Solutions

No matter what crops you grow, what climate you are in, or what output goals you pursue, Sainpoly can provide you with a one-stop commercial greenhouse solution from design to delivery.

Vegetable Greenhouse Cultivation

Provide a stable production environment for vegetables such as tomatoes, peppers, cucumbers, and leafy vegetables throughout the year. We configure suitable lighting, temperature, humidity, and integrated water and fertilizer systems based on the growth characteristics of different vegetables to help you achieve your commercial planting goals of annual supply, uniform quality, and predictable yield.

Fruit Greenhouse Cultivation

We provide precise environmental control greenhouse solutions for berry fruits such as blueberries, strawberries, and grapes. By regulating the temperature difference between day and night, light intensity, and humidity curve, the sugar content, color, and product yield of fruits can be effectively improved, helping you obtain higher premiums in off-season marketing.

Horticultural Planting of Flowers

Provide a planting environment with controllable flowering period and stable appearance for high-end fresh cut flowers and potted flowers such as roses, lilies, and orchids. By precise photoperiod regulation, temperature management, and pest control, we help you accurately grasp the time to market and meet high-end flower market and export standards.

Seedling Cultivation & Planting

Provide professional seedling greenhouses with constant temperature, humidity, and controllable lighting for commercial seedling factories. By combining mobile seedbeds, supplementary lighting systems, and integrated water and fertilizer equipment, the seedling cultivation cycle is significantly shortened, the survival rate is improved, and the uniformity of seedlings is ensured, laying a solid foundation for subsequent field planting.

Cultivation of Medicinal/High-Value Crops

Provide a planting environment that meets GAP certification standards for medicinal crops such as ginseng, dendrobium, and saffron. By precise temperature and humidity control, soil/substrate customization, and environmental monitoring systems, the stable content of active ingredients is ensured to meet domestic and international pharmacopoeia standards and export certification requirements.

Hydroponic Cultivation

Integrating NFT shallow liquid flow, DWC deep water cultivation, vertical tower and other soilless cultivation systems, achieving efficient production with 80% water saving and a 3-fold increase in planting density. Suitable for crops such as lettuce, vanilla, strawberries, etc., it eliminates soil borne diseases, produces clean and safe agricultural products, and meets the needs of urban agriculture and high-end markets.

Aquaponic Cultivation

Integrating aquaculture with vegetable cultivation to build a "fish vegetable microbe" ecological cycle system. Fish excrement is decomposed by microorganisms into plant nutrients, purified by plants, and then returned to the fish pond, achieving a sustainable agricultural model of dual harvesting, zero emissions, and high added value.

Extreme Climate Planting

Provide customized greenhouse solutions for extreme weather conditions such as high temperature, severe cold, strong winds, and drought. By adopting typhoon resistant reinforced structures, double-layer insulation systems, evaporative cooling technology, or water-saving irrigation systems, efficient commercial planting can be achieved on land that was previously unsuitable for cultivation.

One-Stop solution

We Provide One-Stop Commercial Greenhouse Solution Services

Every Sainpoly greenhouse is unique. We reject standardized suite thinking and instead offer in-depth customized design based on your crops, local climate, site conditions, and investment budget.


From structural selection and covering materials to environmental control configuration and supporting systems, we offer hundreds of optional combinations to ensure that the final delivered greenhouse is not only usable, but also an efficient and high return production asset.

Customization Process
You provide crop planting, target yield, site size, local climate data, and budget range. Our sales consultants and design team work together to identify the key points of the project.
The design team provides 3D renderings, CAD construction drawings, load calculations, and detailed quotations. Before confirming the plan, it can be modified multiple times to ensure that it fully matches your expectations.
After the order is placed, the factory schedules production. We use precision equipment such as robot welding and laser cutting, strictly implement the three inspection product control, and ensure zero defects in the factory products. Provide CE certification and related testing reports.
Provide on-site technical guidance or turnkey installation based on the mode you have chosen. After project delivery, you will enjoy a one-year warranty, lifetime technical support, 7×24-hour remote troubleshooting, and free online training every year.
