MICROGREEN BUSINESS GUIDE · FREMONT, CA

Start a microgreen business in Fremont, CA.

Most Fremont chefs do not know where their microgreens come from. The trays sitting in their walk-ins shipped in through Bay Area distributors and the freshness gap on the East Bay table is what a Fremont-based grower walks straight into. The operator who plants close to the kitchens, in Niles, Centerville, or near Warm Springs, is the one who locks the chef-driven accounts before anyone else shows up.

Quick Answer

You can start a microgreen business in Fremont with under $400 in initial equipment and grow it into a $2,500 to $7,500 per month side income within 90 days, even from a 600 square foot apartment. Here is the local demand picture, the unit economics at Fremont wholesale prices, and the operating system used by working microgreen farms.

If you walked through ten chef-driven restaurants between Niles and Warm Springs on a Tuesday and asked where their microgreens came from, how many do you think would say a grower inside Fremont? The honest answer is almost none, even in the heart of the East Bay tech corridor.

What Fremont buys today

Fremont sits in one of the most diverse dining markets in the Bay Area. The Indian, Afghan, Chinese, and Vietnamese restaurant scenes here are deep and chef-driven, and the modern American and farm-to-table corridor through Niles and Centerville has continued to expand. Microgreens move through high-end Indian and pan-Asian plates more than people realize, and almost all of that supply currently moves through Bay Area distributors.

The buyer profile extends past traditional restaurants. The Tesla and tech-corridor corporate catering layer is unusually large for a city of Fremont's size, and the wellness culture across the Tri-City area supports juice shops, acai bowl concepts, and natural grocers. Add the Centerville and Irvington farmers markets on weekends and direct-to-consumer is a real second channel.

The climate angle works in your favor. The Bay Area is mild outside but wholesale buyers want indoor-grown consistency, not weather-affected field product. A climate-controlled indoor space in a Fremont apartment, garage, or spare bedroom holds the same temperature in August as in February. A 5 by 10 foot footprint can carry both the restaurant route and the weekend market booth.

Every week you delay, another fifty trays of restaurant revenue gets locked up by a distributor truck rolling in from across the Bay. What does it cost you to be the second grower in your part of the Tri-City instead of the first?

The math, in Fremont prices

Fremont restaurant wholesale prices for microgreens sit at the upper end of the national range, with chef-driven Niles and Warm Springs accounts paying above standard wholesale because of the freshness gap. Here is what the unit economics look like at conservative Fremont 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 Fremont pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture the version of your week where Sunday is the planting day, Tuesday and Friday are restaurant deliveries inside the Tri-City, Saturday is the Centerville market, and the system on your phone tells you exactly which trays to cut and when. What changes about the rest of your week when the income side is on autopilot?

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

Fremont microgreen FAQ

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

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