MICROGREEN BUSINESS GUIDE · WESTMINSTER, CO

Start a microgreen business in Westminster, CO.

Most Westminster residents do not realize how the local restaurant base has grown across the US-36 tech corridor and the broader northern Denver metro. The chef-driven kitchens, hotel restaurants, and brunch spots across Westminster and into neighboring Broomfield and Thornton all keep microgreens on the line, and almost all of it ships in from regional distributors. The Westminster grower who plants close to those kitchens has a wide-open market.

Quick Answer

You can start a microgreen business in Westminster with under $400 in initial equipment and grow it into a $2,000 to $5,500 per month side income within 90 days. Here is the local demand picture, the unit economics at northern Denver metro wholesale prices, and the operating system used by working microgreen farms.

If you walked into five chef-driven restaurants between Westminster and Broomfield on a Tuesday and asked where their microgreens were cut, how many do you think would actually name a grower inside the northern metro?

What Westminster buys today

Westminster sits along the US-36 tech corridor between Denver and Boulder, with a customer base that skews higher-income and health-conscious thanks to the heavy presence of tech, biotech, and aerospace employers. The chef-driven restaurant scene across Westminster, Broomfield, and into northern Arvada all keep microgreens on the line, and the spillover demand from Boulder pulls up the wholesale price floor.

The Westminster Farmers Market and the surrounding northern metro market network give you a direct-to-consumer channel during the warmer months. The wellness, juice bar, and prepared-food retail scene along the US-36 corridor adds steady wholesale flow year-round, and the corporate campus dining operations across the tech employers create unusually large single accounts.

For indoor growing, the Front Range climate is genuinely friendly. Dry air that is forgiving for germination control, mild summers at altitude, and a 5 by 10 foot footprint in a Westminster basement or insulated garage can outproduce most side businesses on a weekly basis. Winter heating is included in rent, and the dry climate keeps mold pressure low.

Every week another Westminster or Broomfield kitchen signs a standing order with a Denver-based distributor. What does it cost you when the chefs in the most lucrative US-36 corridor buyer pool are already on someone else's invoice for the next year?

The math, in Westminster prices

Westminster restaurant wholesale prices for microgreens sit in the mid range nationally given the Denver metro cost base and the Boulder-influenced wholesale floor. Here is what the unit economics look like at conservative US-36 corridor 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 Westminster pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

What that looks like in Westminster 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 Westminster 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 and Friday are restaurant deliveries across Westminster and Broomfield, Saturday is the local market, and the system on your phone tells you exactly which trays to cut. What changes about the rest of your week when the income side runs on rails?

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

Westminster microgreen FAQ

How much can I make growing microgreens in Westminster?
A working microgreen farm in Westminster 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 CO?
Yes. In most of Colorado, 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 Colorado Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in Westminster?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Westminster. 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 Westminster?
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 Westminster's climate. Vertical shelving is the fastest path to higher revenue per square foot.

Most growers in Westminster 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 Westminster?
For farmers market and direct-to-consumer sales in Westminster, most growers operate under Colorado'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 Westminster?
Restaurant wholesale in Westminster 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.
