MICROGREEN BUSINESS GUIDE · POWAY, CA

Start a microgreen business in Poway, CA.

Most Poway residents do not realize how thin the local supply runs for the restaurants in their own community. The kitchens around the Poway business park and the old town corridor mostly plate greens that were cut elsewhere and trucked in days earlier. The grower in Poway who fixes that, with trays harvested the morning of delivery, pays themselves first.

Quick Answer

You can start a microgreen business in Poway with under $400 in initial equipment and grow it into a $2,500 to $6,500 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.

When you eat out in Poway and a plate arrives with a fresh garnish, how often do you think those greens were harvested within the valley rather than shipped in?

What Poway buys today

Poway calls itself the City in the Country, and it backs that up with a semi-rural character, large lots, and a community that values local agriculture more than most suburbs its size. That cultural openness to growing makes it an unusually friendly market for a home-based microgreen operation.

The city sits in an inland valley, so summer heat is the main consideration for an indoor grow. A garage or spare room with modest cooling holds the temperature window microgreens want, and the dry air keeps mold pressure low across the year.

With an affluent, family-oriented, quality-aware population, a strong weekly farmers market, and a mix of independent restaurants in old town Poway, a new grower has both a premium direct-to-consumer channel and a reachable wholesale base close to home.

If another grower locks in the old town restaurants and the market crowd over the next 90 days, what does that cost you in walked-away revenue over the next two years?

The math, in Poway prices

Here is what the numbers look like for a Poway grower selling at a mid-market San Diego County 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 Poway pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

What would it look like six months from now if the salads and garnishes at the restaurants within a few miles of your house all carried your label, and the market crowd knew your name? In a town this proud of local, that is just consistent delivery on schedule.

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

Poway microgreen FAQ

How much can I make growing microgreens in Poway?
A working microgreen farm in Poway 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 Poway?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Poway. 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 Poway?
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 Poway'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 Poway?
For farmers market and direct-to-consumer sales in Poway, 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.

Restaurant wholesale in Poway 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.
