MICROGREEN BUSINESS GUIDE · TEMPE, AZ

Start a microgreen business in Tempe, AZ.The app starts at only $3 a month.

Most Tempe growers do not realize the size of the wholesale microgreen gap sitting along Mill Avenue. The Arizona State campus economy pulls one of the densest concentrations of independent restaurants in the Phoenix metro, and most of those kitchens are buying from broadline distributors. The Tempe grower who fixes that gap effectively owns the east valley.

Quick Answer

You can start a microgreen business in Tempe 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 at Tempe wholesale prices, and the operating system used by working microgreen farms.

If you walked into five Mill Avenue or downtown Tempe restaurants on a Tuesday and asked where their microgreens were cut, how many would actually name an east valley grower?

What Tempe buys today

Tempe's restaurant economy is anchored by Arizona State University, with Mill Avenue and the corridor through downtown Tempe and the Town Lake district carrying a density of independent kitchens that few cities of this size match. The food scene leans modern American, Mexican, Korean, and plant-forward, and microgreens fit cleanly across almost every plate style on those menus.

The Tempe Farmers Market on Mill Avenue plus the seasonal markets across the east valley pull a customer base skewed younger, educated, and health-aware, which is the textbook microgreen buyer profile. The juice bar, smoothie cafe, and wellness food scene around campus and the Town Lake district adds a steady retail channel on top of the wholesale base.

For indoor growing, the Sonoran desert climate is a genuine advantage. Low ambient humidity means dramatically less mold pressure on trays than coastal cities deal with, and a garage or spare room with a window AC holds the 65 to 75 degree window even through Phoenix summers. Winters require almost no heat.

Every month you wait, another Mill Avenue or Town Lake restaurant signs a 12-month supply agreement with a distributor truck rolling through. What does it cost you when the kitchens you wanted to sell to are already on someone else's standing invoice?

The math, in Tempe prices

Tempe restaurant wholesale prices for microgreens sit at the Phoenix metro tier, with chef-driven and campus-adjacent accounts paying a real premium for genuinely local cut-to-order product. Here is what the unit economics look like at conservative Tempe 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 Tempe pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Tempe 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 Tempe 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 restaurant delivery along Mill Avenue and Town Lake, Saturday is the Tempe Farmers Market, and the system tells you exactly which trays to cut. What changes about your week when the income side runs on rails?

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

Tempe microgreen FAQ

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

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