Single Tunnel Greenhouse: Start Growing Year-Round | SHG
What Is a Single Tunnel Greenhouse?
A single tunnel (high tunnel) greenhouse is a freestanding arched structure covered with high-performance plastic film, designed for direct soil cultivation.
It requires no complex foundation, no special approval, and installs quickly. It is the first and most reliable step for growers moving from open-field farming to protected agriculture.
Why Now Is the Best Time to Invest in a Single Tunnel Greenhouse：
| Indicator | Data | Explanation |
| Market Growth | Global tunnel greenhouse market growing 7% annually, projected to reach $500 million by 2033 | Small and mid-scale cultivation is becoming mainstream |
| Payback Period | 1–2 years (traditional greenhouses: 3–5 years) | Low investment, fast results |
| Yield Improvement | Harvest period extended by 6–8 weeks, better product quality | Multi-purpose structure, double efficiency |
Four Core Advantages
- Low Cost, Fast Payback
- Cost: $1.5–3 per ㎡(only 1/3 to 1/5 the cost of multi-span greenhouses)
- Payback period: 1–2 years, ideal for growers with limited budgets
- Fast Installation & High Flexibility
- No foundation required; installation completed in 1–2 days
- Can be built on gentle slopes and even relocated if needed–perfect for leased land and crop rotation
- Strong Protection & Stable Yield
- Effectively defends against strong wind, hail, and pests
- Reduces disease and pest damage, improves marketable yield
- Scalable Design for Business Growth
Start with one tunnel, expand to a full tunnel farm gradually
Modular design supports upgrades: automatic ventilation, irrigation, and environmental monitoring
| Item | Single Tunnel Greenhouse | Multi-span Greenhouse |
| Cost | $28–110 per unit (DIY kit) | $2,200–36,000+ |
| Installation | 1–2 days, no foundation needed | Several weeks, requires leveled site |
| Climate Control | Manual roll-up ventilation | Automatic heating, cooling & fan systems |
| Growing Season | Early spring & late autumn | Year-round production (with heating) |
| Best Use | Soil cultivation, trial planting | Soilless farming, high-value crops |
Single Tunnel vs. Multi-span Greenhouse: Which to Choose?
Technical Specifications & Selection Guide
Standard Specifications (SHG)
| Item | Specifications |
| Span | 6m / 7m / 8m / 10m / 12m |
| Roof Type | Arch / Peak / Flat / Round |
| Wind Load | 0.35 KN/m² |
| Snow Load | 0.20 KN/m² |
| Galvanization | 275g/m² (hot-dip galvanized) |
| Film Life | Standard: 3–4 years; anti-drip & UV-resistant film lasts longer |
Selection Logic
- Cold & snowy regions: Reinforced frames + concrete anchoring + snow-resistant film
- Hot & rainy regions: Enhanced ventilation + shade net + high eave design
- Tall crops (tomato, cucumber): 10–12m span + eave height ≥ 2m
- Leafy greens (lettuce, spinach): 6–8m span recommended
Your Expansion Path: From One Tunnel to a Full Farm
Stage 1: Single tunnel + drip irrigation + manual management → test the market
Stage 2: Tunnels in rows + shared water system → scale efficiency
Stage 3: Add climate control + automatic irrigation → improve precision
Stage 4: Zoned management + off-season production → year-round output
