Before making any investment cost analyses, the issue that everyone agrees on is that whether it a winter seoson summer season growing project, glass greenhouses always offer more advantages to the growers rather than the plastic ones. In the regions where winter production is carried out, planting in all greenhouse types starts in August and production is ended by June due to the extreme hot weather.
Especially in the dark months such as November, December, January, February and March,when the sunlight required fphotosynthesis process in production, thanks to the transmittance of more than 90%, the glass greenhouse offers more sunlight than the plastic greenhouses having a light transmission of 60% - 70%; and gives up to 25% more products in production than plastic greenhouse.
This advantage allows the fruit to be sold at higher prices in the winter months when it is difficult to find it and lets the grower make more profit. Under these circumstances, the grower can make +25% profit. Glass greenhouses provide fuel savings from 20% uo to 50% in energy consumption compared to plastic greenhouses. In the greenhouses where summer production is carried out, the advantages it offers in the winter months with minimum cold and daylight are of great importance fevery grower.
