The Sainpoly Venlo greenhouse is the preferred choice for high-value crops and cold regions. Adopting double-layer insulated tempered glass and aluminum alloy frame, the light transmittance exceeds 91% and the insulation performance is excellent. Integrated insulation curtain and heating interface, can maintain a temperature of 10℃ or above indoors at night at -35 ℃ outdoors. Suitable for tomatoes, colored peppers, high-end flowers, etc., achieving stable production and high quality throughout the year.
The Sainpoly hydroponic greenhouse integrates advanced soilless cultivation systems such as NFT, DWC, and vertical towers. Compared to traditional soil cultivation, it saves 80% water and increases planting density by three times. Controlled environment to eliminate soil borne diseases and achieve annual production of lettuce, vanilla, strawberries, and other crops. We provide a complete system design from nutrient solution management to automatic irrigation, helping you achieve cleaner and higher yields.
The Sainpoly Gothic greenhouse adopts a pointed arch design, which naturally slides snow and has strong wind resistance, making it particularly suitable for snowy or windy areas. The structure is economical and practical, with hot-dip galvanized steel frame and single-layer or double-layer film coverage. Suitable for medium-sized farms, seasonal vegetable cultivation, or berry production. Modular components are easy to assemble, balancing durability and cost-effectiveness.
The semi enclosed greenhouse of Sainpoly is an advanced choice for environmental control technology. Through active air circulation and positive pressure system, energy consumption is reduced by 30%, while maintaining uniform distribution of temperature, humidity, and CO ₂ throughout the planting area. This design reduces disease pressure and significantly improves the yield and quality of high-value crops such as tomatoes and cucumbers. Suitable for investors who pursue the highest investment return and top quality.

Different types of greenhouses have their own emphasis on insulation, transparency, disaster resistance, cost, and other aspects. The following table helps you quickly determine which greenhouse is most suitable for your project.
| Greenhouse type | Insulation performance | Light transmittance | Wind and snow resistance | Applicable climate | Cost level | Major crops |
| Multi-span greenhouse | Medium (with added insulation curtain) | 85%-90% | Wind resistance level 10 snow load of 0.5kN/㎡ | Temperate/Subtropical | ★★☆ | Vegetables, flowers, lettuce and seedlings |
| Venlo greenhouse | Excellent (double-layer glass+insulation curtain) | ≥91% | Wind resistance level 12, snow load 0.8-1.0kN/㎡ | Extreme Heat Zones/Cold Zone | ★★★★ | Tomatoes, colored peppers, high-value crops, lettuce |
| Hydroponic greenhouse | According to the covering material | According to the covering material | Based on the structure | All climate (indoor) | ★★★ | Leafy vegetables, herbs, strawberries, lettuce |
| Gothic greenhouse | Medium (double-layer film can be added) | 85%-90% | Wind resistance level 10, snow load of 0.5kN/㎡ | Snowy/windy areas | ★☆ | Vegetables, berries, seasonal planting, lettuce |

Greenhouse system supporting services
In addition to the main structure of the greenhouse, Sainpoly also provides complete supporting system integration services. All systems can be purchased separately or integrated into greenhouse projects, achieving a one-stop upgrade from framework to smart farm.
The Sainpoly intelligent environmental control system automatically monitors and adjusts temperature, humidity, light intensity, and CO ₂ concentration. Sensors scattered throughout the greenhouse transmit data to the central PLC controller, which automatically triggers fans, heaters, sunshades, or CO ₂ generators. View environmental data and adjust parameters remotely through a mobile app. This system is the key to achieving stable production throughout the year and reducing labor costs.
We provide drip irrigation, sprinkler irrigation, tidal irrigation systems, and integrate water and fertilizer integrated units. Accurately mix nutrient solutions according to different growth stages and deliver them to each crop. The system can recycle and disinfect the return water, reducing fertilizer waste by more than 30%. Suitable for soil cultivation and soilless cultivation.
The Sainpoly sunshade system (internal/external, manual/electric) reduces excessive sunlight and heat in summer, protecting crops from burns. Thermal insulation curtains (made of aluminum foil or woven fabric) lock in heat at night, reducing heating costs by 40%. All screens are durable and UV resistant, and can be customized with different shading rates.
We provide top opening window, side rolling film, fan wet curtain cooling system, high-pressure spray. The top and side windows provide natural ventilation. In hot climates, the fan wet curtain system can cool down by 8-12 ℃. High pressure spray reduces temperature and increases humidity, suitable for dry areas.
