The opening time and duration of skylights in glass greenhouses need to be determined comprehensively based on environmental conditions, crop needs, and greenhouse structure. The following are specific suggestions and analyses: I. Basis for Determining Opening Time Temperature Threshold Summer High-Temperature Periods: When the internal temperature of the greenhouse exceeds the upper limit for crop growth (e.g., 30℃-35℃), skylights should be opened promptly to cool the greenhouse and prevent heat damage. Winter Nights and Early Mornings: If the outside temperature is below 5℃ or the temperature difference is too large (e.g., indoor-outdoor temperature difference > 15℃), opening should be delayed to prevent cold air from directly blowing onto the crops. Daytime Dynamic Adjustment: Morning: When the greenhouse temperature rises to 25℃-28℃, gradually open the skylights 10%-30%, using shading nets to reduce radiant heat. Afternoon: During the peak temperature period (12:00-15:00), skylights can be fully opened, but humidity control is necessary. Evening: One hour before closing, gradually reduce the opening to avoid a sudden drop in temperature. Humidity Thresholds High Humidity Environment: When relative humidity > 85% and lasts for more than 2 hours, open the skylights in conjunction with the circulating fan to accelerate dehumidification and prevent diseases. Low Humidity...

Greenhouse Diffuse Glass – The Complementary Regulation of Light Transmittance, Haze, Accumulated Temperature, and Crops The light transmittance, accumulated temperature, and haze of greenhouse anti-reflective glass are closely related to plant growth. They collectively influence the light environment within the greenhouse, thereby regulating photosynthesis, morphogenesis, and yield and quality of plants. Understanding the relationship between these four factors allows for a clearer understanding of the operating principles of greenhouses. 1. Light Transmittance and Plant Growth Light transmittance is a key indicator of the ability of greenhouse covering materials to allow light to pass through, directly affecting the energy supply for plant photosynthesis. The light transmittance of glass greenhouses is typically between 91.5% and 97.5%. Too low a light transmittance leads to insufficient light, inhibiting plant growth; while too high a light transmittance (such as in summer) may cause excessively high temperatures, leading to excessive vegetative growth. Therefore, selecting high-transmittance, non-drip specialized greenhouse glass and regularly cleaning and maintaining it are fundamental to ensuring efficient light utilization. 2. The Regulatory Role of Accumulated Temperature Accumulated temperature (effective accumulated temperature) is the total heat required for plant growth and development, directly related to light intensity and temperature within the greenhouse. High-transmittance glass...

In commercial production, the most widely accepted rule of thumb for growers is that a 1% increase in sunlight equals a 1% increase in crop yield. Therefore, it is a common understanding that the glass covering used in greenhouses should allow as much sunlight as possible into the greenhouse to achieve maximum crop photosynthesis. Diffuse greenhouse glass，In greenhouse cultivation, diffuse light properties are increasingly used and is always a topic of discussion, in screening, roof-washing and grow lights. Diffuse light is light that is scattered and distributed evenly in all directions. Having this diffuse property on the roof of a greenhouses, limits hard shades. Reducing shaded areas is desired for a homogenous cultivation. Especially with crops that grow vertically (tomatoes, peppers and cucumber) diffuse light has a positive effect as light can penetrate further into the crop. The lowest leafs can also take in sunlight, increasing photosynthesis and thus, crop growth. Crops can also handle diffuse light better and more efficiently than direct sunlight.The level of light diffusion is quantified by a specific number known as the haze factor. This number represents the proportion of incoming light, coming in at a perpendicular angle, that deviates more than 2.5° ，from a...

As the most advanced greenhouse technology in agriculture, glass greenhouses are unique in all aspects. It perfectly solves the problem of poor local land, and delicious and tender vegetables can be eaten no matter what kind of bad weather. The focus of glass greenhouses is sealing. Good sealing can ensure the growth of fruits and vegetables without the interference of pests and diseases. The controllable temperature in the greenhouse ensures that we can eat fresh vegetables in winter.The greenhouse has good sealing, advanced planting technology, and management concepts, and it is inseparable from the light of nature.Good light can ensure that fruits and vegetables can fully photosynthesize. The top of the glass greenhouse is the main source of light. The light transmittance of the glass is crucial, and the thickness is an important factor affecting the light transmittance;The glass thickness specifications used in glass greenhouses are basically finalized, which is 4mm ultra-white tempered single glass.The basic ultra-white tempered glass has a light transmittance of 91.5%—92%. The ultra-white glass after coating can reach a light transmittance of about 99%. Compared with other thicknesses of glass, the ultra-white tempered glass with a thickness of 4mm weighs 10 kilograms per square meter. In...

The mainstream choices for glass greenhouse covering materials are diffusing glass and anti-reflective glass. These types of glass are mainly available in the following specifications: 1. Light transmittance: 91.5%, 97.5% (Recommended) For high-standard greenhouses, anti-reflective glass with 97.5% light transmittance is recommended. Diffusing glass with 91.5% light transmittance is also sufficient. 2. Thickness: 4mm (Recommended), 5mm 4mm glass is recommended. Compared to 5mm, 4mm glass has 1% higher light transmittance, and it is also cheaper. 3. Haze: 50 haze, 70 haze (Recommended), 30 haze Currently, the haze specification used in Dutch greenhouses is mostly 70 haze, with 50 haze and 30 haze also being common. 4. Dimensions: 2m x 1m x 4mm (It is recommended to consult with the factory to inquire about sheet shortages, size design, etc.) The dimensions of greenhouse diffuser glass and anti-reflective glass need to be discussed with the glass factory in advance before design to improve glass cutting efficiency and avoid sheet shortages. Greenhouse diffuser glass and anti-reflective glass have the following functions: High light transmittance, long lifespan, high safety, full fog resistance, and no dripping. High light transmittance ensures sufficient light source inside the greenhouse, and the higher transmittance in the light wavelength range...
