Dıfference of Greenhouses



One of the most important issues that should be presented to our valued investors and producers, the difference between glass greenhouse and other greenhouse types. You want to build a modern hydroponic greenhouse, and this decision brings a serious investment cost. So what kind of decision should you make, what type of greenhouse should you invest in? We want to offer you the difference and advantages of Venlo type glass greenhouses, which are the first to come to mind when said the Netherlands, which ensures optimum food safety, if any, we would like to mention the disadvantages on below.

In your Swot analysis that you will make before your investment decision, it is likely that your investment decision will go in a different direction than you first thought.

1- The lifetime of the glass greenhouse construction is calculated over 49 years. The reason for this is 6kg iron and 3kg aluminum which are used in m². In the framework and construction of many different greenhouse types, there are no such raw materials and quantity. 

2- The service life of the glass material as coating material is calculated over 49 years. Due to being tempered glass on the roof; storm, tornado, hail, snow, heavy rain, fire, sandstorm and similar disasters will not give any damage. However, other short-term coating materials will cause damages under the aforementioned climatic conditions and will cause damage to all plants below it.

3- Since there are no UV, IR and chemical loads on the glass as the coating material, no reaction will occur in the plants.

4- Glass material used as a coating material is a one-time investment. Other short-term coating materials should be changed maximum 3 years after. The biggest problems encountered during this change; due to increase in foreign exchange prices, price of raw materials, high labor costs and lack of expert staff in the market, it is the share that every 3 years from the production period of your business. You will also appreciate that the planting period can be early and your production period is long-lasting, will bring you financial gain.

5- Like other coating materials, the glass coating material does not cause or contribute to moisture in the greenhouse. It allows the current moisture adhering to the glass surface, provides easy slipping to the grooves without allowing the surface adhesion coefficient. However, other coating materials, due to their high surface fastness to hold, drip drops of the moisture from the greenhouse top onto the plants unfortunately it allows the formation of pathogens such as bacteria and viruses.

6- The assertion; 1% excess surplus brings 1% more harvest, is a known reality in modern greenhouse. Glass greenhouses with a light transmittance of more than 97%, especially in the dark winter months, have 4% loss of light entering the glass greenhouse, while other greenhouse types have a loss of about 30%. Even in warm climates such as Antalya, which produces winter productions, glass greenhouses receive production surplus in terms of other greenhouse types in the same region. There are already higher harvest quantities in the summer production regions. The profitability turnover of this surplus, which is over 8%, despite the high number of closed air in winter production places, due to the light transmission of the glass, plant work is at a high level, It is greater than the numerical sense.

7- High light transmittance in glass greenhouses, provide brighter fruits, more homogeneous, harder and therefore have a long shelf life.


In the winter months, faster and more penetration of light into the plant allows faster frying when the fruit is more expensive in the market.

8- The yield can be increased up to about 15% via diffuse fluid where can be used on external surfaces of glass greenhouses, reduce fogging usage by 60% and by eliminating slab heat, you can eliminate the risk of root tip rot and minimize calcium deficiency.

9- Energy consumption costs in glass greenhouses are 35% to 40% less than in plastic greenhouses. In times when days are shorter, light and heat penetrate more quickly. Due to the optimum measurement of the roof volume dimensions and the advantage of insulation, heat loss is minimal compared to other types of greenhouses. Due to the small number of reducer, electricity consumption is also less. The contribution of thermal screen to energy saving is about 40% in glass greenhouse and the life of thermal curtain is about 3 years longer than other greenhouse types.

10- Greenhouses are easily ventilated in 45 - 50 minutes, while other greenhouse types are ventilated in 3 - 4 hours by opening of the roofs of glass greenhouses. Since the window positioning is opposing in other greenhouse types, it may not be possible to open the roofs in windy weather when compared to glass greenhouses.

Even only a part of all these titles, if you have realized that the glass greenhouse is really advantageous, before the deep analyzes, even with the simple calculations, you will get the sum of the differences between the production cost and depreciation expenses that you will obtain through the production quality and harvest differences that you will gain-you can see the reality of; other greenhouse types with Varnet production Glass Greenhouse first investment cost difference can be easily closed in 1 to 2 years. Varnet is always ready to accompany you with its experienced staff.
