What Graduate Hospital buys today

Graduate Hospital, the neighborhood just south of Rittenhouse and Center City, has been one of Philadelphia's fastest-growing and most rapidly upscaling areas over the past decade. Young professionals and families have poured in, and with them a steady wave of brunch spots, wine bars, and new chef-driven restaurants that build their menus around fresh, photogenic ingredients.

Most Graduate Hospital kitchens serving microgreens are split between out-of-town distributors and a handful of local growers stretched thin. At least half are settling for sub-par quality because professional-grade local supply is still scarce. Nearly every U.S. city has microgreen farms, and Philadelphia has the demand to support several more.

The demographic here skews higher-income, health-aware, and willing to pay for quality, the textbook microgreen customer. A rowhouse basement or spare room holds the 65 to 75 degree window microgreens want through every Philadelphia season.

If another grower locks in the Graduate Hospital restaurants over the next 90 days, what does that cost you in walked-away revenue across the next two years in one of the city's fastest-growing markets?

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