Have lunch during quarantine in a "separate greenhouse"

Greenhouses are so popular in the Netherlands that they can be found anywhere! For example, a restaurant in Amsterdam has set up small greenhouses to keep visitors at a social distance during quarantine.

It is known that even after the lifting of quarantine around the world, the work of restaurants and bars can be much more difficult than any other business. So, we can get a little inspiration from a vegetarian restaurant on the water, Mediamatic ETEN, in Amsterdam.

In one of the "Serres Séparées" (literally "Individual Greenhouses"), as they call the new glass greenhouses, visitors accommodate two people, but up to a maximum of three.

To keep the restaurant staff at bay, the restaurant uses wooden planks, which are a smart way to serve food and drinks. And waiters wear gloves and plastic face shields to reduce any risk of infection.

The result is a personal meeting and outdoor recreation, which still allows guests to practice social distance.

This practice is still on trial, they only invite friends and family to dinner, and all their bookings are sold out. Until this practice is approved by the authorities, it still gives us a positive outlook on what a food establishment might look like today.

We are once again convinced that greenhouses bring incredible benefits, even in such difficult times! So if you still dream of a "Magic Corner" in your garden - be sure to call us - we will help!

Tomatoes for NASA

This year  scientists from the United States have created a new variety of tomato with an edited genome. It looks like a bunch of grapes. Thanks to this feature, it can be grown not only by farmers but also by residents of megacities.

According to Cold Spring Harbor professor Zach Lippman, the main goal of this new study is to create a wider range of crops that can be grown in urban areas or in other places unsuitable for plant growth.

These new tomatoes have a CRISPR-edited genome.

Mutations in genes have made it possible to obtain plants that slow down their growth earlier than usual, begin to bush heavily, and their fruits are collected in compact clusters, somewhat similar to cherries or grapes. The new variety is precocious - in 40 days the fruit can be eaten.

It is also reported that NASA has managed to show interest in new tomatoes. Mainly due to their compact size and the maximum possible number of fruits per plant.

Would you like to try this variety?

By the way, tomatoes are already growing in our greenhouses, we are waiting for a bountiful harvest!

Follow our news, we collect a lot of interesting things for you!

Propagation area in a greenhouse

When planning to grow plants you always want to make sure that yongplants that you have are healthy and of good quality. So where are you taking those from?

In greenhouses of relatively small area, youngplants are most often grown directly in you greenhouse right before the planting. Literally, in the same place. This allows you to save time without additional hassle.

In greenhouses of a larger area (over 3000 m2) always best to organize a separate production zone. It is called a propagation area. Here young plants have necessary climate and handled the best way when efficiently used all resources.

Propagation area allows to grow youngplants without stopping any process in the main production department. In propagation area you want a separate microclimate with its own lighting and irrigation regimes. Propagation area is equipped with its own technological equipment which is individual for each project and depend on the total area of ​​the greenhouse and crops to be grown.

When we talk about vegetables the temperature is maintained around 24°C during the day. It may differ though depending on the crop variety. Make sure that the temperature regulation is done smoothly in order not to harm young plants.

It is also important to dose CO2 when growing youngplants. The minimum level of CO2 is 450 ppm and maximum is 550 ppm. Make sure you dose clean carbon dioxide that does not contain impurities formed during the combustion of natural gas. Sometimes growers do not dose CO2 as the plants do not have a bulk vegetative mass and do not need an increased amount of it. That happens in less professional farming as well.

Plants’ arrangement in the propagation area should be carried out quickly and in a timely manner in order not to miss the moment of strong compaction and stretching of plants, otherwise in the future that may complicate planting in the main production department.

The advantage of having propagation area is that it can be used later  for growing lettuce, dill, parsley or strawberries in pots.

Consider best option for your own greenhouse depending on the type of greenhouse you have, area available and chosen crop. In case you need any help, Perspekta team has an individual approach to each project and we advise the best option for your greenhouse!

What is important when choosing a film?

Film greenhouses are very popular among greenhouses. They have several advantages and are perfect for starting in the greenhouse business.

 When choosing a film, you should definitely pay attention to its main characteristics, namely:

  • Film parameters: roll width, thickness, length

These parameters are set for the project, it is important to cover the greenhouse with a solid roll.

  • High mechanical characteristics

The film must be resistant to high loads (wind, rain, snow, hail, extremely high temperatures, cables, cables, etc.)

  • Light transmission

The overall light transmittance of a film for a greenhouse is extremely important for photosynthetic active radiation (PAR). The range of the PAR is from 400 to 700 nanometers. The intensities of the wavelengths of these waves (PAR spectrum) directly affect the growth and development of plants.

  • UV resistance, film durability

Choose a film that has UV stabilizers. This is an additive that increases the life of the greenhouse film.

  • Heat effect

It is important not to forget about the special properties of the film, which block infrared radiation and help to achieve a controlled temperature in the greenhouse, providing insulation of plants and minimize the operation of heaters at night.

  • Availability of necessary additives

Manufacturers use the best technology in order to create a high-quality greenhouse film that will create a controlled and uniform microclimate in the greenhouse regarding the quality of light, temperature and humidity, regardless of the climate outside the greenhouse. To do this, you can choose additional additives: anti-condensation, anti-fog, anti-virus, anti-dust.

And if you still doubt which film to choose - call us! We will help you save time and effort, advise what is best for you!

Bumblebees in greenhouses

Large greenhouse farms strive to be as efficient as possible and get as many kilograms of production as possible. Without full-fledged quality pollination, this is impossible to achieve. There are many factors in greenhouses that can negatively affect the pollination process of various crops.
 Therefore, the use of incredibly beautiful insects - bumblebees - has become an integral part of this process in greenhouses.
To achieve high results, optimal conditions are needed that promote both plant vegetation processes and high activity of bumblebees.

In Ukraine are already special farms for breeding bumblebees. As its founders explain, bumblebees cause pollination in greenhouses much better than bees. A bumblebee flies "to work" already at a temperature of 7-8 ° C, while a bee only at 12 ° C, and, unlike a bee, also works in cloudy weather. But there is no alternative to bumblebee on tomato: the flower of this plant does not accumulate nectar, therefore, it is not at all interesting for a bee. On average, greenhouses need 6 hives with bumblebees per hectare, for starters - at least 3-4.

Not everyone knows that there is a problem in many film greenhouses - often insects behave disoriented. This is because in such greenhouses there is a blocking of the UV spectrum (blue spectrum) in the film to a wavelength of 380-390 nm. To solve this problem, manufacturers offer new types of films without UV blocking, which allow the blue spectrum of light, which bumblebees need for orientation, to pass through.
Today, for the natural pollination of many crops in industrial greenhouses can not do without these insects. It should be noted that due to effective pollination, bumblebees can increase productivity, for example, tomatoes - by 25-30%. And in film greenhouses, bumblebees can be more effective than bees because they continue to work even in low light conditions and at more extreme temperatures.
Did you know that bumblebees do so much good? Follow our news, we collect the most interesting facts for you!
