year-round mild weather with hot dry summers keeps heating and cooling costs predictable, and a garage or spare bedroom can run twelve months with low overhead. Outdoor herb gardening at scale is unreliable in summer heat, which pushes chefs toward indoor suppliers who hit the same harvest day every week.

Add the Pomona Farmers Market downtown, the Claremont Farmers and Artisans Market, the rotating Inland Empire markets, and a growing wellness and gym layer pulling juice bar demand across the corridor, and a beginner has three real channels to test from week one.

If Los Angeles distributors keep cornering the Inland Empire restaurant routes for another year, how much harder does it get to break in once those chefs are locked into a supplier they already trust?

The math, in Pomona prices

Pomona and the Inland Empire wholesale prices for microgreens sit in the tier-2 Southern California range. Here is what the unit economics look like at conservative Pomona numbers.

Startup cost

$400

Trays, soil, seed, lights. Used gear cuts this in half.

Per-tray net

$20-$30

After seed, soil, packaging, delivery.

Trays per week

100

Target for $3K-$5K/mo at Pomona pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Pomona square footage

A 10 by 10 foot room with two vertical shelving units holds 60 to 80 active trays. That is enough to produce $3,000 to $5,000 per month in Pomona at standard wholesale prices. A two-car garage doubles it. A basement triples it.

What does it look like for you when a Claremont or downtown Pomona chef texts you for a same-week order and you already know the harvest day and the gram count before you reply?

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

Pomona microgreen FAQ

How much can I make growing microgreens in Pomona?
A working microgreen farm in Pomona 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 CA?
Yes. In most of California, 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 California Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in Pomona?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Pomona. 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 Pomona?
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 Pomona's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Pomona?

How long does it take to learn to grow microgreens commercially?
Most growers in Pomona 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 Pomona?
For farmers market and direct-to-consumer sales in Pomona, most growers operate under California'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 Pomona?
Restaurant wholesale in Pomona 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.
