Dimensions and lighting of greenhouses
Before you start choosing and building a greenhouse, you need to consider some factors, for example, how much space there is in your summer cottage and your height. The minimum height of the structure in the cornice is 1, 6-1, 7 m, and in the ridge - 2, 2-2, 4 m.
It must also be borne in mind that the higher the room, the lower the temperature differences, and therefore the microclimate for plants is more favorable.
As a rule, greenhouses are built 3-4 m long, and rooms up to 5-6 m are much less common. The width of the protected soil depends on how many beds it is planned to place there. For example, if there are two beds 1 m wide in the greenhouse with a passage between them of 45 cm, then the total width of the greenhouse should be at least 2.5 m.
The door width is 0, 7 m, height 1, 7 m. However, for convenience, you can change the settings to apply to a particular person.
Some photophilous plants need additional artificial lighting. These include tomatoes) cucumbers, lettuce, bell peppers, etc.
We recommend using fluorescent lights for the backlight device. In addition to saving energy, they have a number of other positive qualities: they do not radiate heat (which allows them to be placed directly above the plant) and their lighting is as close to natural as possible.
Instead of fluorescent lamps, ultraviolet (photosynthetic) lamps are often used. Such lighting has a beneficial effect on the growth and development of plants, and also destroys most insect pests.
Conventional incandescent lamps are used extremely rarely in greenhouses. They are uneconomical, which leads to excessive costs (payment of electricity), and also emit too much heat.
