Microgreens vs. Mushrooms: Which Apartment Side Hustle Is Actually Better?

Last updated: 09.06.2026

These are the two great apartment food businesses. Both start small, both sell to the same restaurants and markets, and both come wrapped in the same internet promises of easy money. If you have a spare room and want to grow something you can sell, you will end up choosing between them, or wondering if you should do both.

I have grown both. They look similar from the outside and feel completely different in practice. So here is the honest head-to-head: startup cost, difficulty, space, income, and who each one actually suits. No winner declared up front, because the right answer genuinely depends on you.

Startup cost

Microgreens are cheaper to begin. A bootstrap setup of trays, a shelf, a light, medium, and seeds runs a couple hundred dollars, sometimes less. The full breakdown is in the microgreens startup cost guide, and a complete cheap list is in the starter kit under $300.

Mushrooms cost a bit more to start and are fussier about the environment. You are buying or making substrate, managing humidity and fresh air, and often need a small tent or dedicated space. The gourmet mushroom business startup guide covers the real numbers.

Edge: microgreens, by a clear margin, for lowest barrier to entry.

Difficulty and learning curve

Microgreens are forgiving. Sow, blackout, light, water from below, harvest in 1 to 2 weeks. If a tray fails you have lost a week and a few dollars, and you try again. The fastest-growing microgreens give you quick feedback loops to learn from.

Mushrooms are less forgiving and more technical. Contamination is the constant enemy. Mold and bacteria love the same warm, humid conditions mushrooms need, so cleanliness and sterile technique matter a lot. When a mushroom block gets contaminated, you often lose the whole thing. The payoff is that experienced growers get very consistent, but the early learning curve is steeper.

Edge: microgreens for beginners. Mushrooms reward people who like precision and process.

Space and setup

Microgreens grow flat under lights on shelves. You go vertical with a rack and can fit a lot of trays in a small footprint. They need good light but tolerate normal room conditions otherwise, so a spare corner of a Brooklyn apartment or a Berlin Altbau works fine.

Mushrooms need controlled humidity and fresh air exchange, which usually means a tent, a humidifier, and some airflow management. They do not need light the way greens do, so a basement or closet can work, but the environment has to be just right.

Edge: roughly even. Microgreens are simpler; mushrooms can use spaces (dark basements) that greens cannot.

Income and margins

Both can be genuinely profitable, and both sell at premium prices to the same buyers.

Microgreens turn over fast, 1 to 2 weeks per crop, so cash cycles quickly. The honest income ranges are in how much money you can make growing microgreens, and choosing the most profitable varieties drives the margin.

Mushrooms often command higher per-pound prices, especially specialty varieties like lion’s mane, and a single substrate block can fruit multiple times. But the cycle is longer and contamination losses cut into margin.

Edge: even. Microgreens win on speed and predictability; mushrooms win on per-pound price and the wow factor of specialty types.

Who buys them

Good news: the same customers. Independent restaurants, farmers market shoppers, and local food buyers want both. This is the key insight that makes the “versus” a little artificial. The sales skills transfer completely, so whether you pitch restaurants or work a farmers market, the playbook is the same for either crop.

So which should you pick?

Choose microgreens if you want the lowest cost, the fastest learning curve, quick cash cycles, and the simplest setup. It is the better first business for almost everyone, which is why most people start here. The full roadmap is the how to start a microgreens business guide.

Choose mushrooms if you enjoy process and precision, want higher per-pound prices, have a dark space like a basement that suits them, and do not mind a steeper start. Specialty mushrooms also face less competition in many local markets.

Or do both, which is what a lot of established growers end up doing. Here is the real strategy: start with microgreens to learn the selling side and build customer relationships, then add mushrooms (or edible flowers) as a second line to the same restaurants on the same delivery routes. “Fresh microgreens and gourmet mushrooms” is a stronger pitch than either alone, and you spread your risk across two crops.

My honest take: begin with microgreens. Lower cost, faster feedback, easier wins while you are learning the part that actually makes money, which is sales. Add mushrooms once you have buyers who already trust you. That sequence turns the “versus” into an “and,” and that is usually the most profitable answer of all.
