What temperature should be in the greenhouse: controller how to open, minimum on the street, greenhouse for seedlings

By maintaining an optimal temperature in the greenhouse can substantially improve crop quality Nature awakens from a sufficient amount of solar energy. Only solar energy has such power that all life on earth reaches out to it. One of the indicators of solar energy is the temperature - air, land, and, of course, the temperature in the greenhouse on the backyard. So what should be the temperature in the greenhouse?The solar energy to regulate mankind has not yet learned, the external temperature is not subject to it, but it is quite possible to regulate it in a closed greenhouse.

optimal temperature in the greenhouse: the allowable difference between winter and summer

to determine the moment of entry and to correctly developThe use of plants is one of the important indicators of the temperature regime - this is the average daily temperature. It is composed of the average value of the air temperature, which is measured at a certain time of the day at regular intervals. In order for plants to develop correctly in the greenhouse, the average daily air temperature should be at least 10 ° C.At this average daily temperature, the soil is heated to the required value for planting the crops in the greenhouse.

Select the temperature for the greenhouse should be depending on the type of cultivated plants

If land plants without taking into account the average daily temperature, the plant will get the stress is long to take root and yield, respectively, will appear after the expected period and the yield will be reduced.

Refrigeration plants require warming the soil just above 10 degrees. And heat-loving plants need to have a ground temperature of at least 15 ° C.It should be borne in mind that the soil warms up more slowly than the air and must pass the time to warm up the soil in the greenhouse. The air temperature of 23 ° C and below disrupts the biochemical processes in the plants, causing unfavorable changes, with a change in temperature directly proportional to the intensity of photosynthesis and plant growth. Yield in this case will be lower than expected.

The air temperature during the day 25-28 oC provides maintenance and activates photosynthesis in plants and it is under this temperature regime that harmonious development of crops takes place. If the temperature is high, above 30 ° C, in plants is inhibited photosynthesis and energy is expended on the breath, the vital activity of cultures suspended to the extent that even the flowers are sterile. With such a temperature regime, it is unlikely that the owner will enjoy the harvest in the future. You can not let things go by themselves, you need to take some actions and maintain the temperature regime in the greenhouse to the extent possible.

temperature can be controlled in a greenhouse in winter successfully applying :

• additional artificial heating at low temperatures;
• Ventilation to maintain a constant temperature;
• Cooling for lowering the temperature;Regulator and control sensor
• .

If you constantly monitor the temperature regime and apply appropriate measures to maintain it, then the future harvest will certainly please with its quantity and quality.

. If the temperature in the greenhouse decreases slightly, it can only be of use to young plants, becauseAt this point, they are beginning to develop a root system. But if the temperature reaches an unacceptable minimum and holds a considerable amount of time, then this can certainly adversely affect the viability of plants in the greenhouse. To prevent this situation, various methods of artificial heating of the greenhouse are used.

heating greenhouses can be implemented in the following ways :

1. air heating and blowing over the whole volume of the greenhouse. Such warming up of air can be carried out by electric heaters with a fan.
2. Blowing the heated air through the pipes that are laid in the soil of the greenhouse.
3. Motion of heated water through pipes that are laid in the soil of the greenhouse, for example, using a pump.
4. Heating greenhouses using the stove, which is heated with wood, coal, gas, fuel oil, and others.
5. use for heating around the precoat layer infrared rays special device.
6. Spreading of decaying organic residues over the area of ​​the greenhouse.

Heating can be organized in a combined way, relying on the possibilities and availability of the implementation. For the timely activation of heating, constant monitoring of the temperature regime is necessary. If necessary, the temperature should be lowered. As

open greenhouse at elevated temperature

for the life of any living organism on land requires clean air. The greenhouse can, in the closed state, overheat or in it there may be an excess of moisture, which inhibits the arrival of fresh air to the plants. What is the recommended temperature?To reduce the high temperature or reduce the greenhouse effect in the greenhouse it is necessary to carry out ventilation. The ventilation of the greenhouse is due to the opening of doors, windows, additional shrouds, which allows not to stand up to air and reduces the increased humidity.

If the greenhouse temperature is too high, then it must be ventilated by opening vents

On winding influenced by the following factors:

• presence, number and location of the vent - air vents are usually located on the side, at the ends, On the roofs;
• The location of the greenhouse itself on the site, i.e. It is necessary to take into account the direction of the winds in the area where the household plot is cultivated, the shading objects or densely planted trees next to the greenhouse.

organize ventilation bytogo by using a fan or by natural ventilation, by opening the respective inlets to a predetermined height or doors. For the correct circulation of air in the greenhouse, you need to monitor to change the opening height of the window in a timely manner, or the windows themselves.

The air exchange process must be arranged around the clock. For its implementation, you can use automatic ventilation systems, whose operation is regulated by sensors, both inside the greenhouse and outside it. Automatic systems can use electrical, hydraulic or bimetallic mechanisms. The venting system can be located anywhere in the greenhouse, usually they are very compact.

controller for greenhouse

not always have summer resident gardeners have the opportunity to control all the internal parameters of the greenhouse. A business owner may not have the possibility of a round-the-clock presence on the site or he will simply be too lazy to get up at night and monitor the state of the greenhouse. And as everybody knows, laziness is the engine of progress or the need to introduce the fruits of progress, because special controllers have long been produced for such purposes.

The controller is usually a small plastic box containing electronic boards. The sensors are connected to the controllers at the input, which generate a signal to activate the corresponding action, and the outputs are connected to the mechanism that performs the required actions.

controller for greenhouses can be purchased from a retailer

action which initiates the controller may be :

• control the air temperature inside and outside the greenhouse;
• Control of soil temperature in the greenhouse( can be reduced);
• Opening, closing of the pans to the required height;
• Running the autopilot;
• Start of heating;
• Lighting control;
• Etc.

Progress does not stand still, and, accordingly, the functionality of the controllers is increased, regulation by means of a relay is very convenient. Controllers can be from the simplest, made independently and, just controlling the temperature of the air for organizing airing, to the most that neither is a minicomputer with Wi-Fi. If the microclimate is properly formed in the greenhouse, the harvest will be rich and quality, and also will please a long time.

All plants react to the temperature individually. On the street or in a greenhouse, for seedlings or an adult plant, the indicators will be different. Self-adjustment is possible. Using the above tips, you can maintain ideal conditions, and plants will be guaranteed protection.
