Microgreens As A Business

Setting Up a Microgreens Operation Without Wasting Your Money

The first thing you need to figure out is whether you actually want to do this long-term. A lot of people read about microgreens being easy money and sign up for tray supply without thinking through the daily reality. You grow something, harvest it, wash it, package it, deliver it, then do it again tomorrow. It is not complicated but it is repetitive in a way that makes most beginners quit within six months. I learned that after burning through about four thousand dollars in my first year on equipment I barely used. You are really running two businesses at once. One is production. The other is sales. The production side is straightforward once you get past the learning curve, which usually takes about eight to twelve weeks depending on what varieties you start with. You will lose trays to mold, some batches will bolt, and you will mess up watering schedules more than you want to admit. The sales side is where most people fall apart because growing well does not mean anyone will buy from you. I run a small production setup doing about sixty to eighty trays per week across ten varieties. My space is a converted garage with a ceiling fan, a grow light array on a timer, and a rolling table system. I started with a single shelf unit and twenty trays. That produced roughly four hundred grams per harvest cycle, which translates to maybe two hundred dollars in wholesale revenue if I am lucky. The math did not look promising at that scale. What changed things was shifting to chef accounts instead of farmers markets. Farmers markets kill your margins on time alone.

One specific problem that caught me off guard was thistles and sunflowers. These two varieties are high-margin staples that almost every vendor grows, but they have a germination issue that is not covered in any of the beginner guides. When you stack trays densely, which you have to do to make the economics work, the humidity between the trays gets too high during the first forty-eight hours. Thistle seeds will go dark and slimy if you do not vent them properly during the domed stage. Sunflower seeds develop a crust on the soil surface that prevents emergence if you water from above during germination. The workaround is simple but it is not obvious. I use a spray bottle for the first watering, not a gentle shower head. Then after the initial twenty-four hour dome period, I remove the dome and switch to overhead watering with a fine mist nozzle. I also space the trays apart slightly rather than nesting them tight during that first critical phase. It costs you a little space but it prevents what would otherwise be a two-hundred tray loss in a single batch. I had a whole batch of magenta sunflower go bad in week two and had to throw it out. That was a four hundred dollar loss on seed alone and the wasted growing media on top of it.

Equipment and Setup Costs

You do not need expensive equipment. The core list is shallow propagation trays with lids, a quality growing medium, grow lights, a watering source, and something to weigh and package with. Shallow trays are non-negotiable. Standard seed starter trays are too deep and they hold too much water, which is how you get root rot and fungus gnats. Six by eight inch trays at about two inches deep are the standard size in this industry. They cost roughly sixty to eighty cents each when you buy them in bulk packs of one hundred. Lighting is where people overspend. A single T5 fluorescent fixture or a quality LED panel can cover a four by eight foot table. You do not need full spectrum shop lights with high PAR ratings the way you do for leafy greens or herbs. Microgreens only need about two hundred to four hundred micromoles per square meter per second during the growth cycle. That is very low compared to mature plant operations. A single 4-foot LED bar costing around sixty dollars will handle two full tables comfortably. Spend more on lights than you need and you are just burning electricity for no return. My total startup cost landed around three thousand dollars, and that included buying everything new. Half of that was shelving and trays. About four hundred went toward lights. The rest was medium, seed stock, a digital hygrometer, a harvest scale, and packaging supplies. I have since upgraded to a used commercial refrigerator for holding finished product, which saved me about five hundred dollars compared to buying new. That unit keeps product at thirty-four degrees and extends shelf life to seven to ten days depending on the variety.

Growing Medium and Seed Sourcing

The medium you use matters more than most people think. Coconut coir is the standard, but not all coir is equal. Cheap coir from bulk suppliers often has high salt content and will stunt your growth or kill trays outright. I test a batch by soaking a handful in distilled water and checking the electrical conductivity with a cheap TDS meter. Anything above three hundred parts per million is too salty for microgreen production. Good coir should read under one hundred fifty TDS. Seed sourcing is another area where mistakes are expensive. Do not buy grocery store seeds intended for consumption. Those are untreated but they are also not graded for germination rates. You need agricultural-grade seed that has been tested for germination, which means the supplier should be able to provide a germination rate of ninety percent or above. I order from specialty agricultural seed companies that cater to microgreen growers. The price per pound is higher than grocery store seeds but the germination rate is significantly better, which means less waste and fewer crop failures. Here is a practical detail most guides skip: soak hard-seeded varieties like cilantro, dill, and coriander for twelve to twenty-four hours before planting. This cuts germination time by about a third and improves uniformity. Soft-seeded varieties like basil and lettuce do not benefit from soaking and can actually crack or rot if you soak them. That distinction alone saved me from ruining three consecutive batches of basil when I first started out.

Production Workflow

A typical cycle runs seven to fourteen days depending on the variety. Radish goes from seed to harvest in about eight days. Wheatgrass takes fourteen. You seed, dome for two days, water, uncover, grow for five to twelve more days, then harvest and clean. Here is what a realistic weekly production schedule looks like at my operation. Monday and Thursday are seeding days. Tuesday, Wednesday, Friday, and Saturday are harvest days. That gives me a continuous rotation where each tray type follows the same calendar. I plant about ten to twelve trays of each variety per seeding day, which means I am seeding roughly twenty-five to thirty trays twice a week across all varieties combined. The harvesting step takes about twenty minutes per tray when you have the process down. That includes cutting, weighing, portioning into clamshells or bags, labeling, and placing in the refrigerator. I use a sharp serrated knife and cut about a quarter inch above the soil line. The medium stays in the tray and gets composted after each harvest rather than being reused, which eliminates the risk of carrying over pathogens between cycles.

Sales Channels and Pricing

Wholesale pricing typically runs between four and twelve dollars per half-pound clamshell depending on the variety and your local market. Radish and sunflower command the lower end while exotic varieties like amaranth and mizuna can reach eight to twelve dollars. The key to making this work is selling volume, not premium pricing on a few rare varieties. My most reliable accounts are restaurants that use microgreens as a garnish and ingredient on every plate. One counter-intuitive thing about selling to restaurants: consistency matters more than perfection. A chef will keep ordering from you if your product is consistently good even if it is not the absolute best they have ever tasted. They will drop you the moment one shipment comes in with inconsistent stems or uneven color. I once had a chef tell me directly that my radish microgreens were slightly smaller than what his other supplier provided, but he kept ordering from me because I never missed a delivery and the product arrived in the same condition every single time. That relationship has been steady for over two years now. Farmers markets can work but the economics are rough. You are competing with other vendors, you need to set up and break down every weekend, and you are limited to whatever you can sell in a single day. A well-run market stall might net you two hundred to four hundred dollars per event after expenses. The same amount of growing space and labor delivered to restaurant accounts can generate eight hundred to twelve hundred dollars per week with far less physical effort.

Common Pitfalls and Where the Model Breaks Down

The biggest mistake beginners make is overestimating how much they can sell and underestimating how much work the daily routine actually is. I started by committing to supply three restaurants on day one with orders I could not realistically fulfill. That got me dropped from both accounts within a month. It is better to start with one or two accounts and scale up as your production capacity stabilizes. Another pitfall is growing too many varieties too early. Each variety has slightly different timing, watering needs, and pest profiles. I expanded to fifteen varieties within my first four months and spent most of that time firefighting problems with the less common varieties instead of perfecting the ones that were already profitable. I cut my variety count back to eight and my revenue increased by about thirty percent because I stopped wasting trays on slow movers. There are scenarios where microgreens as a business simply will not work for you. If you live in a region where the summer humidity regularly pushes indoor relative humidity above seventy percent without climate control, mold becomes a serious and ongoing problem. I know growers in Florida and Louisiana who deal with this every year and many of them switch to hydroponic mat systems or move their operations to a cooled space with dehumidification. The margin hit from those equipment costs is real and it eliminates the low-overhead advantage that makes microgreens attractive in the first place. If you are in a high-humidity climate, do the math on dehumidifier electricity costs before you commit to soil-based growing.

Another hard limit is transportation. If you do not have a vehicle that can get product to buyers within two hours of harvest, your product quality will degrade and you will lose accounts. Microgreens are a fresh product with no preservatives and they wilt quickly. I live about twenty minutes from my nearest customer cluster and even that drives my delivery schedule tight. If you are rural and your customers are spread out over an hour or more, the economics change significantly.

Numbers That Actually Matter

A single six by eight inch tray with coconut coir holds roughly one cup of growing medium and seeds from about two to three grams of seed, depending on the variety. That tray produces between eighty and one hundred fifty grams of finished microgreens when harvested properly. At wholesale pricing, that is roughly one to four dollars per tray depending on the variety. Your seed cost per tray is usually between five and fifteen cents. Your medium cost is about ten to fifteen cents per tray if you compost it after each use. The real cost is your time. At a comfortable pace, one person can seed, harvest, and package about twenty to thirty trays in a four-hour work session if they have an organized setup. That translates to roughly twenty to forty dollars in wholesale revenue per person-hour at conservative pricing. After accounting for packaging, transportation, and overhead, the net margin is usually in the twenty-five to forty percent range for established operations. New operations in their first year tend to run much lower because of wasted trays and the time spent building accounts. If you are tracking profitability, the metric that matters most is trays per square foot per week. A well-run vertical setup can produce eight to twelve trays per square foot per week depending on your rack configuration and variety mix. Anything below six trays per square foot per week means your space is underutilized. Anything above twelve usually means you are cutting corners on quality or working yourself into burnout.

When to Walk Away

This business model works well as a side income or a small supplemental operation. It does not scale easily into a full-time livelihood unless you either invest significantly in automation and climate control or expand into a distribution model where you manage other growers and take a margin on their product. I know people who have built six-figure microgreen operations but they all ended up functioning more as aggregation and distribution businesses rather than pure grower operations. The hands-on growing part has hard limits on how much income it can generate per person. If you are considering this, start small, validate your sales channels before you buy more than a month of equipment, and keep your variety count low until you have a repeatable process. The product itself is straightforward to grow. The business side is where the actual challenge lies.
