Water - one of the main sources of life for any living organism.

Plant cultures are no exception in this regard, for which life-giving moisture is the main means. life support.

Therefore, for each greenhouse owner, the question of organizing high-quality irrigation is far from last. There are different ways to irrigate greenhouse plants. Some of them will be discussed below.

Greenhouse watering: options

There are the following methods of watering in a greenhouse: traditional hand or auto... The first requires constant physical effort, while the second needs proper organization, as well as some financial investment to buy materials. But first things first.


This method involves using for watering hand tool and inventory, namely:

  • volumetric tanks equipped with a special watering can;
  • ordinary watering can;
  • buckets.

Using watering cans water pours from above, wetting not only the ground, but also the bushes themselves, therefore this method of irrigation is also called sprinkler irrigation.

Reference: watering is not suitable for every type of plant, since in some cases water, when it gets on the bushes, causes the leaves to curl and appear on them yellowness.

How to water in a greenhouse? Watering with buckets performed under plant roots, while the water spreads along the furrows, which are initially made with a hoe on each side of the row.

In this case, the main thing is not to be mistaken with the amount of water, because due to the fluffy soil, the liquid will absorb quickly, as a result of which it may appear that the plants lack moisture.

Also manual watering plants in greenhouses can be carried out using hose.

In this case, both the use of the sprinkler method and irrigation at the root are possible.

Can be used as a source of liquid supply bulk tankinstalled on a hill and equipped with a crane to which it is connected hose.


For arrangement automatic system Various methods can be used, among which the following are the most common:

  • drip irrigation;
  • sprinkling;
  • underground watering.

The most requested method is drip irrigation, which is easy to operate and suitable for many types of plants.

You can make a do-it-yourself drip irrigation system for greenhouses. It consists of the main conduitproviding water supply from a water supply source. Drip pipes are connected to the water conduit, through which the liquid flows to the irrigated areas.

main feature drip system consists in the fact that water flows precisely to the roots of plants, due to which the leaves and fruits remain dry, which is of great importance for many types of crops.

There is also an automatic micro-drip irrigation system for greenhouses. AquaDusya... You can read more details here.

Sprinkling is a method in which watering is done from above. For this, special irrigation systemsequipped with spray nozzles. The design works by supplying water under high pressure through a hose connected to it, through which the liquid enters the sprayer.

Underground watering can be arranged in several ways:

  • using plastic bottles;
  • through a vertically dug plastic tube;
  • through plastic pipes laid underground.

Methods using a plastic bottle and a plastic tube have a similar principle of operation, in which the water poured into them enters to plant roots.

As for the laying of plastic pipes, this is essentially the same drip irrigation, with the only difference that in this case the pipes are not on the surface, but buried underground.

To prevent the holes in the pipes located underground from clogging, they are put on filters, which can be used as conventional nylon stockings.

Water supply

For timely irrigation of plants, a prudent owner must take care of the availability of permanent water supply... And since most areas of a particular area are experiencing serious problems with the continuous supply of water from centralized systems, the best option in this case would be to install water reservoir, which will allow you to stock up on water in the greenhouse for future use.

Availability capacities in any case necessary for the arrangement drip irrigation system.

How to install an irrigation barrel in a greenhouse? The water tank can be installed both outside and inside the greenhouse. Most often used containers with a volume 150-200 liters... When installing a water tank outside the room, it is usually located on a hill at a distance 1.2-1.5 meters from the ground, not far from the greenhouse itself.

Location reservoir inside the building has some positive features:

  • the temperature of the water in the tank coincides with the temperature in the room (the water for irrigation in the greenhouse must be warm);
  • a reservoir heated during the day will help maintain the temperature in the greenhouse at night and will also serve as a source of supply required humidity.

The disadvantage of this method is that the container installed inside will occupy place in the garden, therefore, this option is more suitable for spacious buildings.

What is humidity control for?

Maintaining humidity in the greenhouse - one of the main points affecting the formation of a favorable microclimate. For most greenhouse plants, the air humidity should be at least 50-70%, and soil - 65-85%.

At the same time, the moisture level for different crops has different parameters, which is the reason for the need artificial moisture creation... Its control is in second place after temperature control.

Attention: with an insufficient level of humidity, conditions are formed that lead to the development of spider mites on some crops.

Plants love not only moist air, but also moist soil, and these two indicators are inextricably linked with each other - what higher humidity air in the greenhouse, the wetter soil.

However, all this is relevant for the daytime, while at night the plants need minimal humidity in the greenhouse. The reason for this is that the air temperature drops at night and excessive humidity will lead to the occurrence of diseases.

Maintenance methods

To maintain the required humidity level in the greenhouse, special measuring devices are used - hygrographs.

If it is not possible to purchase this device, you can use psychrometer, the readings of which during operation are checked against the psychrometric table.

To prevent the formation of excessive moisture, which can occur due to condensation accumulating in the room, the greenhouse must be equipped with good ventilation.

For this, it is recommended to equip the upper part of the structure with ventilation vents during construction.

As a way to deal with condensation, you can cover the beds. plastic wrapwhich will also help retain moisture.

Summing up, we can say that watering method depends on the type of crops grown (the same moment must be taken into account when determining the amount of liquid used for irrigation), the size of the greenhouse, as well as the financial capabilities of the owner of the site.
