MICROGREEN BUSINESS GUIDE · PORT ST. JOHN, FL

Start a microgreen business in Port St. John, FL.

Most Port St. John residents do not realize how far the fresh produce on local menus travels to reach this part of Brevard County. This is a riverside community on Florida's Space Coast, between Cocoa and Titusville, near Merritt Island and the Indian River. The restaurants and markets nearby want fresh, local ingredients, but specialty microgreens are almost never grown here. A grower with one spare room can fill a gap nobody else around is touching.

Quick Answer

You can start a microgreen business in Port St. John with under $400 in initial equipment and grow it into a $900 to $3,000 per month side income within 90 days. Here is the local demand picture, the unit economics at Port St. John wholesale prices, and the operating system used by working microgreen farms.

When a restaurant in Cocoa wants microgreens cut that same morning, where do you imagine they are sourcing them now, and how fresh are they really by the time they arrive.

What Port St. John buys today

The Cocoa and Space Coast dining scene leans on independent restaurants and chefs who make their own sourcing calls. A grower who walks in with a sample tray of micro radish or sunflower shoots becomes the local supplier those kitchens have been missing, with no broadline distributor sitting in the middle.

Brevard County has busy farmers markets and a strong buy-local crowd, supported by both residents and Space Coast visitors. Selling clamshells direct to shoppers, plus a few standing orders to a specialty grocer or juice bar, turns a small setup into reliable weekly income that holds year-round.

Indoor growing is the practical edge in this climate. Space Coast heat, humidity, and storms make outdoor crops unreliable, but microgreens grow on shelves in a controlled room every month of the year. That lets you promise restaurants steady supply when outdoor growers around the county fall short.

If a kitchen over on Merritt Island or in Cocoa Beach could get living trays delivered the day they order, what would that kind of freshness be worth on a Space Coast menu.

What that looks like in Port St. John square footage

A 10 by 10 foot room with simple shelving in Port St. John holds enough trays to supply several Cocoa-area kitchens and a weekend market booth at the same time.

With the Brevard County heat and summer storms that wreck every outdoor garden around Port St. John, have you considered that an indoor rack simply removes the weather from the equation entirely.

Three things every working microgreen farm in Port St. John 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 Port St. John 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 Port St. John. 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 Port St. John grower starting today is not on their own.

Port St. John microgreen FAQ

How much can I make growing microgreens in Port St. John?
A working microgreen farm in Port St. John produces $3,000 to $8,000 per month within 90 days of starting. The math: 100 trays per week, $20 to $30 net revenue per tray, harvested in a basement, garage, or spare room. The ceiling is set by how many restaurants and farmers market customers you can serve, not by the growing setup.
Is it legal to sell microgreens in FL?
Yes. In most of Florida, microgreens fall under the state's cottage food law for direct-to-consumer retail at farmers markets and to private customers. Restaurant wholesale typically requires a basic food handler permit. Verify with the Florida Department of Agriculture before you sign a wholesale contract.
What microgreens sell best in Port St. John?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Port St. John. Broccoli is the highest-margin variety because of its sulforaphane reputation with health-focused buyers. Specialty varieties like amaranth and shiso command premium pricing from chef-driven restaurants.
How much space do I need to grow microgreens in Port St. John?
A 10 by 10 foot room with two shelving units holds 60 to 80 active trays, which is enough to produce $3,000 to $5,000 per month. A basement, garage corner, spare bedroom, or sunroom all work in Port St. John's climate. Vertical shelving is the fastest path to higher revenue per square foot.

The seed density and watering math is the single biggest predictor of how fast you get there.
Do I need a license to sell microgreens in Port St. John?
For farmers market and direct-to-consumer sales in Port St. John, most growers operate under Florida's cottage food law with no special license. For wholesale to restaurants and grocery stores, you typically need a basic food handler permit, a sales tax permit, and depending on volume, an inspection from your county health department.
