MICROGREEN BUSINESS GUIDE · DUMBO, NY

Start a microgreen business in DUMBO, NY.

Most DUMBO residents do not realize how much of the microgreen supply for the waterfront restaurants and corporate cafeterias under the Manhattan Bridge is split between out-of-town distributors and a handful of Brooklyn-based growers stretched thin. At least half the kitchens are settling for sub-par quality because professional-grade local supply is still scarce. The DUMBO grower who steps up first owns one of the highest dollar-per-plate corridors in the borough.

Quick Answer

You can start a microgreen business in DUMBO with under $400 in initial equipment and grow it into a $3,000 to $8,000 per month side income within 90 days. Here is the local demand picture, the unit economics at Brooklyn wholesale prices, and the operating system used by the working microgreen farms.

Walk into five spots along Water and Front Street on a Tuesday and ask the chef where the microgreens were cut. How often is the answer a distributor instead of a grower across the BQE?

What DUMBO buys today

DUMBO packs hotels, tech offices, a major architecture and design crowd, and some of the most photographed restaurant patios in New York into a few cobblestone blocks. The food prices run premium because the rent runs premium, and the kitchens here lose customers if they cut corners on plating. Microgreens are part of the visual standard.

The corporate cafeterias and catering accounts inside DUMBO's tech tenant base also represent a large, steady wholesale buyer that does not get talked about as much as restaurant accounts but writes bigger checks. A local grower with consistent supply can lock in standing orders that one or two distributors are currently coasting on.

For indoor growing, the converted warehouses and pre-war buildings throughout DUMBO and adjacent Vinegar Hill hold the 65 to 75 degree microgreen window well once a small dehumidifier and a window AC are dialed in. Nearly every U.S. city has microgreen farms. Brooklyn has the demand to support several more.

Every week you wait, another forty trays of revenue ride past you on a refrigerated truck from out of state. What happens to your shot at the DUMBO hotel and cafeteria accounts when next year's growers already have the standing orders signed?

The math, in DUMBO prices

DUMBO restaurant wholesale prices for microgreens run at the premium NYC tier, with hotel and chef-owned spots paying top dollar for cut-to-order local product. Here is what the unit economics look like at conservative Brooklyn 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 DUMBO pricing.

Break-even week

Week 4

First positive cash week. Most growers hit it.

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

Picture the week where Sunday is planting day, Tuesday is delivery along Water and Front, Friday is the corporate cafeteria route, and the app tells you exactly which trays to cut. What changes about the rest of your life once the business runs on a real system?

Three things every working microgreen farm in DUMBO 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 DUMBO 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 DUMBO. 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 DUMBO 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 DUMBO 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 DUMBO.
