Food Crops Grown Under Cover (NAICS 11141) — A U.S. Industry Rollup Primer

A Histometrics primer for public- and private-market investors

North American Industry Classification System (NAICS) code 11141, Food Crops Grown Under Cover, is the federal category for growing food indoors or under protective structures instead of in open fields. It has two child industries: 111411 Mushroom Production and 111419 Other Food Crops Grown Under Cover (greenhouse vegetables, herbs, berries, hydroponics, and enclosed "vertical" farms). Together they form the food-producing core of what the trade calls controlled environment agriculture (CEA). This primer synthesizes the two already-written child primers; its distinctive value is the contrast between them.

1. Overview

The unifying idea of NAICS 11141 is that these crops are grown in a building, not a field — climate-controlled, year-round, and largely independent of weather and season. That makes both children look more like light manufacturing than like row-crop farming: the swing factors are labor, energy, capacity utilization, yield per square foot, food safety, and cold-chain discipline — not acreage or rainfall. Both are capital-heavy, thin-margin, highly perishable businesses in which the gap between what you grow and what you actually sell (shrink, disease, cosmetic rejects, spoilage) is where money is made or lost.

The two children share that operating DNA but sit at opposite ends of the investing spectrum. Mushrooms (111411) are a mature, quietly consolidating industry dominated by large private and private-equity-backed growers, with a small fast-growing specialty/functional layer on top. Greenhouse and indoor food crops (111419) just lived through one of the sharpest boom-and-bust cycles in recent agriculture — a venture-capital bubble in "vertical farming" that burst, leaving a handful of distressed public microcaps and a stronger private core. For a general investor the single most important takeaway is the same for both: there is essentially no clean, blue-chip public pure-play in either child. The real ownership — and the best risk-adjusted entry points — sit in private hands.

2. What's inside — the two child industries and how they differ

Both children are CEA food producers of roughly comparable farm-gate size (each around $1 billion a year), regulated the same way and driven by the same food-safety and local-supply tailwinds. But their maturity, ownership, import exposure, and how you actually invest differ sharply. (Tickers appear only in Sections 4 and 10.)

The one-line contrast: mushrooms are the boring, durable, private half — a resilient food staple that consolidates slowly; greenhouse food crops are the volatile, hyped-then-humbled, capital-cycle half — a real-asset reshoring story that already burned a generation of growth investors. Neither is a public-equity sector today.

3. How big it is

Our federal ground-truth file for the 11141 level carries no ingested statistics — no Census establishment, employment, payroll, or receipts figures for this five-digit code. (It is empty by design; we do not invent numbers.) The sizing below therefore comes from the children's cited U.S. Department of Agriculture (USDA) sources, and from the U.S. Small Business Administration (SBA), each labeled.

• Mushrooms (111411). USDA National Agricultural Statistics Service (NASS) Mushrooms report, 2024–2025 crop year: 669.9 million lb sold for $1.096 billion at $1.64/lb farm-gate, up ~2% in volume and ~1% in value [2]. A separate, broader USDA series — the once-every-five-years Census of Horticultural Specialties — reports 415 operations, 933.0 million lb, and $1.503 billion for calendar-2024 [4]; the two are not comparable (different reporting periods, definitions, and measures) and should not be combined.
• Greenhouse and indoor food crops (111419). USDA's 2022 Census of Agriculture, Table 39: greenhouse vegetables and fresh-cut herbs were $981.7 million (11,465 operations, +31% since 2017) and greenhouse fruits/berries $36.4 million, for roughly $1.0 billion in farm-gate sales across ~140 million square feet (~3,200 acres) [3].
• Level rollup (approximate). Summing the children gives the 11141 level roughly $2.1 billion in farm-gate sales on the most-cited series (mushrooms $1.096B crop-year + greenhouse food $1.0B for 2022), or up to about $2.5 billion if the broader horticultural-census mushroom figure is used. Treat this as an order-of-magnitude total, not a precise one: the two children are measured by different USDA surveys in different reference years, so any sum mixes series.
• Small-business threshold. Both children carry an SBA size standard of $4.5 million in average annual receipts [5] — a program-eligibility line, not a revenue estimate, and a sign that most operations are small.

Undercount and coverage caveats. The general "business statistics" series most industries rely on — the Economic Census, County Business Patterns, Statistics of U.S. Businesses, and Nonemployer Statistics — largely exclude agricultural crop production (NAICS 111) [6], so they show almost nothing for this code; USDA surveys are the correct ground truth. Even those undercount at the edges: USDA counts any place with $1,000+ of sales as a "farm," sweeping in tiny growers, yet self-employed and hired agricultural labor is understated, and the economics of both children are concentrated in a few large private firms that never surface in public filings. On the greenhouse side, roughly 37% of operations report under 1,000 square feet under cover; on the mushroom side, NASS no longer prints a national grower count. Small/individual ownership therefore means the true operation count is fuzzier than the headline figures suggest, and consumption is far larger than domestic production (especially for greenhouse produce).

4. The investable universe — where value concentrates across the children

Value concentrates in large private growers in both children; listed exposure is thin, foreign, or distressed. (This section and Section 10 are the only places tickers appear.)

Mushrooms (111411) — private, family-and-PE. No U.S.-listed pure-play exists. The nearest listed operator is Hokuto Corp. (Tokyo: 1379), a mostly-Japan business that runs one U.S. specialty farm [21]; the U.S.-listed mushroom tickers (Farmmi, Nasdaq: FAMI, a Chinese trader that does not grow; Mushrooms Inc., OTC: MSRM, speculative) are off-target. The real operators are private: Monterey Mushrooms (largest fresh grower in North America), South Mill Champs (an Eos Partners PE-backed consolidator), and family names such as Giorgio, Phillips, and To-Jo [20].

Greenhouse/indoor (111419) — distressed public, stronger private. The 2020–2021 blank-check (SPAC — special purpose acquisition company) listings have almost entirely unwound. Local Bounti (NYSE: LOCL) is the clearest listed U.S. CEA name but is a loss-making microcap with disclosed listing and going-concern pressure [19]; Village Farms (Nasdaq: VFF) sold most of its U.S. produce business into private, PE-backed Vanguard Food in 2025 and pivoted the public company toward cannabis [18]. AppHarvest, AeroFarms, Kalera, Bowery, and Plenty all went bankrupt [11]. The healthy owners are private: Mastronardi/SUNSET (600+ U.S. acres), NatureSweet (Blue Road Capital), BrightFarms and Mucci Farms (Cox Enterprises), Windset, Gotham Greens, and Little Leaf Farms [12][17][18].

Common conclusion: across both children, the durable operating leaders are private, and the public route is either a foreign stock, a repurposed cannabis story, or a distressed microcap. Farmland real estate is a poor proxy for either — mushrooms grow in specialized buildings and greenhouses on engineered structures, not on cropland, so agricultural-land vehicles generally do not hold them.

5. How the money works

Both children earn money like a factory, not a field. The revenue identity is the same: saleable volume × realized price, where output is a function of growing area and yield per square foot, not acreage, and the difference between biological and saleable output (shrink) is the margin battleground.

• Two price tiers in each child. Commodity product runs at thin margins on high volume — button mushrooms at ~$1.53/lb, commodity round tomatoes barely clearing cost — while specialty and branded product (specialty mushrooms ~$5.83/lb, organics; snacking/on-the-vine tomatoes, berries, packaged herbs) carries the premiums where profit lives [2][3]. Blended margin improves with mix-shift toward the premium tier, but premium volumes are small.
• Labor and energy are the swing costs. Mushrooms are hand-harvested, so labor is the single largest cost; greenhouses live and die on energy — sunlight-based glasshouses are far cheaper per pound than fully enclosed vertical farms that rely entirely on artificial (LED — light-emitting diode) light, which is precisely why "grow everything in a warehouse" leafy-green models repeatedly failed [10].
• Perishability and cold chain. Both crops must move within days; growers have little pricing power once a crop is ready, and every unsold pound is a direct margin hit.
• Capital intensity. Modern mushroom rooms, composting, and cold chain need continuous reinvestment; a commercial greenhouse runs roughly $1–3 million per acre, with paybacks of 7–10+ years [10]. When capital got expensive in 2022–2023, the greenhouse child's "growth at all costs" models could not reach profitability and folded — the mushroom child, older and privately financed, largely did not.
• Underwriting KPIs (shared). Saleable pounds per square foot, realized price by variety and channel, labor and energy cost per pound, productive-area utilization, customer concentration, shrink/crop-loss history, maintenance capital expenditure, and debt-service coverage.

6. What drives demand

• Year-round, food-safe, local supply. Retailers want consistent, blemish-free availability 52 weeks a year; both children deliver it regardless of season, and recurring field-produce recalls push grocers toward controlled-environment supply.
• Premium and specialty trade-up. Specialty mushrooms (+10% to ~$95M) and the global functional-mushroom boom (lion's mane, reishi — a large, fast-growing supplement category, though most value is captured downstream) pull the mushroom child up-market [13]; snacking tomatoes, berries, and organics do the same for greenhouses.
• Plant-forward eating. Mushrooms' umami depth makes them the favored ingredient for blended/hybrid burgers and meat reduction.
• Reshoring and trade policy (a 2025 tailwind, mainly for greenhouses). Because most U.S. greenhouse produce is imported, trade policy moves domestic economics directly — in July 2025 the U.S. terminated the Tomato Suspension Agreement and imposed a 17.09% antidumping duty on most fresh Mexican tomatoes, raising import prices and helping domestic growers [9]. Mushroom growers face a milder version, pushing back on rising Canadian fresh imports [22].
• A demand caution (mainly for mushrooms). Per-capita fresh mushroom consumption has slipped ~10% since before the pandemic even as headline volume ticked up — a genuine near-term soft spot [2].

7. Regulation

Both children are regulated as fresh-produce agriculture, largely by the same agencies:

• Food safety. The Food and Drug Administration (FDA) Food Safety Modernization Act (FSMA) Produce Safety Rule governs growing, harvesting, packing, and holding for both, with Listeria environmental monitoring expected at fresh-pack facilities [14]. Imports run under a Foreign Supplier Verification Program — a live issue after imported enoki mushrooms caused a deadly multistate Listeria outbreak [23], mirrored by field-lettuce E. coli recalls that push buyers toward CEA greens.
• Organic. The USDA Agricultural Marketing Service (AMS) National Organic Program (NOP) certifies both; note two open questions — new mushroom-substrate provisions (compliance date March 22, 2027) and the still-contested status of hydroponic organic certification, which the U.S. allows but the EU, Canada, and Mexico do not [15].
• Labor. Both lean on the H-2A agricultural guest-worker visa administered by the Department of Labor (DOL); wage, housing, and immigration-enforcement rules are first-order cost and staffing risks — the mushroom industry reports running ~20% short on labor.
• Worker and site safety, trade, environment. Occupational Safety and Health Administration (OSHA) hazards (ammonia refrigeration, machinery, heat); antidumping/countervailing duties (the 2025 tomato order); and local zoning, water, wastewater, and (for mushrooms) composting-odor and spent-substrate permits.

Regulation is both a cost and a competitive barrier: larger operators spread compliance systems over more volume and clear demanding retailer audits more efficiently — an advantage that favors the consolidators in both children.

8. Consolidation

Consolidation into strong private hands is the shared trend, reached by opposite roads. The mushroom child has consolidated slowly and quietly for decades — a falling grower count against flat-to-rising output, with private equity (Eos-backed South Mill Champs) rolling up regional growers. The greenhouse child consolidated violently and recently: after ~$2.7 billion of venture money and a SPAC wave, a cluster of celebrated names failed (AppHarvest, AeroFarms, Kalera, Bowery, Plenty), and their assets migrated to disciplined private owners — Mastronardi absorbing distressed facilities, Cox combining BrightFarms and Mucci, Blue Road buying NatureSweet [10][11][12]. In both, scale wins in packing, cold chain, procurement, and retailer service, and glasshouse or growing-room capacity without retail access is not a moat. The main deal risk in either child is overpaying for capacity before proving durable yields, reliable labor, and repeat retail demand — with the added greenhouse-specific risk that imports (Mexican/Canadian), not domestic rivals, are the real competitive force.

9. Risks

• Labor and immigration — hand-harvested mushrooms with a structural worker shortage; H-2A wage and enforcement risk across both children.
• Energy — the largest variable cost for greenhouses and existential for artificial-light indoor models; a meaningful cost for mushrooms (heating, cooling, ventilation).
• Thin commodity margins and perishability — little pricing power once a crop is ready; shrink is a direct margin hit; a crop cannot be stored until conditions improve.
• Capital intensity and refinancing — high build costs and long paybacks; going-concern exposure when capital is expensive (the mistake that sank much of the 2021 greenhouse cohort).
• Biological/crop-disease risk — pathogens spread fast through enclosed monoculture systems (a factor in Bowery's collapse; a constant threat in mushroom houses).
• Food-safety and recall risk — a Listeria or E. coli recall carries outsized reputational and financial damage [23].
• Imports and trade-policy reversal — Mexican/Canadian greenhouse competition is the baseline, and the 2025 tomato duty could be litigated or negotiated away; rising Canadian mushroom imports pressure domestic pricing [9][22].
• Geographic and customer concentration — ~69% of U.S. Agaricus in one Pennsylvania county; a few grocery buyers hold purchasing power in both children.
• Ownership opacity — private companies disclose little, making leverage, margins, and share hard to compare in diligence.

10. How to invest, and the outlook

Public routes (limited, and different in each child). For mushrooms, focused listed exposure barely exists: the nearest operator is Hokuto (Tokyo: 1379), a foreign stock; U.S. mushroom tickers (FAMI, MSRM) are off-target or speculative [21]. For greenhouses, Local Bounti (NYSE: LOCL) is the most direct U.S. CEA name but carries real financing and listing risk, and Village Farms (Nasdaq: VFF) is now a cannabis-hybrid after divesting most of its produce business [18][19]. In both children, the more durable public exposure is indirect — diversified fresh-produce and agribusiness companies, and the picks-and-shovels suppliers (greenhouse structures, LED lighting, climate control and automation, substrates, packaging, cold chain, spawn) that sell regardless of which grower wins. Real estate investment trusts (REITs) mostly hold open-field cropland, not covered-crop facilities.

Private routes (where both children actually live). Direct equity in growers and grower-marketers; private-equity strategies on the South Mill/Eos and Mastronardi/Blue Road consolidation templates; preferred or convertible capital; asset-backed loans and equipment finance; greenhouse real estate and sale-leasebacks; and venture bets on functional-mushroom brands and surviving indoor niches (berries, microgreens, herbs). Underwrite at the facility level using the KPIs in Section 5.

Outlook. The two-child picture is a barbell of temperament. The mushroom half is defensive and cost-driven: a resilient staple with modest volume growth, a genuinely faster premium/functional layer, and labor-and-immigration policy as the biggest swing factor — an operating-and-private-capital story, not a stock-picking one. The greenhouse half is a real-asset reshoring story with a live 2025 import-duty tailwind, where the winners are sunlight-based greenhouse operators at scale and focused indoor niche players — decidedly not a return to the venture-funded "vertical farms everywhere" thesis. For the level as a whole, the base case is a resilient, ~$2-billion-plus farm-gate food category whose returns are earned through operating discipline and private capital, with execution in labor, energy, biosecurity, and pricing — not demand collapse — as the main downside.
