Microgreen Subscriptions: Not One Crop Here Survives a Monthly Box

A subscription is a promise about time, and this is the one question in the category that can be answered from data rather than from opinion.

The cadence question, settled from the field

This directory publishes a shelf life for 38 of its 62 crops. Read straight off the shelfLifeDays field on every entry rather than from prose about it, and the published figures run from 1 day at the bottom to 21 at the top, which matches the range this site already states.

So ask each cadence whether the crop can actually reach the next delivery.

Not one crop in this directory reaches 30 days, even taken at the most generous end of its own published range. One operator publishes a monthly subscription option. On the evidence this site holds, a monthly fresh-cut box cannot deliver a crop that is still good when the next one arrives, and that is not a close call.

Every other week is a four-crop cadence. Only buckwheat at 21 days, broccoli and mustard at up to 14, and popcorn shoots at up to 14 reach it at their best. Taken at the worst end of their ranges, only buckwheat does.

And weekly is not automatic either. It works for 32 of the 38 at their best figure, but for only 15 of 38 at their worst. So for more than half this directory, a weekly box depends on the crop landing at the good end of its own published range.

The shortest are the ones to watch. Garden cress at 2 to 3 days, turnip at 3, chia at 3 to 5. A crop with a 3 day life cannot be sold on any interval longer than a few days, whatever the plan says.

Twenty-four of the 62 crops here have no published shelf life at all, so for those the question cannot be answered from this directory either way. That is a gap in the field, not permission to assume.

The practical rule. Weekly is the only broadly defensible cadence, biweekly is a short list, and monthly is not a fresh-cut product. If you want a longer interval, a living tray changes the question, because the customer harvests over days rather than storing cut greens.

The discount is wholesale, and you are also the driver

Four operators publish both a subscription price and a one-time price for the same thing, so the discount can be computed rather than asserted.

Now set that beside what the same discounts buy in other channels. The wholesale guide found one seller's published ladder: a chef account gets 20 percent off and a distributor gets 33 percent off.

So the top of the subscriber discount range is exactly the distributor rate, and most of the range sits at or above what a chef pays. The difference is that the distributor collects its own product and the subscriber does not. On a home subscription the grower gives away a wholesale margin and then drives the box to the door.

That is not an argument against subscriptions. It is the reason the delivery has to be costed separately and explicitly, which the next section is about. A discount that would be reasonable at a loading dock is a different proposition at a doorstep.

Delivery is charged inconsistently across the same small sample. One operator charges where applicable, one sets a $50 delivery minimum with free delivery over $99, one gives free delivery over $26, and two fold delivery into the price with no separate line. Record the product revenue and the delivery separately whatever the customer sees, or the route disappears into the price and stops being measurable.

What the route costs, which nobody has published

Zero of six pages advising on starting or scaling a microgreens business publish a route cost figure. The same six: zero publish a retention or churn figure. One of the six publishes a subscription box cost claim, at $5 to produce and $20 to sell.

That $5 is worth checking against this site's own numbers, because it nearly works. Labor is $2.21 to $5.00 a tray and the median seed across the 50 costed crops here is $1.09, so labor and seed alone are $3.30 to $6.09. The $5 claim sits inside that band, which means it has room for nothing else: no medium, no electricity or water, no packaging, and above all no delivery.

The nearest real transport evidence is adjacent and much larger in scale. A 2015 Cornell produce procurement report has retailers and grocery wholesalers estimating transportation at over 26 percent of cost of goods sold, and produce wholesalers at over 19 percent, explicitly excluding local transport from a distribution center to stores. That cannot price a car route around a suburb. What it does establish is that transport is a material line rather than a rounding error, in an industry with far better route density than a home delivery round has.

Route density is the variable, and no operator publishes it. The defined delivery areas are published as places rather than distances: one county, three named towns, a set of metro ZIP codes, a city with pickup and delivery thresholds. Two growers with identical subscriber counts can be opposite businesses if one covers three adjacent streets and the other covers a metro area. Nobody has published stops per hour, miles per stop, or contribution after delivery by density band.

Churn, and why nobody can quote you a number

There is no published microgreen subscriber tenure, cohort retention curve, cancellation rate or median months subscribed. None was found anywhere.

The nearest evidence is community supported agriculture, and it is a warning rather than a forecast.

These are multi-produce shares, usually seasonal and often collected rather than delivered, so none of them is a microgreen box. What they establish is that recurring food revenue churns substantially, with published averages between 46 and 76 percent year to year and individual farms as low as 20 to 25 percent.

Against that, read the operator policies. Skips and pauses are published plainly: cancel, pause or skip before Sunday for a Thursday delivery at one; unlimited skips and pauses with a Wednesday noon cutoff at another; pause, skip and cancel with orders processing two days ahead at a third. Cancel anytime always has an order cutoff attached, because the crop was sown weeks earlier.

So the repeated claim that a subscription is guaranteed or passive income has nothing behind it. What the operators actually support is a narrower and genuinely useful claim: a standing order is a planning input. Several say plainly that it lets them plant to a known demand and waste less. That is true and it is not the same as revenue certainty.

The lead time is a crop fact, not a subscription setting

The first delivery cannot come sooner than the crop grows. One subscription software package enforces this directly, refusing an order whose grow time does not fit the delivery date, with a worked example of basil at 24 days against a delivery 11 days away. One operator asks for two weeks on grow-to-order trays.

So the lead time is per crop and it must include germination, growing, harvest, packing and the route day. The days-to-harvest field here is the place to take it from, and it is not one subscription number.

This is where a customer-choice box becomes expensive. Fixed boxes, rotating boxes and customer-selected boxes are all published practice. A fixed or rotating box is a sowing plan; a box the customer changes between deliveries is a forecast. Both are legitimate and they are not the same operation.

Handover and cold chain

FDA's cut leafy greens guidance calls for 41F, 5C or below during storage and display, with routine temperature monitoring, and says time out of temperature control may only be used under written procedures. That guidance names leafy greens including kale, arugula and chard rather than microgreens as a category, so it is relevant guidance rather than a microgreen door-drop rule. USDA's general delivered-food advice is that cold food should be held at 40F or below and refrigerated promptly, within two hours, or one hour above 90F.

The published handover choices are broader than a doorstep: a front porch, a back door, a restaurant receiving area, a building lobby, meeting apartment customers at the entrance, farm pickup, or hand delivery by the driver. One operator's dated 2020 plan recommends the customer leave a cooler with an ice pack at the door.

A cooler, an ice pack, a delivery notification, a short window and a no-drop rule in extreme heat are sensible controls. Their effectiveness for microgreens specifically has not been validated by anyone.

Cold shipping by carrier is the biggest hole. No operator page documented a shipping tariff, carrier service, package weight, transit time and delivered temperature together. If you are considering shipping rather than driving, that whole cost is unknown and you will have to establish it yourself with dated invoices and a temperature logger.

What to actually do

• Set the cadence from the crop's shelf life, not from what sounds convenient. Weekly is the only broadly defensible interval and it still depends on the crop.
• Do not sell a monthly fresh-cut box. Not one crop here reaches 30 days at its best published figure.
• Check every crop you plan to include against its own shelf life, and drop the 2 to 3 day crops from any subscription or move them to a living tray.
• Compute your subscriber discount and compare it to your wholesale price. If you are giving 33 percent to someone you also drive to, say so deliberately.
• Record delivery separately from product revenue, whatever the customer's invoice shows.
• Cost the route in stops, miles and paid hours before adding subscribers, because density decides this business and subscriber count does not.
• Work the first delivery date backwards from the crop's grow time, including packing and the route day.
• Pick your box model deliberately. A fixed or rotating box is a sowing plan; a customer-changed box is a forecast, and it costs more to run.
• Publish your own cutoff for skips and pauses, because the crop is sown before the customer decides.
• Do not describe it as guaranteed income. Adjacent CSA retention runs from 20 to 95 percent and no microgreen figure exists at all.
• Treat every figure on this page as a snapshot with a place and a date attached. Prices and policies move faster than anything else on this site.

What nobody has measured

• Microgreen subscriber churn. No tenure, cohort curve, cancellation rate or median months subscribed exists anywhere.
• A route cost per stop, in miles, paid driver hours, vehicle and cold-holding cost, for any microgreen subscription.
• Contribution by route density band, which is the number that would actually decide whether this channel works.
• Crop-by-crop eating window after delivery, under a real operator's packaging and temperature.
• The cost of shipping microgreens cold by carrier, with service level, packed weight, zone and delivered temperature.
• What happens after a crop failure, from any written policy and incident log tying notice time to subsequent cancellation.
• Whether a subscription discount is profitable, as opposed to advertised.
• Whether pauses and skips predict cancellation, from any operator's data.
