MICROGREEN BUSINESS GUIDE · TARA HILLS, CA

Start a microgreen business in Tara Hills, CA.

Most people in Tara Hills never think about where the local kitchens get their fresh greens. The restaurants near this West County community serving microgreens are supplied almost entirely by distributors trucking product in along I-80, cut days before. The Tara Hills grower who delivers trays harvested that morning steps into a lane nobody local has claimed.

Quick Answer

You can start a microgreen business in Tara Hills 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, and the operating system used by working microgreen farms.

If you asked the kitchens around neighboring Pinole and Hercules where their fresh garnish comes from, how many could name a grower from right here instead of a delivery truck?

What Tara Hills buys today

Tara Hills is a residential community in West Contra Costa wedged between Pinole and San Pablo, just off the I-80 corridor. The surrounding towns are full of owner-run kitchens whose operators make their own buying calls, so a local grower can talk straight to the person who signs the check.

The location is the advantage. From Tara Hills a grower is minutes from the restaurants of Pinole, Hercules, San Pablo, and Richmond, putting a dense West County base within reach of one grow space. A single delivery loop can cover the entire shoreline cluster.

The bay-moderated climate stays mild and stable nearly all year, so a small indoor or garage grow room holds steady germination temperatures with minimal heating or cooling. That keeps your power bill predictable and your yields consistent across every season.

Every month you wait, another distributor renews its grip on the kitchens around West County. What does it cost you when the owners you wanted to supply are already on someone else's invoice?

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

Imagine the version of your week where the kitchens from Pinole through Richmond all run on your trays, and a system tells you exactly what to seed and cut. What would that steady route change about your month?

Three things every working microgreen farm in Tara Hills 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 Tara Hills 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 Tara Hills. 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 Tara Hills 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 Tara Hills farm on. The growing happens in your basement.

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 CA?
Yes. In most of California, microgreens fall under the state's cottage food law for direct-to-consumer retail at farmers markets and to private customers.

What microgreens sell best in Tara Hills?
Sunflower, pea shoots, and radish are the three highest-volume sellers in nearly every U.S. city, including Tara Hills.
