Tips and ideas

Automation for the greenhouse is of great importance, because thanks to auto devices plants receive the necessary care for them in time. This is a new level of development in the field of agriculture. Control by automatic system will solve many problems and save power. They can be embedded in conventional house greenhouses or country houses.

Automation of greenhouses consists of several systems that can be used in a greenhouse:

ventilation;
watering;
heating;
lighting.

Every opportunity needs more information.

Greenhouse ventilation

Ventilation of the room, maintaining balance with temperature drops play a huge role in the life and growth of plants. You can, of course, open and close the frame yourself. But what if you need to go far or control time for this? In this case, it is better to automate the ventilation.

Such systems can be divided into types according to the principle of their work.

Electric control system of ventilation in the greenhouse. Powered by thermal switch. When heated, the relay is activated and drives the electric fan motor. Convenience is that there are settings for sensitivity to air temperature and system power control. But there are also disadvantages. If the supply of electricity stops for a long time, it can lead to the death of the plants. When disconnecting, you need to use a separate generator, which will require additional investments.

Bimetallic automatic airing. The principle of operation is to heat the plates, which tend to expand under the action of temperature. When heated, they begin to bend, thereby opening the sash in the greenhouse. When the plates are cooled, the opposite effect occurs. But if the frames are heavy, then such a mechanism will not always work.

Hydraulic. The system works according to the simplest laws of physics. The system has a liquid that heats up easily and at the same time enters the brass tube. That, in turn, gradually extends and opens the frame in the greenhouse. In the factory version, the system usually consists of a hydraulic cylinder and a stem pusher. The systems are easy to install and operate, and power is sufficient.

Automatic watering

The next function is automatic watering in the greenhouse. The principle of operation of a purchased and self-made device is generally the same. The main thing is to know that you want from this device and whether you can lay out the entire system on your own and configure it correctly.

Before you buy a finished automatic watering, you need to know:

type of system;
pump power;
Which sensors or valves, taps, nozzles (mechanical or electromagnetic) are used in one system or another?
what accompanying parts need to be purchased;
the complexity of self-assembly and system configuration.

There are adjustable and unregulated droppers in the greenhouse. With adjustable droppers, you can reduce water consumption.

Autonomous irrigation are divided into types:

sprinkling;
drip;
subsurface irrigation.

Sprinkling works on the principle of the soul. Water under pressure is fed into the tubes and is sprayed over the plants with the help of nozzles. You can purchase the system in the store. For all types of irrigation need to know the area for processing, pump power and method of assembly.

When drip irrigation water gets a certain way (depending on what kind of water you make or what system you collect) in the tubes, which are laid along the beds. Further, under pressure, water through special nozzles (sprinklers or droppers) leaves the pipes and enters the beds or into the soil directly to the roots of the plants.

Intra soil is suitable for growing perennial plants and consists of using containers or tubes with holes that are buried in the ground next to the root system of the plant.

Heating and lighting facilities

The next automation system for greenhouses is heating. There are such methods of heating greenhouses:

using solar panels
gas,
using the boiler, etc.

The most profitable at the moment is considered to be ordinary stove heating, the stove itself is being built in the greenhouse vestibule, and the chimney passes through the entire greenhouse or even under the beds.

The lighting automation function is also very important. Cables and wires can be laid across the top of the greenhouse or laid in the soil. It is better to install lamps that do not generate heat. Lamps must be moisture resistant. Simple automatics for greenhouses with their own hands can be installed, this will require a time relay, which is mounted in the circuit for each lighting group. The timer is set on / off time, some lights turn on, others turn off automatically.

Create autowatering with your own hands

Now they are selling various systems of automatic irrigation, but making their own automatic equipment for the greenhouse is available to many. You can make droppers with external nozzles, sprinklers, push-button, tape with built-in droppers in the tube. The principle of operation of the device purchased and made by hand is the same. The main thing is to understand that you want to invest from this device, how much money you are willing to invest, and whether you will be able to set up and configure the system correctly. Therefore, it is important to know how to do automatic watering for the greenhouse with your own hands.

First of all, you need to decide where the water will be supplied from: the well, the tank, the tank or from the water supply pipe. The tank or barrel can be purchased in the store or on the market. The source should be near the place where you place the irrigation system. It is necessary to calculate the area of irrigated soil. Next we go to the store and purchase (preferably with the help of a consultant) a hose or plastic pipes, droppers, tees, a pump, a timer or a controller (if you want the watering to take place at a certain time). It is better to purchase filters for water purification.

Preparation of soil for irrigation, as well as the assembly of the system must be done in advance, before planting seeds. When the first dry days begin, you will not have time to go shopping to find pipes and build a system. Place a tank or barrel near the greenhouse. It is advisable to put the source above ground level by 1 m. Do the trenches (if the pipes will run in the upper layers of the soil). Assemble the pipe system in the greenhouse itself, connecting all the joints according to the scheme. Pipes should run along the entire length of the bed. At the ends of the pipes, install the plugs. Make openings in pipes or hoses with an awl in such a way that the dropper fits into the hole with force.

Connect all tubes to the main tube that is powered by the pump. Arrange the droppers so that they are not too large for one group of plants. Remove all the plugs and make the first start of the system. Check if there is enough pressure, if there is an excess of water flow, if water is flowing from all the droppers. Next, make sure the system works on a timer. Water must be supplied and overlapped at a certain time, otherwise there will be a high consumption of water, and overflow of plants.

Thus, the automation of greenhouses is an integral part of plant care and good harvest. Moreover, automation systems for greenhouse management are available to most summer residents.
