Watering plants at the summer cottage is a rather troublesome business. Especially during dry and hot summer.
In hot countries, drip irrigation for greenhouses has long been used as the most convenient way of economical and high-quality irrigation. In our country, this method is practiced relatively recently.
The essence of drip irrigation
Principle of operation drip irrigation is to deliver moisture directly to the roots plants without affecting the stems and leaves. It is known that on a sunny and hot day, drops of water on the leaves form a kind of lens, and the leaves get burned. Drip irrigation in the greenhouse will eliminate these problems.
The greenhouse has a fairly limited space and the soil is quickly depleted. With normal watering, puddles form on the soil surface, and water does not fully flow to the roots of the plants. At the same time, the structure of the soil is also disturbed. When irrigated in small doses, the soil structure remains virtually intact.
The essence of this method is economical water supply to the greenhouse. Using drip irrigation is almost impossible to waste water. This is especially true if the site has a central water supply.
Greenhouse irrigation system options
Water is supplied to plants in small doses and usually such systems are automated... The main elements of such a system are droppers... Drippers are divided into two types: regulating the permeability of water per hour and not having such a function. In addition, there are droppers that allow you to maintain the water pressure regardless of the pressure in the pipeline.
Hoses are also attached to the droppers, which come from the main source of water supply. Typically, this is a plumbing or a large container filled with water.
REFERENCE: Such systems are strong and durable. Their use is usually used in large farms.
A budget option available to every summer resident. The main disadvantage drip tapes this is their fragility, and easy damage by garden pests, but at the same time they are very easy to install.
The structure consists of a water supply hose, all kinds of fasteners and a thin-walled polyethylene tube on which there are holes from which water comes.
They are located at different distances from each other. It can be 20 cm and 100 cm. After the water supply hose is connected to the tape, water begins to flow from these holes.
The plastic bottle method is extremely economicalconsidering that this material is practically free. Anyone can independently build irrigation in the greenhouse with the help of bottles. This does not require special skills.
IMPORTANT: The undoubted plus of this use is that the water in the bottles is heated to the optimum temperature for irrigation.
The disadvantages include the fact that such a method not suitable for large greenhousesthat would be irrational and problematic. And also with such watering, the soil must be light, otherwise the outlet holes in the bottles will quickly become clogged.
This method is also called "oozing hose". It is somewhat similar to the drip tape method. Only in this case, instead of tapes, is taken regular hose, which connects to a filled water barrel or a central water supply. Holes are made in the hose and distributed over the beds in the greenhouse.
REFERENCE: The hose is made of a sufficiently dense material that protects against damage from insects.
Pluses in simplicity and cost-effectiveness of the method... The only downside is the uneven water supply if the hose is connected directly to the water supply.
Some automated kits do the entire process autonomous... The automatic greenhouse irrigation system itself consists of a large container of water and a network of hoses attached to it.
Automation consists in the fact that the structure is equipped with pumps connected to a water supply system or a well. That is, watering in the greenhouse is automatic, carried out without your participation.
Automated systems have a built-in self-cleaning function, as well as various valves and filters. Drip hoses in such designs are rather thin, when folded they become flat, for which they are called "tapes".
Auto-irrigation in the greenhouse can be subsoil and drip. Subsoil watering has the greatest effect as the water flows directly to the roots. The topsoil remains intact and moisture does not evaporate from the soil surface. This method, although very effective, but not many can afford it. Therefore, it is not very popular yet.
Automatic drip irrigation systems can operate with little or no human intervention. They are installed timer and electronic controller, which is configured to automatically fill the container and supply water.
A simple design, which consists in superficial spraying of small water droplets on the beds. At the same time, a large amount of water is divided into small drops and exactly the plant or crop that needs it is irrigated.
Micro-drip irrigation can solve such a problem as watering two adjacent crops that require a different amount of fluid supplied. This becomes possible due to localized wetting of the desired area.
The method as a whole has no drawbacks.

- Special tanks for water storage;
- Water supply or well;
REFERENCE: When filling a barrel or cistern, the water has the ability to warm up to the optimum temperature for watering the plant. Which is very useful for all types of garden crops, since cold tap water can provoke some diseases in plants.
Barrels are used for all types of drip irrigation. From the simple hose method to fully automated systems. Although drip systems are able to perform their function without the use of barrels, warm settled water is more useful for plants than the same water itself, but coming directly.
The stores now have a huge selection of drip systems for every taste and wallet. And it is often difficult to choose the optimal system. When purchasing a drip irrigation system, consider the following:
- If the greenhouse has large area or several of them, it is better automated system can not found. It will provide the state of soil moisture in the best possible way.
- If frequent visits to the summer cottage are impossible or planned vacation, then you should pay attention to the models with built-in timer.
- Also, drip systems have a difference in the estimated area of irrigation. Before going to the store, you need to know exactly the size of the beds in the greenhouse.
- At all budget options include only hoses and connecting mechanisms for connecting to the centralized water supply.
Hot and dry summers, as well as infrequent visits to the country, will cease to be a problem. Drip irrigation for greenhouses is a way to forget about the hassle and difficulties of standard irrigation forever. We hope you now know how to choose a drip irrigation system for your greenhouse.
