MICROGREEN BUSINESS GUIDE · COVINA, CA

Start a microgreen business in Covina, CA.

Most Covina residents do not realize how thin the local microgreen bench really is. This is a mid-size San Gabriel Valley city with a walkable historic downtown and a steady dining scene, yet the greens on local plates are mostly shipped in from out of the area. The grower in Covina who fixes that, with truly local trays, is the one who gets paid first.

Quick Answer

You can start a microgreen business in Covina 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 think about the restaurants around downtown Covina and along the main corridors, how many of them are serving microgreens grown anywhere near the city?

What Covina buys today

Covina is a mid-size city in the eastern San Gabriel Valley with a genuinely walkable historic downtown, a rarity in the car-built valley, that hosts independent restaurants, a regular farmers market, and community events. That downtown gives a grower a natural hub of independent kitchens that prize local sourcing.

The city sits among West Covina, Glendora, Azusa, and San Dimas, all populous and food-active, so a grower here can reach a broad spread of wholesale and direct buyers in a short drive. The downtown market and the wider valley network give a direct-to-consumer channel from the start.

The climate is warm inland coastal, with summer heat as the main growing variable. A garage or spare room holds the 65 to 75 degree microgreen window cheaply, keeping power costs predictable and germination consistent through the year.

If a grower in a neighboring valley city locks in the downtown accounts over the next 90 days, what does that walked-away revenue cost you across the next two years?

The math, in Covina prices

Here is what the unit economics look like for a Covina grower at an eastern San Gabriel Valley metro 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 Covina pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture six months from now: a planting day, a delivery loop through downtown and the surrounding towns, and a market booth, all on a schedule the app hands you. How does that change the rest of your week?

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

Covina microgreen FAQ

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

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