MICROGREEN BUSINESS GUIDE · HIGHGROVE, CA

Start a microgreen business in Highgrove, CA.

Most people pass through Highgrove on their way between Riverside and the 215 without realizing it is its own community sitting right on the seam of three cities. That position, wedged near Riverside, Grand Terrace, and Colton, puts it within minutes of a huge restaurant base that still imports its microgreens. The grower in Highgrove who starts first turns a central location into short routes and steady weekly orders.

Quick Answer

You can start a microgreen business in Highgrove 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, and the operating system used by working microgreen farms.

Sitting this close to Riverside and the San Bernardino line, how many restaurants within ten minutes of you are buying greens that traveled hundreds of miles to get there?

What Highgrove buys today

Highgrove is a small community at the northern edge of the city of Riverside, near the Riverside and San Bernardino county line, with a working-class, family-centered population and a long history tied to the citrus groves and rail lines that built the area.

The real opportunity is its location. From Highgrove a grower sits within a short drive of Riverside, Grand Terrace, Colton, and the broader Inland Empire restaurant corridor, one of the largest combined dining markets between Los Angeles and the desert. That density means a single grow room can supply family kitchens and chef-driven spots across multiple cities without long, fuel-burning routes.

For indoor growing, the inland heat is the main thing to plan for. A garage, shed, or spare room with cooling holds the 65 to 75 degree germination window microgreens want, and the long mild seasons keep your operating costs low the rest of the year.

If your location is the edge nobody else is using, how does it sit with you to watch a grower from a neighboring city claim the Riverside and Colton accounts you could reach faster than they can?

The math, in Highgrove prices

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

What changes for you when your central spot turns into a hub: trays cut in the morning, dropped across Riverside and the county line by lunch, all on routes shorter than your old commute?

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

Highgrove microgreen FAQ

How much can I make growing microgreens in Highgrove?
A working microgreen farm in Highgrove produces $3,000 to $8,000 per month within 90 days of starting.

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 Highgrove?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Highgrove. 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 Highgrove?
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 Highgrove'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 Highgrove?
For farmers market and direct-to-consumer sales in Highgrove, 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.
