MICROGREEN BUSINESS GUIDE · HIGHLAND, CA

Start a microgreen business in Highland, CA.

Most Highland residents do not realize how shallow the local microgreen supply is at the foot of the San Bernardino Mountains. The restaurants along Base Line and around the casino district are mostly buying microgreens trucked from far outside the region, days after harvest. The Highland grower who fixes that with cut-to-order trays pays themselves first.

Quick Answer

You can start a microgreen business in Highland 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 the working microgreen farms.

Walk into the independent kitchens along Base Line in Highland and ask how often their microgreens are more than five days old by the time they reach the plate. What do you think the honest answer would be?

What Highland buys today

Highland sits at the base of the foothills with quick access to San Bernardino, Redlands, and the resort traffic heading to Big Bear. The local dining mix includes family restaurants, brunch spots, and the casino-adjacent kitchens that serve a steady year round customer flow, all of which are realistic accounts for a local microgreen grower.

The community has a strong farmers market and CSA culture spilling over from neighboring Redlands and the citrus belt, and demographics tilt toward middle income households that increasingly cook health-conscious at home. Direct-to-consumer sales at weekly markets across the east valley round out the wholesale base.

Climate works in your favor. The foothill location runs slightly cooler than the valley floor in summer, and the dry air keeps germination consistent. A spare bedroom or insulated garage with basic climate control holds the temperature window microgreens need without crushing your power bill.

Every week you delay, another fifty trays of weekly demand is being filled by someone shipping in from outside the region. What does walking away from that revenue look like a year from now?

The math, in Highland prices

Here is what the numbers look like for a Highland grower at Inland Empire mid-tier wholesale prices.

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 Highland pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture the week where Sunday is planting, Tuesday and Friday are deliveries through Highland and east San Bernardino, Saturday is the market, and the app tells you exactly what to cut. What changes in your bank account when the route is dialed in?

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

Highland microgreen FAQ

How much can I make growing microgreens in Highland?
A working microgreen farm in Highland 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 Highland?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Highland. 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 Highland?
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 Highland's climate. Vertical shelving is the fastest path to higher revenue per square foot.
What is the best app for tracking microgreen production in Highland?
Grown Like A Pro is the operating system used by working microgreen farms in Highland. It handles seed density math, watering schedules, harvest timing, inventory, customer orders, and the financial side. Free 30-day trial with no credit card.
How long does it take to learn to grow microgreens commercially?
Most growers in Highland 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 Highland?
For farmers market and direct-to-consumer sales in Highland, 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 Highland?
Restaurant wholesale in Highland 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 Highland restaurants currently buy.
