Ten percent higher light incidence in greenhouse

Every percent can be converted into higher production. Mardenkro offers a package of solutions (AntiReflect, AntiCondens, andGS-4 glass cleaning) designed to improve the incidence of light into a greenhouse by as much as ten percent.

Mardenkro is known for coatings that reflect excessive sunlight. In the past, the ReduSol coating represented a breakthrough in comparison to traditional chalk products. Now it is time for the next phase: improving the incidence of light itself.

The product AntiReflect reduces reflection and consequently improves the incidence of light.

The first growers now have experience with this new solution and they are indeed achieving higher production. Tomato nursery Van Adrichem in The Netherlands achieved a 5% increase in production using AntiReflect in comparison with an untreated compartment in the greenhouse which led to higher fruit weight.

Spreading condensation = light gain
During cold periods, glass is often constantly wet on the inside. This condensation impedes light incidence by 5 to 8%. The solution is simple: AntiCondens. This coating operates as a spreader and creates a finely spread out water film on the glass instead of large drops. Large drops impede the incidence of light, while a water film enables better transmission. The application of AntiCondens this way significantly contributes to a better light transmission during low-light months.

Clean your greenhouse
Sometimes light transmission drops sharply, for example when desert sand lands on the roof. When this happens, it is important to quickly clean the window panes because this truly affects production. The GS-4 glass cleaning agent is the right cleaning product for this job. It effectively removes dirt without harming the glass.

AntiReflect, AntiCondens and proper cleaning form a cohesive package of solutions for improving light incidence. Together they provide for up to 10% more light in the greenhouse. Contact Mardenkro for more information about the light transmission package.

Israel announces creation of global seed company

Two Israeli seed producers, Nirit Seeds and TomaTech, have joined forces to create Israel’s largest vegetable seed company. This synergy will enable unique seed breeding research and development that will accelerate the company’s growth in the international seed markets.

Upon completion of the merger, the company will have more than 80 employees worldwide, including molecular biologists, breeders, agronomists, and others.
The company will improve its breeding activities in Israel, Spain, Mexico and Italy, as well as significantly expand its representation in the Netherlands and North America, with a particular focus on growing vegetables in high-tech greenhouses.

Nirit Seeds is one of the most successful internationally traded tomato and pepper seed producers, investing in the development of revolutionary genetic technologies. TomaTech is one of the leading tomato seed companies in Israel, developing premium varieties, including those resistant to the dangerous Tomato Brown Ruffle Virus (ToBRFV).

The production of crop seeds is one of the most advanced and high-tech sectors in Israel. According to the Seed Department of the Federation of Israel Chambers of Commerce, seed exports currently generate $200 million in annual revenue. There are about 25 large and medium-sized companies in the local industry.

For reference. According to market research, the global vegetable seed industry is valued at $8 billion a year and is growing at a CAGR of 8%.

Karachay-Cherkessia became one of the leaders in the production of greenhouse vegetables at the end of 2021


Greenhouse vegetable production in 2021 reached a record 1.4 million tonnes. According to the Ministry of Agriculture of the Russian Federation, the leaders among the regions in this segment are the Karachay-Cherkess Republic, Lipetsk, Moscow, Kaluga, Volgograd, Novosibirsk, Saratov, Chelyabinsk regions, Krasnodar and Stavropol Territories, the Republics of Bashkortostan and Tatarstan. These regions account for more than 60% of the total production in the country. The intensive development of greenhouse projects in our country helps to provide Russians with fresh vegetables all year round. Last year, the harvest in winter greenhouses updated the 2020 record – more than 1.4 million tons of products were received. Including the production of cucumbers amounted to at least 830 thousand tons, and tomatoes – 590 thousand tons. It is expected that by 2025 the volume of vegetable production in year-round greenhouses will be at least 1.6 million tons of vegetables.
