Let me ask you something before we touch a single number. When a YouTube video promises you ten thousand dollars a month from a spare bedroom, what is the one thing it never shows you?
The failed trays. The unsold clamshells. The market that rained out. The chef who stopped answering.
Here is the honest answer, and it is wider than the gurus admit. Selling microgreens can be a few hundred dollars of side income, a real part-time wage, or a full operation that supports a household. All three are true at the same time. The difference is not luck. It is which channels you sell through, how consistent your trays are, and how honestly you count your costs.
It hands you the actual math. Per tray. Per week. Revenue versus take-home. We will use conservative numbers and round ranges, so when your real trays come in, you are pleasantly surprised instead of quietly crushed.
Everything in this business starts with one 10x20 tray. Get this number right and every bigger number is just multiplication.
Your direct cost per tray is seed plus growing medium. Across most popular varieties, that lands in a tight, predictable range.
| Per 10x20 Tray | Conservative Range |
|---|---|
| Seed | $1.50 to $4.00 |
| Growing medium | $0.75 to $1.50 |
| Direct cost total | about $2.50 to $5.50 |
| Harvest weight | 6 to 10 oz |
Now the other side. A typical tray gives you 6 to 10 ounces of cut greens. What that is worth depends entirely on who buys it.
| Sold At | Price / oz | Gross per Tray (8 oz) |
|---|---|---|
| Retail (farmers market) | $3.00 to $4.00 | $24 to $32 |
| Wholesale (restaurant) | $1.50 to $2.50 | $12 to $20 |
| Wholesale (grocery) | $1.25 to $2.00 | $10 to $16 |
One tray is a fact. Income comes from a rotation: a set number of trays finishing every single week, week after week.
Most varieties run a 7 to 14 day cycle. So if you start, say, 10 trays a week on a staggered schedule, you also harvest roughly 10 trays a week once the rotation is full. That steady output is your run rate.
Here is weekly gross at a few honest run rates, using a blended $18 per tray (a realistic mix of retail and wholesale, not best-case retail).
| Trays / Week | Weekly Gross | Monthly Gross |
|---|---|---|
| 10 trays | about $180 | about $720 |
| 25 trays | about $450 | about $1,800 |
| 50 trays | about $900 | about $3,600 |
| 100 trays | about $1,800 | about $7,200 |
So before you fall in love with the 100 tray row, ask the harder question: can you reliably sell 100 trays every week? That sales ceiling, not your grow space, is what caps most operations.
This is the page the hype videos refuse to show you, and it is the most important one in the guide.
Revenue is what lands in the till. Take-home is what is left after the business takes its cut. Between those two numbers sits a list of quiet expenses that beginners forget every time.
Stack those up and a healthy small operation keeps roughly 35 to 55 percent of gross as actual take-home once your own time is paid. So that $3,600 monthly gross at 50 trays a week is closer to $1,300 to $2,000 in your pocket.
You do not really sell microgreens. You sell through a channel, and the channel decides almost everything: your price, your effort, and how steady your income is.
The highest price per ounce and instant cash. The catch is your time. You grow it, you pack it, you stand there all Saturday, and weather or foot traffic can flatten a whole day. High price, high effort, lumpy income.
Lower price per ounce, but a standing weekly order from a chef who actually plans around you. Less time per dollar, far steadier. One good restaurant account is worth a dozen so-so market days.
The lowest price per ounce and the tightest margins, but the largest, most predictable volume. This is how full operations scale, once they can grow consistently enough to never miss a delivery.
Here are the three channels side by side, with conservative price points and the honest trade-off behind each one. Pin this page up.
| Channel | Price / oz | Volume | Steadiness |
|---|---|---|---|
| Farmers market retail | $3.00 to $4.00 | Low to medium | Lumpy |
| Restaurant wholesale | $1.50 to $2.50 | Medium | Steady |
| Grocery wholesale | $1.25 to $2.00 | High | Very steady |
Some growers also sell a clamshell unit instead of by the ounce. A retail clamshell often runs $5 to $7 for a few ounces, which pencils out close to the retail per ounce range above.
Look down the price column and the steadiness column together. The price you give up moving from retail to wholesale, you buy back in predictability and saved time. That is not a worse deal. For most growers, it is the deal that pays the rent.
So what does this actually pay? It depends on which of three operations you are running. Find yourself honestly on this page.
About 5 to 15 trays a week, one market or one or two restaurant accounts. Roughly $200 to $600 a month gross, with take-home in the low hundreds. A real grocery run, beer money plus, on a few hours a week. A genuinely great place to start.
About 25 to 50 trays a week across a blended mix of channels. Roughly $1,500 to $3,600 a month gross, with $600 to $2,000 take-home. This is a meaningful second income that respects your weekends.
100 plus trays a week, multiple grocery and restaurant accounts, possibly an employee. Gross can clear $7,000 a month and up, but so do the costs, the failed trays, and the hours. This is a real business, not a side hustle, and it is earned in that order.
Here is the gap that quietly ends most microgreen businesses. It is not a grow problem. It is a counting problem.
The new grower projects best-case retail price, zero failed trays, and every single tray sold. The real grower lives with a blended price, a handful of dumped trays, and some greens that never found a buyer.
| 50 Trays / Week | Projection | Reality |
|---|---|---|
| Price per tray | $28 retail | $18 blended |
| Trays sold | 50 of 50 | about 42 of 50 |
| Monthly gross | about $5,600 | about $3,000 |
| Monthly take-home | imagined $5,600 | about $1,300 to $1,800 |
That is not a small miss. The projection is roughly three to four times the reality. A grower who budgeted on the left column panics. A grower who planned on the right column is doing exactly fine.
You cannot change the price the market pays by much. So stop pulling on that. Pull on the three levers you actually control, because each one quietly closes the gap from the last page.
A tray that fails costs you twice. You eat the seed and medium, and you lose the sale you promised. Cut your failure rate from 1 in 5 trays to 1 in 20 and you have given yourself a raise without selling a single extra clamshell.
A standing weekly order is the most valuable thing in this business. It turns guesswork into a number you can plan a rotation around. Two or three reliable accounts will steady your income more than any new variety ever will.
Spoilage and unsold stock are pure loss. Selling the same amount with less waste drops straight to take-home. Tighter harvest timing and selling closer to demand fix most of it.
Let me leave you with the uncomfortable truth. The growers who make real money are almost never the best growers. They are the best at knowing their numbers.
They know their true cost per tray. They know their failure rate by variety. They know which account pays on time and which tray spoiled last week. Everyone else is guessing, and guessing is what makes the projection on page 10 feel real until the bank balance argues back.
This is exactly the gap Grown Like A Pro was built to close. It is the operations layer for the math in this guide.
You now know the honest math of selling microgreens. Knowing the numbers and running the numbers are two different things, and the running is where the money actually shows up.
