MICROGREEN BUSINESS GUIDE · ANTIOCH, CA

Start a microgreen business in Antioch, CA.

Most Antioch residents do not realize they sit at the east end of the Bay Area food market with quick reach into Concord, Walnut Creek, and the wider East Bay chef bench. The combined market buys microgreens daily, and a surprising share of the supply still rolls in from far away. The Antioch grower with a smart route owns logistics that nobody from outside the East Bay can match.

Quick Answer

You can start a microgreen business in Antioch with under $400 in initial equipment and grow it into a $2,500 to $7,000 per month side income within 90 days. Here is the local demand picture, the unit economics at East Bay wholesale prices, and the operating system used by working microgreen farms.

When you eat in Walnut Creek or Concord and notice microgreens on the plate, how often do you actually find out an East Contra Costa grower delivered them that morning?

What Antioch buys today

Antioch sits at the east end of Contra Costa County with quick access along the highway corridor into Concord, Pleasant Hill, Walnut Creek, and the broader East Bay chef bench. That puts a working grower inside reach of a real chef-driven restaurant footprint plus the Brentwood and Discovery Bay corridors that round out the local market.

The East Bay's farm-to-table expectation runs strong, which means a local grower walks into a market where the question is not whether to buy local but whose local product is best on the day. That is one of the easiest sales conversations in the business when freshness is the differentiator.

The Bay Area's mild climate is forgiving for indoor growing. A spare bedroom or insulated garage holds the 65 to 75 degree window microgreens want with very little climate equipment, and the long farmers market season across the East Bay gives the direct-to-consumer side a steady channel year round.

Every month another East Bay chef signs a contract with a distributor truck. What does it cost you over a year of accounts you never even picked up the phone to pitch?

The math, in Antioch prices

East Bay wholesale prices for microgreens run well above the national average, with chef-driven accounts in Walnut Creek and across Contra Costa paying premium for genuinely local cut-to-order product. Here is what the unit economics look like at conservative Antioch 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 Antioch pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture the week where Sunday is planting day, Tuesday is the Walnut Creek route, Friday is Concord and Brentwood, Saturday is the market, and the system tells you exactly what to cut. What does the rest of your life look like once the business actually runs on a system?

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

Antioch microgreen FAQ

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

How long does it take to learn to grow microgreens commercially?
Most growers in Antioch 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 Antioch?
For farmers market and direct-to-consumer sales in Antioch, 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 Antioch?
Restaurant wholesale in Antioch 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 Antioch restaurants currently buy.
