MICROGREEN BUSINESS GUIDE · SUNNYVALE, CA

Start a microgreen business in Sunnyvale, CA.

Most Sunnyvale growers do not realize how favorable the Silicon Valley demographics are for a high-end microgreen operation. The city sits inside the densest tech-worker corridor in the country, with restaurants, corporate dining programs, and a consumer base that already pays premium for specialty produce. The Sunnyvale operator who plants close to those kitchens and campuses pays themselves first.

Quick Answer

You can start a microgreen business in Sunnyvale with under $400 in initial equipment and grow it into a $3,500 to $8,000 per month side income within 90 days. Here is the local demand picture, the unit economics at Silicon Valley wholesale prices, and the operating system used by working microgreen farms.

If you walked into five restaurants along Murphy Avenue or El Camino on a Tuesday and asked where their microgreens were grown, how many would point to a South Bay grower?

What Sunnyvale buys today

Sunnyvale sits inside one of the most concentrated higher-income markets in the United States, with the South Bay tech workforce, the chef-driven restaurant scene along Murphy Avenue, and the regional corporate dining programs at major tech campuses all consuming specialty produce at unusual volume. Local microgreens are almost custom-built for this demographic, and yet local supply is thin.

The Saturday farmers market scene across the South Bay is one of the strongest in the country, with year-round demand for specialty produce and a customer base willing to pay premium prices. Add the dense Asian, Indian, and Mediterranean food cultures that use a wider variety of microgreens than the standard American menu, and the variety mix a grower can sell is unusually broad.

For indoor growing, the Sunnyvale climate is one of the easiest in the country. Mild year-round temperatures mean a spare room or insulated garage holds the 65 to 75 degree window microgreens need with minimal climate control. Humidity is low enough to prevent most mold issues. The only real challenge is cost of space, which is exactly why a compact, high-revenue-per-square-foot operation makes sense here.

Every month you wait, another local restaurant or corporate dining program signs a 12-month agreement with a Salinas Valley distributor pulling product that already traveled. What does it cost you when the kitchens you wanted to sell to are already on someone else's invoice?

The math, in Sunnyvale prices

Sunnyvale restaurant and corporate dining wholesale prices for microgreens run well above the national average given Silicon Valley costs and the willingness to pay for genuinely local specialty produce. Here is what the unit economics look like at conservative Sunnyvale 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 Sunnyvale pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Imagine the version of your week where Sunday is the planting day, Tuesday is restaurant and corporate dining delivery across the South Bay, Saturday is the farmers market, and the system tells you exactly which trays to cut. What changes about the other four days when the income side runs on rails?

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

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.

Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Sunnyvale.
