Tunnel Greenhouse

Tunnel Greenhouse: A Practical, Adaptable Solution for Global Growers

In modern agriculture, growers across the world seek greenhouse options that balance reliable performance, reasonable costs, and flexibility—whether scaling operations or adjusting to local climate conditions. Our Tunnel Greenhouse (also referred to as a hoop house) is designed to meet these needs, featuring a simplified yet effective structure that creates stable growing environments for various crops while keeping initial investment and maintenance requirements manageable. Suitable for small-scale family farms, commercial growing operations, and research facilities alike, this greenhouse adapts to diverse regional needs—from the sunny landscapes of Africa to the temperate zones of North America and Europe.

1. Streamlined Hoop Structure: Simple Design with Reliable Performance

The tunnel greenhouse’s classic curved “hoop” frame is engineered to prioritize functionality without unnecessary complexity, making it a practical choice for growers focused on efficiency and ease of use.

Weather Resilience: The rounded hoop design (available in widths from 6m to 12m, customizable) distributes wind pressure evenly, supporting resistance to wind speeds of up to 100km/h—offering greater stability than flat-roof greenhouse alternatives. For areas prone to snow, the steep curve helps prevent snow buildup (snow slides off naturally), reducing the risk of frame stress and minimizing the need for manual snow removal.

Space Efficiency: With a clear-span design (no internal support poles) and peak heights ranging from 2.5m to 4m, the tunnel greenhouse maximizes usable space for row planting, vertical growing setups (such as trellises for tomatoes or cucumbers), and small-scale equipment (like hand carts or irrigation tools). This layout helps improve planting density compared to many traditional small greenhouses.

Easy Installation: The prefabricated hoop frame (assembled with bolt-on connections) can be set up by 2-3 people in approximately 1-2 days for a 30m-long unit—no specialized welding or advanced construction skills are required. Optional ground anchors (for temporary installations) or concrete footings (for long-term use) ensure stability on various terrains, including sandy soils and rocky ground.

2. Climate Adaptability: Tailored to Local Growing Conditions

A key advantage of the tunnel greenhouse is its ability to adjust growing environments across different climates, helping growers extend growing seasons, protect crops from pests, and reduce losses caused by unpredictable weather.

Ventilation Options for Temperature Control:

Passive Ventilation (Standard): Sidewalls can be rolled up (using manual or motorized roll-up systems) to enable cross-airflow, supporting natural cooling during warmer weather. Optional ridge vents add top-down airflow, helping prevent hot air from accumulating at the ceiling—useful for crops sensitive to heat, such as lettuce and spinach.

Active Ventilation (Add-On): For regions with extreme climates (e.g., hot, humid areas in Southeast Asia), the greenhouse can be equipped with exhaust fans and intake shutters. These work together to circulate air and may lower internal temperatures by 5-8°C when needed. This system can integrate with thermostats for automated operation, reducing the need for manual monitoring.

Insulation and Heat Retention: The greenhouse’s covering options (detailed below) provide basic insulation, helping retain heat overnight and during cooler seasons. For growers in temperate or cold regions (e.g., Northern Europe, Canada), adding a second inner layer of polyethylene film creates a “thermal barrier” that may raise internal temperatures by 4-6°C—supporting an extended growing season (e.g., enabling early spring planting of peppers or late fall harvesting of kale).

Crop Protection: The tightly sealed covering helps block common pests (such as aphids and caterpillars) and wildlife (like birds and rabbits) from damaging crops, reducing reliance on chemical pesticides. It also shields plants from heavy rain, hail, and intense UV rays—helping prevent soil erosion, leaf damage, and sunscald (a common issue for tomatoes and peppers).

3. Durable, Cost-Effective Materials

We select materials that balance longevity, performance, and affordability, ensuring the tunnel greenhouse delivers consistent value over time.

Frame Materials:

Galvanized Steel (Standard): 1.5mm-2.0mm thick galvanized steel hoops that resist rust, corrosion, and UV degradation. The steel is lightweight yet sturdy, with an expected lifespan of 15 years when properly maintained.

Aluminum (Optional): For growers in coastal areas (where salt spray is a concern) or those seeking a lighter, rust-proof alternative, aluminum hoops (1.8mm thick) offer an expected 20-year lifespan and easier transport due to their lower weight.

Covering Options:

Polyethylene Film (Economical Choice): 6mil or 8mil UV-stabilized polyethylene film that transmits 85-90% of visible light, blocks 98% of harmful UV rays, and resists tearing. It is easy to replace (typically every 3-5 years) and cost-effective—well-suited for small-scale growers or seasonal use.

Polycarbonate Sheets (Premium Choice): 6mm single-wall polycarbonate that provides enhanced durability (shatterproof and hail-resistant) and a longer lifespan (backed by a 10-year warranty). It transmits 90% of visible light, retains heat better than polyethylene film, and is ideal for permanent operations or crops requiring consistent growing conditions (e.g., medicinal herbs, seedlings).

Accessories: High-quality EPDM gaskets (for sealing ridge vents and doorways) help prevent water leakage; heavy-duty zipper doors or roll-up doors enable easy access while keeping pests out; and built-in drip irrigation line holders keep irrigation systems organized.

4. Versatile Applications: Grow a Wide Range of Crops

The tunnel greenhouse’s adaptability makes it suitable for various crops and growing objectives—whether you sell produce at local markets or supply large retailers.

Crop Compatibility:

Vegetables: Works well for warm-season crops (tomatoes, peppers, cucumbers, zucchini) and cool-season crops (lettuce, spinach, carrots, broccoli). The controlled environment supports consistent growth, helping produce higher-quality crops with fewer blemishes.

Flowers: Protects delicate flowers (roses, gerberas, petunias) from wind and rain, extending their vase life and supporting year-round production when paired with optional heating systems.

Seedlings & Propagation: Creates a stable environment for starting seeds (e.g., tomato seedlings in spring) or rooting cuttings, supporting improved germination rates compared to outdoor planting.

Specialty Crops: Suitable for organic crops (by reducing pesticide use) and high-value crops (e.g., strawberries, raspberries) that require protection from birds and harsh weather.

Climate-Specific Use Cases:

Arid Regions (e.g., Australia, Middle East): The greenhouse helps reduce water evaporation by 30-40%, making it compatible with water-efficient drip irrigation systems. Optional shade cloths can block excess sunlight, preventing crop wilting.

Tropical Regions (e.g., Brazil, Thailand): Roll-up sidewalls and ridge vents support maximum airflow, helping reduce humidity and lower the risk of fungal diseases (e.g., powdery mildew on roses).

Temperate Regions (e.g., USA, France): Extends growing seasons (e.g., supporting tomato growth from April to October instead of June to August) and protects crops from late frosts (a common threat to spring plantings).
