Piece of heaven

Constructions - arched and pyramidal, monocular and double-sided, delivered to the wall, temporary, movable, inspection or nursery. Cover - film, glass, poly-carbonate, etc. There are winter gardens, orange trees. Greenhouse is a matter of taste, everyone is guided by his own judgment. You have to perform the function for which it is intended.

It is better to orientate the greenhouse - on a south-south slope to the north, so that it is best lit by the morning and evening sun, and at noon it will be easier to darken.

If the greenhouse is delivered to the wall it is best to orient on the east or south-eastern side. The wall at least one third increases the radiation in the greenhouse - the south side - will not prevent the overheating greenhouse will need to be protected from the sun.

Climate
Ventilation
Ventilation is a crucial part of keeping your plants healthy and cooling down your greenhouse. Fresh moving air also helps cut down on pests and diseases. You can control ventilation with automated solar-powered vent openers and/or exhaust fans. A moderately warm and humid climate keeps the interior intact. unexpectedly lit up the sun, quickly and broadly open the roof windows, with slight heating only a little open, and when cooled-closed. Door in the greenhouse, like the name, is intended to enter. The air coming out from the outside is much colder than the room, which makes the earth slip through, without mixing it with the heat and creating a great temperature difference. This is a dysentery, a stress that can precipitate. Ventilation requires good large sunshades or sunroofs. Ventilation should be carried out in drafts: the hot air rises to the top, mixing with the patenting field air and exchanging moisture and heat with it.
Moistening
Sudden humidity, which means a change in the temperature of the soil, yet changing the pH and chemical composition, is a plant stress. Therefore, it is not recommended to water some hot. Water droplets on the leaves interfere with the natural evaporation process and may cause burns. And excessive irrigation is the destruction of soil structure, the leaching of melting soluble nutrients into the subsoil. Of course, water is essential for the vital activity of the plant - it is the only way of transferring nutrients from roses to leaves, and water evaporation prevents the leaves from overheating.
By automating moistening, the task remains - occasionally refilling the water tank. You can take care of the preservation of moisture in the soil - mulch it in a 3-5 cm layer. Take care of moisture preservation in the air - do not do drafts!

Temperature maintenance
The sun's neck in heaven around the clock. The heat of the sun is absorbed by the soil, especially if it is black and uncounted. Subsequently, the heat of the soil is transferred to the air, which, as it moves upwards, circulates inside the greenhouse. As the leaf of the plant grows, the earth is getting more and more heated and less heated - it happens at a time when heat is not so short (in June-July).
Heat can be controlled by thermal screens. These are black sheets / plates, plastic or mere black film. Quickly sunshine transmits heat to the air. Set up so that they maximize the sunlight, especially the eastern, illuminated area. It is possible not only to lie on the surface of the soil, but also to set it upright or sloping (for example, near the western and northern walls - additional heat collection!). The steeper the angle of the rays, the stronger the fog.
Where there is a need to heat the soil, pour it with dark materials. Can! Not badly protected by stones and concrete. It is suitable for concrete walls and floors, to put "paving" on the walls. The Scandinavians have noticed that the most effective floor stones are 4-5cm in diameter. They are able to completely heat up, and then give away all the heat supplies. However, it's tricky. To completely eliminate the cold of the night, every square meter of glass requires half a cubic meter of stone or brick.
The simple way - to give away less heat is a double layer of greenhouse. Air gap reduces heat loss by double. And windy and rainy weather - fourfold. The inner layer of the dagger does not fade and is not covered with wind. Wind, among other things, increases the heat release by 4-5, and the strong wind - 8-10 times!
The best heat is protected by water. Many people successfully use plain water for this purpose by installing solid batteries in water-filled plastic containers. The water heat demand is twice that of sand or gravel, and even metal. One liter of water accumulates as much heat as 3,25 m 3 of air! In other words, if the sun heats 100 liters of water to 20 degrees, this heat will suffice to warm up to 650 cubic meters of air ten degrees.

Lighting
The solar spectrum has three parts: 1. Short-wave radiation - X-rays and short-wave ultraviolet rays; 2. Ultraviolet and visible spectrum of long-wavelength and medium wavelengths; 3.Infrared (thermal) rays.
And a little more
Soil is almost exclusively bio humus and compost, with a small amount of impurities in the earth. It has a lot of earthworms. Additionally covered with 5-10 cm layer of semi-permeable organic matter. Such soil does not require additional mineral nutrition, nor does it require purging.
Soil fertilization is carried out by earthworms, so there is no need to supplement fertilizer with mineral salts. It is true that a couple of times during the summer, the water can be watered with a very weak solution of complex fertilizers with trace elements (0,1 g / l). When plants grow at their optimum temperature and at optimum air humidity. They are strong, resistant to diseases and pests, do not need any insecticides.
Watered under the roots, water should not be placed on plant stems and leaves. It is recommended to moisten the soil to a depth of 20-30 cm. It is advisable to water the warm, settled, 18/22 C, while in cold, overcast days, especially after cold nights, - (25-30 C) water. Sprinkle early in the morning until 12pm. Additionally, at 16/7 o'clock in the evening, in order to require a beggar. With over 80% moisture, pollen soap does not occur pollination. When too hot (more than 40 degrees C) plants begin to grow, and then they die.
