23.07.2021

Summer is in full swing and continues to delight us with fragrant, juicy seasonal vegetables, fruits and berries. One of the favorite seasonal vegetables of Ukrainians is cherry tomatoes. Did you know the following facts about them?

1. 1973 is considered the year of "birth" of cherry tomatoes. Israeli breeders have created this unusual variety in order to slow down the rapid ripening of ordinary tomatoes in hot climates;

2. Not only delicious, but also very useful! Cherry tomatoes have pronounced dietary properties. They strengthen the cardiovascular system, normalize metabolism and are even used to prevent cancer;

3. The name "cherry" - received because of its external resemblance to cherries;

4. Almost all professional seeds are hybrids. They tolerate sudden changes in temperature, climate change, lack of moisture. Therefore, when choosing cherry tomato seeds, hybrids should be preferred (they are marked with the F1 icon on the bag);

5. To date, a lot of selection work has been done, even some cherry tomatoes have a rather unusual taste. Yes, the sweetest cherries can give a taste of strawberries, raspberries, nutmeg and blueberries.

6. Up to 22 tomatoes can grow at once on 1 tassel. And from one bush you can get up to 300-400 fruits of excellent quality. The weight of the tiniest cherry tomatoes does not exceed 10 grams.

7. Cherry - a great product. They are 3-5 times more expensive than ordinary tomatoes, but the demand for them exceeds the supply.

The effect of clear and diffuse glass covering on cucumber fruit yield
09.07.2021

Using proper greenhouse covering materials can provide a more suitable environment for plant growth in Saudi Arabia. The effects of three different greenhouse covering materials, clear glass, polycarbonate and diffuse tempered glass were used to evaluate its effect on cucumber productivity, water, and energy use efficiency.

Results show that either water or light use efficiency was higher in compartments covered with diffused or clear glass than polycarbonate compartments. In consequence, the fruit yield of cucumber plants/m2 was significantly higher (58%) in clear and diffuse glass greenhouses as opposed to polycarbonate greenhouses. In terms of the effect of cultivar or plant density, no significant differences in cucumber yield were found. The use of different covering materials did affect the environmental data of greenhouses. Less light was transmitted through polycarbonate cover than clear or diffuse glass.

The photosynthesis active radiation (PAR) was 996, 1703, 1690 mol/m2/d, while the electricity consumption was 2.97, 3.44, and 2.88 kWh under polycarbonate, clear glass, and diffuse glass, respectively. Meanwhile, diffuse glass compartment revealed 16% lower of water consumption than other covering materials. In this respect, it could be concluded that using diffuse glass, as a greenhouse cover material, has a strong positive influence on crop productivity under Saudi Arabia climate,  write https://www.hortidaily.com

PERSPEKTA uses all these coating materials to build greenhouses of your choice.

We will be happy to put all your ideas into practice!

What to do if there is too much light in the greenhouse?
02.07.2021

There is a lot of direct sunlight in the summer months. If plants are not protected, photosynthesis and other plant growth processes stop. When the temperature of the environment and plant tissues becomes very high, all the water consumed by the plant is used to cool the plant tissue. In this case, the plants do not work to bear fruit, but to survive. As a result, you will not receive a harvest, which means a profit.

To create a comfortable climate that will save your income, a number of systems are used, the main of which is the curtain system. For different types of crops at different stages of the growing season it is necessary to reduce the intensity of sunlight and the heat to which the crops are exposed. This is especially important in nurseries and when planting seedlings.

With the help of curtains you can adjust the lighting, temperature, humidity and save a lot of heat. Special greenhouse fabrics are used, which perform the following functions: reduction of overheating and reduction of heat consumption, light scattering.

The curtain system evenly scatters sunlight on the surface and inside the plants, accelerating their growth and promoting the development of healthy and homogeneous products.

And also creates a favorable shade and allows light to penetrate deep under the entire surface of the plant. As a result, the process of photosynthesis is improved and the yield in the whole greenhouse is increased.

Fogging system for humidifying and cooling greenhouses
25.06.2021

Controlling the microclimate in greenhouses is an important part of efficient production and consistent yields. Together with lighting, temperature, nutrients and CO2, humidity plays a decisive role in creating an ideal and stress-free climate. Especially in hot weather, cooling is very important to maintain the required microclimate and the proper development of plants.

In combination with curtains to reduce the air temperature in summer, we recommend an evaporative cooling and humidification system, also called "fogging" and "fogging systems". In our opinion, this is the most effective system for our regions that exists today. The system cools the temperature inside the greenhouse to 7 ° C.

How it works? Water is supplied to the air in the form of a pressurized mist through special high-pressure nozzles. The water mist immediately evaporates and removes heat energy from the air, so that the air temperature decreases and the humidity increases.

The high pressure mist system helps the plants stay in balance with the water supply of the root system and the rate of evaporation through the leaves - the stomata remain more open. This increases crop productivity and reduces irrigation and energy costs.

By creating the ideal greenhouse climate you can help your plants grow stress-free and produce great yields!

Growing delicious tomatoes with LED lighting
18.06.2021

Getting really tasty vegetables is one of the most important growing goals.

 Research shows that tomatoes grown under LED lighting taste great. Thanks to the higher light intensity, with the help of LEDs, conditions are created to further improve the taste.

The choice of tomato variety plays an important role, but the growing conditions that affect taste and aroma are equally important, since consumers make their choice based on these parameters.

How do you find the right spectrum for additional lighting?

There are several spectra that can have a beneficial effect on the taste of tomatoes. For example, blue light is known to have an interesting effect. Increased blue light levels have been shown to have a positive effect on taste and smell. Another light spectrum is far red, which can enhance the flavor of the fruit. However, distant red can cause undesirable effects such as increased stem length. In doing so, blue light can do the opposite and shorten the length of the stem. By combining blue and far red, you can get the best of both spectra: improved flavor without extra plant pulling.

So, as a result of studies that compared various combinations of spectra, the most delicious tomatoes turned out to be using the standard red, blue and blue spectrum, optimized for tomatoes.

In general, LEDs can provide more hours of illumination and higher light intensity in the greenhouse, as well as help to achieve a higher yield.

Growing on hanging trays
11.06.2021

Different equipment is used to grow different plants with the help of hydroponics in the greenhouse.

The use of hanging trays allows you to create the most comfortable microclimate for plants in the greenhouse. Vegetables are grown on hanging trays: tomatoes, cucumbers, sweet peppers, eggplants, etc., as well as strawberries. This method is most common in Europe, because it uses automated placement and collection.

Suspended trays are deployed individually along the length of the greenhouse using a special molding machine. This is done in order to minimize the number of joints. The minimum quantity or even absence of connecting seams allows to proceed "Not drunk" by plants drainage water without obstacles. In a closed loop system, this water is purified and reused for irrigation. Thus, the cost of water and mineral fertilizers is reduced.

Note that previously the same trays for growing vegetables were placed on stands. Today, steel supports for trays are used mainly for growing gerberas and roses.

Why can't you grow tomatoes and cucumbers together?
28.05.2021

Can crops such as tomatoes and cucumbers be grown together? As a rule, these two crops are not advised to grow side by side, and there are reasons for this. This is due to different crop requirements for humidity, temperature and care, as well as problems with pollination.

Cucumbers love moist air, so water them every other day or every day. And if it is very hot, it will not hurt to moisten not only the plants themselves, but also the paths and walls of the greenhouse. And these vegetables love when they arrange a real bath: for an hour close the doors and windows, water the whole ground and plantings with warm water and create a steam effect. Cucumbers then grow like yeast. Overdried soil delays growth, cucumber gains weight due to lack of moisture and grows bitter, ugly and thick as a barrel. Due to the lack of moisture, female flowers and ovaries turn yellow and fall off prematurely.

Tomatoes, on the other hand, too humid air is useless. They are easier to tolerate heat and lack of moisture in the soil, as well as peppers and eggplants. At high humidity suffer from various fungal and bacterial diseases: gray rot, brown spot, late blight and other unpleasant diseases. Therefore, in warm weather in a greenhouse with tomatoes, it is desirable to leave open a small window, even at night. At high humidity, the tomatoes stick together pollen, and the flowers are not pollinated. The same thing happens when there is no air movement, ie the plants do not sway. Therefore, in the summer in tomato greenhouses, you can periodically arrange drafts, opening in addition to the windows at the ends of the greenhouse and both doors.

Another reason is that tomatoes in greenhouses are pollinated by bumblebees, so if bumblebees start pollinating cucumbers, we get non-standard products that may be unfit for sale.

We hope you found the information useful.

Greenhouse convertible, have you heard of this?
21.05.2021

The convertible greenhouse has been designed for growers who want optimal ventilation and light penetration. And it got such an interesting name thanks to a special roof, which is mounted on an adapted Venlo supporting structure. This gives manufacturers a full range of options for adjusting the climate to the desired level.

From the outside, when the ventilation windows are closed, the convertible greenhouse looks just like the Venlo. However, the difference is easy to spot as soon as the ventilation windows are opened. The aluminum roof can be opened FULLY.

Instead of being ventilated from the side of the ridge, the windows open from hinges on the tray. The main advantage of the convertible greenhouse is that specific plants can be conditioned and hardened by exposing them to external weather conditions. When the windows are opened, the climate in the greenhouse is fully consistent with the external one.

Purple tomatoes are already grown in Ukraine
14.05.2021

Earlier in our news, we wrote about the fashionable purple tomato trend in Europe, which won the hearts of consumers in Australia, Belgium, Denmark, France, Greece and Spain.

And now, soon we can try an amazing novelty! Ukrainian farmers have begun to grow purple tomatoes that are fashionable abroad. Writes about this SEEDS.

The unusual tomatoes will be supplied to domestic supermarkets exclusively by TM "GORDI" from Cherkasy region. The trade mark is the brand of the Uman greenhouse plant, where modern European-style greenhouses are now in operation.

The YOOM tomato is distinguished by its rich purple rind and red, almost crimson flesh due to its high concentration of antioxidants, which give these tomatoes their unusual color and positively influence a number of health problems. In addition, the novelty has a large amount of vitamin C, as well as a high content of magnesium and potassium, which makes it a treasury of vitamins and minerals.

In the process of natural ripening on the plant, the fruits acquire a characteristic color, dense consistency and accumulate sugar.

We are already looking forward to trying the trendy tomato!

Tomberry - the smallest tomatoes in the world
26.04.2021

Tomberry is a unique brand of small tomatoes that was launched into the Australian market and is incredibly popular with consumers. Writes about this HortiDaily.com

Imagine harvesting on a vine with a bunch of tomatoes with over 200 tiny berries waiting to be picked! Tomberry is 100 times smaller than a regular tomato.

Tomberry originates from the Netherlands, but quickly spread to many other European countries such as Poland, Turkey and Spain, and also found its way to North America, Canada, as well as Mexico and Israel.

The tomato is used as a unique new ingredient in 5-star gourmet dishes and in all kinds of hot dishes like Spanish paella, where it not only adds flavor to a textural splash after consumption, but also a splash of color to any dish. It is used in soups, risottos and pasta dishes and is very popular in Mexican cuisine. And already excited not only high-class chefs in Australia, but also moms, dads, gourmets and, more importantly, children.

Would you like to try these mini tomatoes? We are sure that it is very tasty!

Wide-range greenhouses
16.04.2021

There are several types of industrial greenhouses. One of them is wide-span greenhouses.

Structurally, a wide-span greenhouse differs from Venlo in its span width, roof and ventilation. The span can be up to 12 m, while it has one skate for the entire width of the span. A wider span creates more air buffer, resulting in a more pleasant climate. These greenhouses are used for garden centers and other architectural masterpieces.

It is worth noting the main disadvantage of this type - it is much larger and heavier than the Venlo greenhouse.

The advantage of this kind of greenhouse is the minimum of shade. This design offers almost endless possibilities for realizing specific wishes for greater light and air penetration. Ventilation with solid windows ensures maximum fresh air intake. One-way or two-way opening of windows is especially suitable for mosquito nets.

The wide span greenhouse is the ideal solution for many types of crops. Large column spacing provides more space for plants and automation.

If you have any questions, we will be happy to answer them!

How to grow pepper seedlings
09.04.2021

Pepper is a source of vitamins and useful elements. A crispy vegetable with a rich taste and bright colors will perfectly complement your plate. At the same time, pepper is a rather capricious culture. To grow peppers in a seedling way, you have to work a little.

The time of sowing pepper seeds depends on the conditions and place of planting seedlings. In general, we recommend using the following rule: sowing is carried out 60 days before disembarking to a permanent place, if a pick is carried out, and 50 days without it.

The preparation of the correct and high-quality soil is one of the important stages in the cultivation of any crop. It is recommended to sow peppers for seedlings in loose and light soil. You can use ready-made seedling mixes or you can buy them at any garden store.

Usually, seed producers decontaminate them even before the start of sales, therefore, when buying professional seeds, decontamination can be skipped.

Pepper does not tolerate picking well, so it is most convenient to sow directly into separate pots. Place the seed to a depth of 1-2 cm and sprinkle with a layer of soil, press lightly. Then the containers with seeds are moistened and covered with foil or glass. When the seeds begin to hatch, the film must be removed and transferred to a warm and bright room. If necessary, install additional lighting lamps.

Pepper seedlings need a temperature of at least 20 ° C. And for the plants to grow quickly, provide them with 24-25 ° С. But it is worth remembering that growing too fast can weaken the stem and leaves.

Before transplanting seedlings to a permanent place, the plants must be hardened. It usually takes about two weeks to quench. At the time of hardening, the seedlings should be 20–25 cm in height.

On the first day, open the window where the plants are for 1 hour. Increase the duration of the procedure up to 8 hours every day. Immediately before planting, the plants are taken out on the porch, and 1 day before transplanting - overnight, protecting from too cold air. During the period when you transplant seedlings to a permanent place, the average daily air temperature should be 15 ° C.

Well, that's all, the seedlings are ready to be transplanted to a permanent place!

LED lamps in the greenhouse
02.04.2021

Light is the main source of energy for plant growth. We have already said that the main types of lamps that are used for greenhouses are: sodium, LED, metallogenic, fluorescent, incandescent and high pressure mercury lamps. Which one to choose - it all depends on the height of the greenhouse and the type of crop grown.

LED lamps are one of the most common types and the most promising for today, because with an identical amount of light with NLVD, LEDs consume 40-50% less electricity, and their service life is more than 50,000 hours. That's about 15 years of use.

The main advantage of LEDs is their service life and relatively low energy consumption, while their relatively high cost is the main disadvantage.

Therefore, today there is a certain compromise in the use of LEDs, it is expressed in the separation of crops and trends in the use of these lamps.

For lettuce and greens, which require relatively low light levels, many greenhouses are gradually adopting full LED lighting. Green mass has shown the best results for LED lighting applications today.

The use of LEDs for growing flowers is also gaining momentum, especially for roses. European farms are increasingly replacing NLVD with LEDs, selling the first to Poland, Ukraine and other countries where supplementary lighting in greenhouses is not so common

For growing vegetables - a combined lighting system "interlight". The principle of interlighting is to provide two levels of illumination - one on top (classic placement) for supplementary lighting to the tops of plants, so that the plant continues to grow "up towards the sun". The second level of illumination is at the plant roots. It is an excellent alternative to 250W and 400W NLVDs, which generate excessive heat near the root zone and “dead zones” that form between the luminaires.

If you want to grow your products all year round - think over the right lighting system in the greenhouse or contact us for help.

Favorable days for sowing on the lunar calendar
18.03.2021

According to an UNIAN correspondent, in order for plants to sprout strong and healthy, when planting they need to take into account the phase of the Moon. Some days of the lunar cycle are considered unfavorable for working with plants, while others are considered productive.

Planting tomatoes is usually carried out through seedlings - first, the seeds are sown in a box, box or cup and left at home in a warm place. After 2 months, the seedlings are transplanted into a greenhouse or soil in the garden.

Favorable days for sowing seeds for seedlings:

- in March: 4, 7-9, 12-14, 17-25;

- in April: 3, 5, 8, 13-22, 25-28.

Favorable days for planting seedlings in the ground:

- in May: 2, 5-7, 12-17, 19-22, 24-26;

- in June: 2, 3, 7, 8, 15-25, 15-25, 29, 30.

And we have already transplanted tomato and cucumber seedlings to our greenhouse.

 Additionally, heat with warm glass and a heat fan in the evening. Also installed professional LED lamps for lighting in the greenhouse.

We are waiting for the first harvest!

Automatic window opening
12.03.2021

When ordering a winter garden, we always offer our customers a choice of windows with mechanical or automatic opening. Most choose automatic ventilation, for good reason!

 What is automatic opening and how does it work?

Everything is very simple. When the temperature in the greenhouse rises, the piston opens the window, and vice versa - when the temperature drops, it closes. At the heart of the automatic opening is the expansion of liquid or oil when heated. This helps to regulate the temperature and increase air circulation in the greenhouse.

Usually, for winter gardens perform the function of ventilation of the upper windows, installed on one or both sides of the ridge of the roof of the greenhouse, the side windows-Louvre, as well as doors.

Agree, the constant opening of windows manually - it's quite inconvenient, especially when the greenhouse is high. So choose the best solutions together with Perspekta, because we know how to add comfort to your life!
