MICROGREEN BUSINESS GUIDE · SAN PABLO, CA

Start a microgreen business in San Pablo, CA.

Most people in San Pablo never think about where the city's fresh greens come from. The diners, taquerias, and family kitchens here are served almost entirely by distributors trucking product in from out of the area, cut long before it lands. The San Pablo grower who delivers same-morning trays owns a lane no one local is running yet.

Quick Answer

You can start a microgreen business in San Pablo with under $400 in initial equipment and grow it into a $3,000 to $8,000 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.

If you asked the independent kitchens around San Pablo Avenue where their fresh garnish comes from, how many could name a grower from right here instead of a delivery route?

What San Pablo buys today

San Pablo sits in West Contra Costa, a dense, working community with a strong Latino food culture and a tight cluster of independent restaurants along its main corridors. Those owner-run kitchens make their own buying decisions, which means a local grower can talk directly to the person who signs the check instead of fighting through a corporate procurement office.

The city is wedged between Richmond and the I-80 corridor, putting dozens of additional restaurants and cafes within a short drive of any San Pablo grow space. That density lets one operator serve multiple towns on a single delivery loop.

The bay-influenced climate stays mild most of the year, so a modest indoor setup in a spare room or garage holds steady germination temperatures without heavy heating or cooling, keeping your power bill predictable and your yields consistent.

Every month you wait, another distributor renews its grip on the kitchens around you. What does it cost you when the owners you wanted to supply are already locked into someone else's invoice?

The math, in San Pablo prices

Here is what the numbers look like for a San Pablo grower selling into the West Contra Costa restaurant market.

Startup cost

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 San Pablo pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Imagine the version of your week where the independent kitchens within a few miles of San Pablo Avenue all run on your trays, and a system tells you exactly which crops to seed and cut. What would that steady wholesale base change about your month?

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

San Pablo microgreen FAQ

How much can I make growing microgreens in San Pablo?
A working microgreen farm in San Pablo 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 San Pablo?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including San Pablo. 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 San Pablo?
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 San Pablo'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 San Pablo?
For farmers market and direct-to-consumer sales in San Pablo, 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.

Restaurant wholesale in San Pablo 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.
