MICROGREEN BUSINESS GUIDE · OLD MILL BASIN, NY

Start a microgreen business in Old Mill Basin, NY.

Most Old Mill Basin kitchens serving microgreens are split between out-of-town distributors and a handful of Brooklyn-based growers stretched thin. The family-owned dinner rooms and the restaurants around the Kings Plaza corridor plate with greens cut days before they reach the kitchen. The grower in Old Mill Basin who fixes that gets paid first.

Here is the local demand picture, the unit economics at Old Mill Basin wholesale prices, and the operating system used by working microgreen farms.

How often do you walk into a restaurant around Kings Plaza and hear that the microgreens on the plate were grown by someone in Brooklyn?

What Old Mill Basin buys today

Old Mill Basin is a quiet, residential pocket of southeast Brooklyn sitting between Mill Basin, Marine Park, and Flatlands. The restaurant economy on its own is small, but the neighborhood sits inside a much larger southeast Brooklyn dining footprint that includes Kings Plaza, Avenue U, and Flatbush Avenue.

A single grower based in Old Mill Basin can dispatch deliveries to dozens of family-owned dinner rooms, pizza counters, seafood spots, bakeries, and cafes within a fifteen minute drive. At least half of those kitchens are settling for sub-par microgreens today because professional-grade local supply is still scarce. Nearly every U.S. city has microgreen farms. Brooklyn has the demand to support several more.

For indoor growing, the detached and semi-detached homes in Old Mill Basin typically have finished basements, garages, and dedicated utility rooms that hold the 65 to 75 degree window microgreens want with normal heat and a window unit in summer. The home base footprint is among the largest you can secure anywhere in Brooklyn.

Every month you wait, another Kings Plaza area kitchen signs a default contract with a national distributor. What is the cost of letting the closest restaurants to your front door buy from a truck instead of from you?

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

Picture the version of your week where Sunday is planting day, Tuesday is restaurant delivery across Mill Basin and the Kings Plaza corridor, Saturday is direct-to-consumer pickup, and the app tells you exactly which trays to cut. What changes about how you spend the rest of your week?

Three things every working microgreen farm in Old Mill Basin 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 Old Mill Basin 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 Old Mill Basin. 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 Old Mill Basin 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 Old Mill Basin farm on. The growing happens in your basement.
