MICROGREEN BUSINESS GUIDE · SAN RAMON, CA

Start a microgreen business in San Ramon, CA.

Most San Ramon residents do not realize how little of the produce served at restaurants in City Center and Bishop Ranch was grown anywhere nearby. The dining scene supporting one of the largest business parks in California still imports its microgreens from regional distributors. The San Ramon grower who closes that gap owns a market currently served by trucks rolling in from far away.

Quick Answer

You can start a microgreen business in San Ramon with under $400 in initial equipment and grow it into a $2,800 to $7,500 per month side income within 90 days. Here is the local demand picture, the unit economics at San Ramon wholesale prices, and the operating system used by working microgreen farms.

Walk into five restaurants in City Center or near Bishop Ranch and ask where the microgreens on the plate came from. How often does the answer point to a grower anywhere inside the Tri-Valley?

What San Ramon buys today

San Ramon is anchored by one of the largest office parks in Northern California and a high-income residential base, which together drive a dining scene heavy on lunch traffic and chef-driven dinner concepts. The City Center development concentrated the restaurant base in a way that makes a single delivery route highly efficient for a local grower.

The Saturday farmers markets across the Tri-Valley pull a willing-to-pay buyer base, and the juice and wellness culture serving the office-park population layers in steady direct-to-consumer demand. The natural grocery channel rounds out the picture.

For indoor growing, the climate is forgiving most of the year. Summer heat is the main consideration, which a window AC in a garage or spare room handles. The rest of the year, a small footprint stays inside the productive temperature range with minimal effort.

If another grower over in Pleasanton or Dublin locks in the City Center and Bishop Ranch accounts in the next 60 days, what does that cost you over the next two years in walked-away wholesale revenue?

The math, in San Ramon prices

San Ramon sits in the mid to upper tier of California wholesale pricing, with Tri-Valley chef-driven and office-park lunch accounts paying a real premium for genuinely local cut-to-order trays. Here is what the unit economics look like at conservative San Ramon 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 San Ramon pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

What does your year look like when the City Center kitchens, the Bishop Ranch lunch concepts, and the Saturday market are all running on standing delivery? In a market this concentrated, that is operational consistency, not ambition.

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

San Ramon microgreen FAQ

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

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