MICROGREEN BUSINESS GUIDE · KENNEWICK, WA

Start a microgreen business in Kennewick, WA.

Most Kennewick residents do not realize that the city is the retail and restaurant hub of the Tri-Cities and yet has no full-time local microgreen supplier serving its kitchens. The chef-driven base along Columbia Center Boulevard and downtown, the wine country tourism overflow, and the steady growth of the local restaurant economy all support a grower who shows up consistently. The Kennewick grower who claims that gap first ends up with no real competition.

Quick Answer

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

Walk into the chef-driven restaurants in downtown Kennewick and along the Columbia Center corridor on a Tuesday and ask where the microgreens come from. How many of those kitchens are buying from a Tri-Cities grower versus a regional truck?

What Kennewick buys today

Kennewick anchors the retail and dining side of the Tri-Cities, which means more restaurant accounts per square mile than its sister cities across the river. The chef-driven downtown rebuild, the Columbia Center Boulevard corridor, and the steady growth of independent restaurants all create accounts that buy microgreens for plating and salads.

The wine country tourism economy carries through Kennewick, and the catering and event business tied to the Three Rivers Convention Center supports recurring weekly volume. Direct-to-consumer demand comes through the regional farmers market scene and a wellness-driven cafe and juice bar cluster that buys microgreens as a recognized product, not a curiosity.

For indoor growing in Kennewick, the summer heat is the main climate consideration. Triple-digit days require a window AC, basement, or insulated shed, but winters are dry and stable and the 65 to 75 degree window holds easily for the rest of the year.

Every quarter you wait, another Kennewick account locks into a distributor agreement that becomes harder to dislodge. What does it cost when the chefs you wanted to pitch are already on someone else's invoice?

The math, in Kennewick prices

Kennewick restaurant wholesale prices for microgreens sit at the Tri-Cities average, with the wine country and chef-driven accounts paying premium for cut-to-order product. Here is what the unit economics look like at conservative Kennewick numbers in the standard $1,800 to $5,000 per month tier.

Startup cost

Trays, soil, seed, lights. Used gear cuts this in half.

Trays per week

Break-even week

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

Imagine the week where Sunday is the planting day, Tuesday is restaurant delivery downtown and along Columbia Center, Saturday is the market, and the app tells you exactly which trays to cut. What changes about your week when the business runs on a system?

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

Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Kennewick.
