Weifang Greenday Agriculture Tech. Co., Ltd has been building greenhouses since 2001. Our customers grow a variety of crops ranging from vegetables to flowers, nursery stock to tree seedlings and medicinal to nutraceutical crops.

We also count a number of governmental agencies and institutions among our clientele.We pride ourselves on building long-lasting relationships with our customers.

We'd be happy to provide a comprehensive listing of completed projects on request.Our aim is to supply our customers with greenhouses and systems, using the best applicable technology.

We keep constantly informed about the latest developments in the horticultural industry and translate this into advice that comes with the product.

Every customer is different, and no project is the same. We view each job as a fresh challenge but also bring the knowledge gained from our extensive experience.

We work closely with our customers and exchange ideas to get a result that is best suited to their needs. With their roots in the horticultural industry, our engineering staff members are able to combine technology and horticulture into a very workable investment for the greenhouse owner.

 We sincerely hope to cooperate with you!

Production of agricultural crops depends on two main factors: solar radiation and climate. Plants need solar radiation for photosynthesis, and the interior environment (temperature and humidity) must match the plants requirements. Generally greenhouses can sustain such conditions, but need fuel based heating for sustaining through the cold winters.

A passive solar greenhouse is a greenhouse heated entirely by sunlight, with no additional fuel based heating.

Passive solar greenhouse absorbs as much as possible solar energy (sunlight during the day) in the winter season for the following gradual emission of accumulated solar energy for heating purposes.

Operation principles

The main operation principle of a solar greenhouse lies in accumulation and storage of solar energy (sun radiation) during daytime and gradual release of the energy (heat) during the night.

Thus, solargreenhouse:

-     Collects the maximum amount of solar radiation during the day;

-     Efficiently stores the heat collected from sun radiation during the day;

-     Releases this heat to the interior of the building during the night;

-     Heat losses are reduced by insulation of the whole greenhouse;

-     Can be ventilated to avoid overheating.
