MICROGREEN BUSINESS GUIDE · DUBLIN, CA

Start a microgreen business in Dublin, CA.

Most Dublin residents do not realize how little of what gets plated at the new restaurants along Dublin Boulevard was grown anywhere nearby. The Tri-Valley dining scene has expanded fast and the supply chain has not kept up. The Dublin grower who steps in first becomes the local name on a list that currently has no local name on it.

Quick Answer

You can start a microgreen business in Dublin with under $400 in initial equipment and grow it into a $2,800 to $7,000 per month side income within 90 days. Here is the local demand picture, the unit economics at Dublin wholesale prices, and the operating system used by working microgreen farms.

How many of the new restaurants along Dublin Boulevard and out near the BART station right now are serving microgreens that were not actually cut anywhere in the Tri-Valley this week?

What Dublin buys today

Dublin has been one of the fastest-growing cities in the Bay Area for over a decade, with the restaurant scene and new commercial corridors expanding faster than the local food supply chain. The demographic is affluent, dual-income, and skews toward health-aware eating, which is a strong match for premium fresh produce.

The weekend farmers markets in the broader Tri-Valley pull a willing-to-pay buyer base, and the juice bar and wellness culture around the BART corridor and into Stoneridge layers in steady direct-to-consumer demand alongside the restaurant base.

For indoor growing, the climate is forgiving for most of the year. The main consideration is summer heat, which is handled by a window AC in a garage or insulated room. The rest of the year, a small grow space sits inside the productive window with minimal effort.

Every week you wait, another new Dublin Boulevard concept signs a 12-month supply agreement with a distributor outside the valley. What does it cost you when the kitchens you wanted are already on someone else's invoice?

The math, in Dublin prices

Dublin sits in the mid to upper tier of California wholesale pricing, with Tri-Valley accounts paying a meaningful premium for genuinely local cut-to-order product. Here is what the unit economics look like at conservative Dublin 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 Dublin pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Dublin 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 Dublin 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, the BART corridor and Dublin Boulevard kitchens are on standing Tuesday delivery, and you are choosing which one new account to onboard each month. What changes about how you spend the rest of the week?

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

Dublin microgreen FAQ

How much can I make growing microgreens in Dublin?
A working microgreen farm in Dublin 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 Dublin?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Dublin. 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 Dublin?
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 Dublin's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Dublin?
Grown Like A Pro is the operating system used by working microgreen farms in Dublin. It handles seed density math, watering schedules, harvest timing, inventory, customer orders, and the financial side. Free 30-day trial with no credit card.
How long does it take to learn to grow microgreens commercially?
Most growers in Dublin 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 Dublin?
For farmers market and direct-to-consumer sales in Dublin, 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 Dublin?
Restaurant wholesale in Dublin 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 Dublin restaurants currently buy.
