MICROGREEN BUSINESS GUIDE · COMMERCE, CA

Start a microgreen business in Commerce, CA.The app starts at only $3 a month.

Most Commerce residents do not realize how little of the fresh produce moving through their city is actually grown nearby. This is an industrial city built around manufacturing, distribution, and a major casino-hotel, yet the microgreens served here are mostly trucked in from out of the area. The grower in Commerce who fixes that, with trays cut the morning of delivery, is the one who gets paid first.

Quick Answer

You can start a microgreen business in Commerce with under $400 in initial equipment and grow it into a $2,500 to $6,500 per month side income within 90 days. Here is the local demand picture, the unit economics, and the operating system used by working microgreen farms.

When you think about the restaurants serving the hotel and industrial districts of Commerce, how many of them are serving microgreens grown anywhere near the city?

What Commerce buys today

Commerce is, true to its name, an industrial and logistics hub in southeast LA County, with a small residential population but a large daytime workforce and a major casino-hotel and outlet shopping draw. That mix means a steady flow of hospitality and dining demand that a local grower can serve.

The city sits at the crossroads of Vernon, East Los Angeles, Montebello, and Downey, so a grower here can reach an enormous spread of kitchens and food businesses inside a short drive. The dense surrounding population and the food culture of the corridor both favor fresh, specialty produce.

The climate is mild inland coastal, with summer heat as the main growing variable. The city's industrial character also means workshop and warehouse space is more available, which can let a grower scale beyond a garage when the accounts are there. A controlled space holds the 65 to 75 degree window cheaply year round.

Every week you wait, another kitchen in the corridor locks into a distributor habit. What does it cost you when the accounts near Commerce are already on someone else's invoice?

The math, in Commerce prices

Here is what the numbers look like for a Commerce grower at a southeast LA County metro price tier.

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 Commerce pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Commerce 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 Commerce at standard wholesale prices. A two-car garage doubles it. A basement triples it.

What would your week look like six months from now if planting, a delivery loop through the surrounding cities, and a hotel account all ran on a schedule the app handed you, instead of guesswork?

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

Commerce microgreen FAQ

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

Most growers in Commerce 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 Commerce?
For farmers market and direct-to-consumer sales in Commerce, 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 Commerce?
Restaurant wholesale in Commerce 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.
