MICROGREEN BUSINESS GUIDE · BURLINGAME, CA

Start a microgreen business in Burlingame, CA.

Most Burlingame residents do not realize that the dense Burlingame Avenue restaurant scene is plating microgreens. The downtown core has built a tight dining identity around a walkable shopping street, but the supply chain still runs through distributors out of the area. The Burlingame grower who steps in first owns the avenue.

Quick Answer

You can start a microgreen business in Burlingame 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 at Burlingame wholesale prices, and the operating system used by working microgreen farms.

Walk into five restaurants on Burlingame Avenue on a Tuesday and ask where the microgreens were cut. How often does the answer point back to anywhere inside San Mateo County?

What Burlingame buys today

Burlingame Avenue is one of the densest concentrations of independent restaurants per block on the Peninsula, drawing diners from across the north county and beyond. The demographic skews high-income, food-aware, and willing to pay full retail without negotiation, which is the textbook buyer for a premium microgreen business.

The Sunday farmers market is one of the steadier ones on the north Peninsula, with a buyer base that already treats local sourcing as baseline. The juice and wellness culture along Broadway and the natural grocery channel layer in steady direct-to-consumer demand.

For indoor growing, the coastal-influenced climate is unusually friendly. Mild year-round temperatures keep a garage or spare-room grow space comfortably inside the productive window with minimal intervention, keeping electricity costs predictable and yields consistent.

If a grower in San Mateo or Millbrae locks down the Burlingame Avenue accounts in the next 60 days, what does that cost you over the next two years at premium downtown prices?

The math, in Burlingame prices

Burlingame sits at the upper end of California wholesale pricing, with chef-driven downtown accounts paying a real premium for genuinely same-day local trays. Here is what the unit economics look like at conservative Burlingame 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 Burlingame pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture the version of your year where Burlingame Avenue is on standing delivery, the Broadway corridor is on a second route, and the Sunday market is a routine cash channel. What does that free up in the rest of your life?

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

Burlingame microgreen FAQ

How much can I make growing microgreens in Burlingame?
A working microgreen farm in Burlingame produces $3,000 to $8,000 per month within 90 days of starting.

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 Burlingame?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Burlingame. 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 Burlingame?
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 Burlingame'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 Burlingame?
For farmers market and direct-to-consumer sales in Burlingame, 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.
