"Smart" greenhouse, or How to make a greenhouse as autonomous as possible?
To grow vegetables in the zone of risky farming in the open field is, of course, risky. The greenhouse at the site helps minimize these risks. Another thing is that without regular care - first of all, watering and airing - vegetables in a greenhouse will die much faster than in open ground. This feature complicates the cultivation of vegetables in greenhouses by summer residents who can come to the site only on weekends. Does this mean that they better abandon the greenhouse? Not! After all, the greenhouse can be made "smart" - to provide autonomous irrigation and ventilation systems. We will talk about all the advantages of growing vegetables in an "independent" greenhouse in an article.
How does a greenhouse work?
At its core, a greenhouse is a closed room for growing plants with transparent walls and a roof to maximize the "capture" of sunlight. And the principle of her work is very simple.
With the advent of spring, the sun's rays increasingly illuminate our areas and, accordingly, greenhouses. Earth in greenhouses warms up much faster than open ground and air. As a result of heat exchange, warm air also heats the air in the greenhouse. He cannot “break through” the walls and roof of the greenhouse and go outside, therefore, he accumulates in the room, creating the same greenhouse effect. And we have the opportunity to plant heat-loving plants in the greenhouse a month and a half earlier than in open ground.
But that is not all. Proper operation of the greenhouse has a number of advantages. This is at least:
- plant protection from spring and autumn frosts, from any temperature jumps;
- creating an optimal microclimate for plant development;
- in cold regions - growing thermophilic plants;
- extension of the term for harvesting;
- protection of plants and fruits from rains, hail, strong wind;
- if you provide a heating system and additional lighting, then in a greenhouse you can grow plants even in winter.
Humidity and air temperature in the greenhouse
The optimal humidity mode and maintaining the optimal air temperature are the main conditions for the successful cultivation of plants in the greenhouse. If the humidity is too high, this will provoke the development of fungal infections, because of which the plants, and then the fruits, will be affected by diseases. And if the temperature is too high, then the greenhouse plants simply burn out. To maintain optimal humidity and temperature in the greenhouse, it must be regularly ventilated. And with this, many summer residents have a problem.
Not all gardeners live at their dacha all season, and you need to open the windows or doors on time. And if it is hot during the day, and frosts promise at night, then who will open in the morning and close the doors of the greenhouse at dusk?
Today this problem can be easily solved thanks to the modern system of automatic opening and closing of the DusyaSan window leaves, which has already been appreciated by many summer residents. At the same time, even if you do not have a fashionable greenhouse with a dome window, but an ordinary greenhouse with a window, you can install this device on this very window. The effect will be the same!
How does an automatic machine for airing DusyaSan work?
The kit for airing DusyaSan includes very few parts that any summer resident can assemble and install on the window of the greenhouse. It:
- cylinder, its holder, drain and pusher;
- corners of fastening to a frame and a window leaf;
- mounting bracket;
A cylinder filled with special oil responds to temperature readings. At high air temperatures, the oil expands, pushing out the piston, which automatically opens the window. When the air temperature drops, the oil in the cylinder is compressed, the piston returns to its original position, and the window closes.
The automatic ventilation system DusyaSan can be used at temperatures up to +50 ° C. Before installation, you need to make sure that the window of the greenhouse opens without problems, so that no mechanical obstacles prevent the machine from doing its job.
For the winter, the automatic ventilation system DusyaSan needs to be removed from the window of the greenhouse and stored indoors until the next season.
Organization of watering in the greenhouse
The issue of watering is vital for growing vegetables in a greenhouse. If open-ground plants can count on a portion of moisture in the form of precipitation, then protected plants can only rely on watering. In this case, plants in the greenhouse should not be watered with cold water from a well or a well. Therefore, thoughtful gardeners for irrigation install a barrel inside the greenhouse, where the water settles and heats up naturally. Of course, you won’t be able to pour directly from the barrel, at least you need a watering can with a convenient nozzle.
But manual watering is a troublesome business, it requires both time and physical effort. And, again, only summer residents who live permanently in the summer in the summer can water their plants in a timely manner. And, for example, during the fruiting period of cucumbers, these crops need to be watered every day or every other day, otherwise the fruits will become bitter. The "weekend gardeners" have problems with this.
There is a way too! In the greenhouse, you can easily organize drip irrigation. To do this, even before planting, you just need to put hoses with droppers on the ridge system of drip irrigation system "AquaDusya". When planting a plant, a dropper is stuck next to it. As a result, moisture will flow directly under the root of the planted crops, and all weeds in the greenhouse will be left without moisture and will dry out.
Aqua Dusia drip irrigation hoses are connected to a barrel tap. It is enough to open it, as the heated water begins to be addressed, in small portions, flow to each seedling, and in 40-60 minutes it will wet the soil to the optimum depth.
You can open the tap yourself, but you can entrust this simple task to an automatic irrigation system. Moreover, this does not even need electricity. The device works from ordinary finger batteries, which are enough for the entire summer season. The summer resident is only required to set the necessary parameters, indicating on which days and for how long drip irrigation will be carried out, and the AquaDusia smart drip irrigation system will start the process without his participation.
It is also convenient that, unlike some other automatic irrigation systems, it is enough to lift the barrel for AquaDusi from the ground to a height of only 20 cm, putting it, for example, on bricks. Whereas for many other systems of autowatering it is required to raise a barrel by 1.5 m, having built a global "pedestal". But at such a height it does not fit in every greenhouse!
In the fall, the AquaDusia drip irrigation system is washed, dried and cleaned until the next season. And you can not even disassemble it.
Weeding or mulching?
Caring for plants in a greenhouse can be greatly facilitated by abandoning traditional weeding in favor of mulching the soil. To do this, you can use black non-woven material or black thick film. They make round holes for future plants. Then this mulching material is placed on the hoses laid out on the beds from the drip irrigation system. A plant is planted in each hole.
The mulching coating protects against the formation of soil crust and riot of weeds, retains moisture in the soil for a long time. Therefore, one large barrel for drip irrigation is enough for a long time. By the way, you can add liquid fertilizers here, then the automation itself will also feed the plants at the right time.
Dear readers! Growing plants in a greenhouse has many advantages. And all the chores of plant care can be greatly facilitated using automatic ventilation and watering systems. Allow yourself a big harvest with minimal physical effort. Have a nice summer and make the right decisions!
