MICROGREEN BUSINESS GUIDE · PARK SLOPE, NY

Start a microgreen business in Park Slope, NY.

Most Park Slope kitchens serving microgreens are split between out-of-town distributors and a handful of Brooklyn-based growers stretched thin. The brownstone-row brunch rooms and Fifth Avenue chef spots plate with greens that were cut days ago in another state and trucked in cold. The grower in Park Slope who fixes that, with trays harvested the morning of delivery, gets paid first.

Quick Answer

You can start a microgreen business in Park Slope 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 Park Slope wholesale prices, and the operating system used by working microgreen farms.

Walk into five restaurants on Fifth or Seventh Avenue on a Tuesday and ask the chef where their microgreens come from. How often do you hear the name of a grower who actually lives within walking distance?

What Park Slope buys today

Park Slope sits in the heart of Brooklyn and runs on one of the most concentrated brownstone-block restaurant scenes in New York City. Fifth and Seventh Avenue carry chef-owned bistros, farm-to-table dinner rooms, and brunch destinations where plating standards are high and pickup windows are tight, which is exactly the buyer profile that pays for genuinely local microgreens.

The neighborhood also has one of the most loyal year-round greenmarket cultures in the borough. The Grand Army Plaza market at the corner of Prospect Park anchors a high-income, food-aware demographic that knows the difference between a tray cut yesterday and one shipped in from somewhere else. At least half of the kitchens currently buying greens here are settling for sub-par quality because professional-grade local supply is still scarce.

For indoor growing, a Park Slope brownstone parlor floor, a finished basement, or a back-of-house room in a co-op holds the 65 to 75 degree window microgreens want with almost no fight. Brooklyn has the demand to support several more growers, and the kitchens around Prospect Park are first in line.

Every week another Fifth Avenue chef signs a 12-month contract with a distributor truck rolling in from out of state. What does it cost you when the kitchens you wanted as accounts are already on someone else's invoice next year?

The math, in Park Slope prices

Park Slope sits in a premium Brooklyn pricing tier, with chef-driven and farm-to-table accounts paying at the top of the New York range for genuinely local cut-to-order trays. Here is what the unit economics look like at conservative Park Slope numbers.

What that looks like in Park Slope 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 Park Slope 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 up and down Fifth Avenue on foot or by cargo bike, Saturday is the Grand Army Plaza market, and the app tells you exactly which trays to cut. What changes about the rest of your life when the business runs on a system?

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