MICROGREEN BUSINESS GUIDE · SAN LUIS, AZ

Start a microgreen business in San Luis, AZ.

Most San Luis residents do not realize how little of the microgreen product served on local plates is actually grown nearby. The restaurants here run on distributor invoices, not local farms. The San Luis grower who fills that gap pays themselves first.

Quick Answer

You can start a microgreen business in San Luis with under $400 in initial equipment and grow it into a $1,800 to $5,000 per month side income within 90 days. Here is the local demand picture, the unit economics at San Luis wholesale prices, and the operating system used by working microgreen farms.

Walk into five San Luis and south Yuma County restaurants on a Tuesday and ask where they source microgreens. How often is the answer a local grower instead of a distributor?

What San Luis buys today

San Luis sits right on the U.S. Mexico border, with an economy tied to cross-border trade, winter vegetable agriculture, and a steady commercial restaurant scene. The combination of working families, agricultural seasonal workers, and the broader Yuma County metro pulls a microgreen grower into a regional foodservice opportunity, not just a small-town one.

The local market scene runs primarily through the larger Yuma weekend markets and the cross-border trade flow. Demographics skew younger and family-focused, with a strong Spanish-speaking customer base where premium fresh produce is appreciated and chef-grade microgreens are a clear upgrade for the better restaurants.

For indoor growing, San Luis's intense summer heat is the main consideration. A spare bedroom, garage with a dedicated window AC, or insulated shed holds the 65 to 75 degree window microgreens want, and once heat is solved the dry desert air keeps mold pressure low.

Every month you wait, another Yuma County kitchen renews a 12-month delivery agreement with an outside distributor. What does it cost you when the regional accounts you wanted to sell to are already on someone else's invoice?

The math, in San Luis prices

San Luis wholesale prices run at the standard tier, with chef-driven Yuma County accounts paying premium for genuinely local cut-to-order product. Here is what the unit economics look like at conservative San Luis 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 Luis pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Imagine the version of your week where Sunday is planting day, Tuesday is regional restaurant delivery, Saturday is the market, and the app tells you exactly which trays to cut. What would change about your week when the business runs on a system?

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

San Luis microgreen FAQ

How much can I make growing microgreens in San Luis?
A working microgreen farm in San Luis 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 AZ?
Yes. In most of Arizona, 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 Arizona Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in San Luis?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including San Luis. 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 Luis?
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 Luis'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 San Luis?
For farmers market and direct-to-consumer sales in San Luis, most growers operate under Arizona'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.
