01 · Market overview: USD 300 million and growing.
The US growing media market was valued at USD 2.4 billion in 2025, projected to reach USD 3.8 billion by 2033 at a CAGR of 6.1 %.[1] Peat moss remains dominant at USD 545 million in 2025, but coir is the fastest-growing organic substrate segment.[2] North America accounts for approximately 20 % of global coir demand, roughly USD 83 to 94 million under the narrow definition. Under a broader classification that includes all coir substrate products, the US coir market is valued at approximately USD 300 million in 2025, expected to grow to USD 450 million by 2033 at a CAGR of 5.2 %.[3]
US covered greenhouse production area reached 1.04 billion square feet (96.6 million m², approximately 25,700 acres) in 2025, up from 969 million ft² in 2024. The number of floriculture producers totaled 11,728, and total floriculture crop sales reached USD 8.41 billion, up 25 % from 2024.[4] The US greenhouse produce sector reached USD 3.2 billion in 2025, with greenhouses accounting for 25 % of US specialty crop output. Over 45,000 commercial greenhouse farms in the US use coconut coir substrates.[5]
Controlled environment agriculture
The North American commercial greenhouse market was valued at USD 7.65 billion in 2025, projected to reach USD 8.25 billion in 2026 at a CAGR of 7.8 %.[6] The broader US CEA market (greenhouses, vertical farms and indoor operations) is growing at 14 to 18.1 % CAGR. CEA expansion is a primary driver of coir substrate demand as operations switch from peat-based to coir-based systems.
02 · Import volumes and supply origins.
The United States is the world's largest coir importer, accounting for 39 to 48 % of global coconut coir trade depending on HS code classification. The broader US coir product import volume exceeds 650,000 metric tons annually across all coir categories (fiber, pith, chips, mats).[8]
| Origin | Share of shipments | Notes | Source |
|---|---|---|---|
| India | 58–82 % | Dominant supplier across all categories; at least 47 exporters serve 66 US buyers | Volza |
| Sri Lanka | 11–21 % | Second-largest supplier; strong in grow bags and professional-grade substrate | Volza |
| Vietnam | 3–42 % | Surged to top fiber exporter to the US with 3,222 shipments; US$ 82 million in first 7 months of 2025 | Produce Report |
| Mexico | Emerging | Proximity advantage: containers by rail or truck; producers in Colima supply own greenhouse sector | Floral Daily |
| China | ~9 % | 58 shipments; smaller supplier | Volza |
Shipment share varies by HS code and product category. Vietnam leads in coir fiber; India leads in coir pith.
Coir prices surged 60 to 70 % compared to January 2024, squeezing margins but not slowing adoption. The long-term US coir market CAGR is 5.2 % through 2033. Short-term fluctuations reflect price spikes, tariff uncertainty and inventory destocking rather than structural demand decline.[3]
03 · Buyer segments: greenhouses, cannabis, nursery, retail.
Greenhouse vegetables
Commercial greenhouse tomato, pepper, cucumber and strawberry operations are the largest professional buyers of coir substrate. Coir slabs and grow bags replaced rockwool in many facilities because coir is more efficient, less expensive to dispose of and the spent material goes to compost. The US horticulture sector consumes approximately 60 % of imported coir.[3] A single facility in Santa Maria, California, grows tomatoes and cucumbers on coir substrate across 46 hectares (114 acres) in Ultra-Clima greenhouses, making it the largest single-site greenhouse vegetable facility in the US at 168 acres total.[9]
Cannabis and hemp
Coco coir is one of the most popular growing media for both commercial cannabis facilities and home grow operations. It is difficult to overwater, the particle structure aerates the root zone well and it is renewable. The US legal cannabis market generated approximately USD 33.8 billion in retail sales in 2025.[10] Coir is commonly used across all major legal markets: California, Colorado, Oregon, Michigan and Massachusetts. One major hydroponic retailer reports that its coco coir products constitute over 30 % of cultivation revenue, targeting 35 %.[11]
| Parameter | Cannabis specification | Source |
|---|---|---|
| Raw substrate EC | < 0.5 mS/cm | Coco For Cannabis |
| Nutrient solution, vegetative | 1.3–1.7 EC | Sensi Seeds |
| Nutrient solution, flowering | 1.5–2.0 EC | Sensi Seeds |
| pH range | 5.5–6.5 (optimal 5.5–6.0) | Industry standard |
| Grow bag sizes | 3-gallon (SOG) and 5-gallon (full cycle) | Harris Seeds |
| Pith:chip ratio | 70:30 typical | Industry standard |
Nursery and floriculture
The US floriculture sector totals 11,728 producers with USD 8.41 billion in crop sales.[4] Coir pith is used in propagation media, container mixes and soil amendments. Nurseries typically accept EC below 1.0 mS/cm for general use and below 0.5 mS/cm for seed starting.
Retail garden
The large home improvement chains carry dedicated coir categories. Retail prices for 5 kg (11 lb) compressed blocks range from USD 12.74 to 25.00. Consumer bricks (650 g) sell at USD 15 to 20 for a 5-pack. The online channel, led by Amazon, has dozens of brands with several thousand monthly unit sales for top SKUs.[12] Category range at retail runs USD 6.98 to 44.99.
04 · Regional greenhouse clusters.
| Operation | Location | Size | Coir confirmed |
|---|---|---|---|
| Large single-site greenhouse (Santa Maria) | California | 168 acres (46 ha on coir) | Yes, confirmed |
| Major greenhouse vegetable facility | Delta, Ohio | 175 acres (building) | Likely (sector norm) |
| Largest single-build greenhouse (Oneida) | New York | 64 acres / 2.78 M ft² | Likely (sector norm) |
| Multi-site greenhouse operation | Kentucky (4 sites) | 165 acres total | Likely (sector norm) |
| Urban rooftop greenhouse network | NY, IL, TX | 38 M ft² | Likely (sector norm) |
Michigan has 50.4 million ft² of greenhouse production space. Multiple additional locations operate across Texas and Utah.
05 · Logistics from Brazil: 8 to 18 days to the East Coast.
The Port of Pecem in Ceara, Brazil, is 90 km from Carve's processing site in Paraipaba. The geographic position of Northeast Brazil on the Atlantic places it closer to the US East Coast than any Asian coir origin.
| Route | Transit time | Source |
|---|---|---|
| Pecem to Newark | 8–9 days | APM Terminals Pecem |
| Pecem to Savannah / Miami | 10–14 days | APM Terminals Pecem |
| Pecem to US East Coast (general) | 8–18 days | iContainers |
| India / Sri Lanka to US East Coast (via Suez) | 28–35 days | Industry standard |
| India / Sri Lanka to US East Coast (via Cape) | 35–45 days | Industry standard |
East Coast ports
New York / New Jersey is the largest East Coast container complex and has direct Pecem service (Hapag-Lloyd). Savannah, Georgia is the third-largest US container port and the primary agricultural commodity gateway with CSX and Norfolk Southern intermodal connections to the Southeast and Midwest. Miami handles efficient agricultural product handling as a Latin American and Caribbean gateway. All three have USDA-CBP inspection facilities for agricultural imports.[13]
Container freight rates
| Route | 40 ft container rate (2026 est.) | Source |
|---|---|---|
| Asia to US East Coast | USD 2,800–5,000 / FEU (down 30–35 % from 2025 peaks) | SeaRates |
| Colombo to US (indicative) | USD 3,050 / 20 ft · USD 3,350 / 40 ft | Suaid Global |
| Brazil to US East Coast | Lower (shorter route, established trade lanes) — quote-based | Industry |
Pecem's geographic advantage translates to lower freight costs per container versus South Asian origins.
USDA APHIS import rules
APHIS regulates plant and plant product imports through 7 CFR 319. Dried, processed coconut coir (pith, fiber, chips) that is free of pests and soil is typically admissible. A phytosanitary certificate from the exporting country's NPPO (Brazil: MAPA) is standard practice. Heat treatment or methyl bromide fumigation may be required if pests of concern are detected.[14]
