MICROGREEN BUSINESS GUIDE · SAN JOSE, CA

Start a microgreen business in San Jose, CA.

Most San Jose growers do not realize the city sits inside one of the highest income, highest food-spend zip clusters in the country, and the local microgreen supply chain has not caught up. Between Santana Row, Willow Glen, downtown San Pedro Square, and the chef-driven kitchens scattered across the South Bay, hundreds of plates need finishing greens every night. The grower who serves Silicon Valley first holds the kind of accounts that fund a real income.

Quick Answer

You can launch a microgreen business in San Jose with under $500 in startup equipment and grow it to $3,500 to $8,000 per month in net revenue within 90 to 120 days. Here is the South Bay demand picture, the unit economics at Silicon Valley wholesale prices, and the operating system working farms run on.

If you walked into five chef-driven restaurants between Willow Glen and Santana Row this week and asked where their microgreens were cut, how many would point to a grower inside Santa Clara County?

What San Jose buys today

San Jose anchors the South Bay food scene with a mix of upscale steakhouses, modern Vietnamese, contemporary Mexican, and a long bench of chef-driven independents across Santana Row, downtown, and Willow Glen. Microgreens are baseline garnish on tasting menus and increasingly standard on lunch and brunch plates across the metro.

The demographic profile is the cleanest microgreen buyer profile in the country. Tech salaries, dual-income households, and a serious wellness culture push consistent direct-to-consumer demand at farmers markets in Japantown, Campbell, and the Saturday Downtown San Jose Market. Add the juice bar and smoothie cafe scene built around tech campuses, and direct retail is a real second channel.

Climate is a quiet advantage. Year-round mild weather means heating and cooling costs stay low for indoor racks, and a garage or spare room can run twelve months without seasonal swings. A 5 by 10 foot footprint inside a South Bay home can out-earn most uses of that square footage.

Every week you wait, another Santana Row or downtown chef signs onto a Bay Area distributor pulling product up from Salinas or Watsonville. What does it cost you when the kitchens you wanted to serve are already on someone else's standing weekly order?

The math, in San Jose prices

San Jose wholesale prices for microgreens sit at the top of the national range given Silicon Valley cost of living and the depth of the chef-driven market. Here is what the unit economics look like at conservative South Bay 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 Jose pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in San Jose 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 Jose 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 is the Santana Row and Willow Glen delivery run, Saturday is the Downtown market, and the system tells you exactly which trays to cut. What changes about how you spend the rest of your week when the income side runs on rails?

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

San Jose microgreen FAQ

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

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