MICROGREEN BUSINESS GUIDE · HERCULES, CA

Start a microgreen business in Hercules, CA.

Most Hercules residents never think about where their fresh greens come from. The kitchens here serving microgreens are almost all supplied by distributors trucking product in along the I-80 corridor, cut long before it arrives. The Hercules grower who delivers trays harvested that same morning owns a position no one local is filling.

Quick Answer

You can start a microgreen business in Hercules 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, and the operating system used by working microgreen farms.

If you asked the restaurants around Hercules and the San Pablo Bay shoreline where their microgreens come from, how many could name a grower from right here instead of a delivery truck?

What Hercules buys today

Hercules sits on the San Pablo Bay shoreline in West Contra Costa, a diverse, higher-income bedroom community where commuters want quality food close to home. That demand has grown faster than the local supply chain, leaving an opening for product that is genuinely fresh and local.

The city sits directly on the I-80 corridor between Richmond and the Carquinez Strait, putting the restaurants of Pinole, Rodeo, and El Cerrito within a short drive of one Hercules grow space. A single delivery loop can cover several towns at once.

The bay-moderated climate stays mild and stable through most of the year, so a small indoor or garage grow room holds steady germination temperatures with minimal heating or cooling. That keeps your power bill predictable and your yields consistent year round.

If a grower along the I-80 corridor locks in the Hercules and Pinole kitchens before you start, what does that closed door cost you across two years of standing orders?

The math, in Hercules prices

Here is what the numbers look like for a Hercules grower selling at a West Contra Costa price tier.

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 Hercules pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Imagine the version of your week where the kitchens from Hercules to El Cerrito all run on your trays, and the app tells you exactly which crops are ready to cut. What would that steady route change about how you spend your time?

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

Hercules microgreen FAQ

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

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