Water is the life-giving force for any organism. Without it, most biochemical processes are not able to proceed, therefore, in the absence of sufficient moisture, plants slow down in growth, or even die. In nature, plants get moisture from rainfall and groundwater. Hothouse crops are isolated from the external environment, so they urgently need additional moisture. This requires humidification systems. How to make them yourself, we will tell further.
Why is humidification in the greenhouse necessary?
- Water-deficient plants suffer from the following problems:
- photosynthesis is disturbed (the higher the humidity, the more open the pores and the better absorption of carbon dioxide occurs, which means that the growth of the plant worsens);
- transpiration is disturbed (water circulation in the plant and its evaporation; the greater the moisture deficit, the more evaporation occurs, and this affects the photosynthesis process);
- the growth rate decreases (the higher the humidity in the greenhouse, the better the mineral substances dissolve in the soil and the faster they get into the plant).
To avoid such problems, it is necessary to maintain the humidity in the greenhouse at the proper level. To do this, it is necessary to equip a humidification system.
Did you know? The hottest and wettest room at Kew Royal Botanic Gardens in London — house of water lily. It is a covered pond in which all kinds of lilies swim.
The effect of the use of humidifiers
Each culture at a certain stage of the growing season needs different parameters of air humidity. In all plants, this indicator is above 60%. The humidification system, whether it is an industrial fogger, or a home-made humidifier, allows you to maintain air humidity at the proper level, and at the same time control the temperature in the greenhouse.
In winter, such a system does not allow dehydration of the plant, and in summer it lowers the temperature and increases humidity, eliminating the formation of condensate.
What does a humidification system consist of?
Among modern humidification systems, there are: direct spraying of water (through nozzles), ultrasonic supply of a vapor-air mixture (formed in an ultrasonic humidifier), evaporation of oversaturated air (adiabatic humidifiers) Each system has its own structure.
If we consider a conventional fogger for industrial greenhouses, then it includes:
- High pressure pump;
- pipeline system;
- connecting elements;
- nozzles.
A conventional sprinkler humidifier consists of:
- engine;
- disk
- water tanks;
- hoses.
How to make a moisturizing system with your own hands?
If you have a small greenhouse, then you can build the simplest sprinkler. Its construction is quite simple.
Tools and materials
To create a product you will need:
- low-power asynchronous motor;
- disk (can be cut from a can);
- any water tank;
- a piece of watering hose;
- awl;
- electric cable, plug (for connecting the engine);
- socket;
- screwdriver;
- bolts
- stripping tool.
System installation
Such a system is assembled simply. A disk with small sides is cut out of the tin can (the sides can be bent after). On the sides, with the help of an awl, many small holes are made. In the center of the disk, another hole is made for attaching to the motor. Through this hole, he will be connected to the rotating shaft of the engine.
Important! It is better to install a humidifier in the center of the greenhouse, then the water will be distributed evenly. If it is not possible to place the device in the center, it can be installed against the wall, but then it is advisable to replace the disk with the holes on the impeller so that the droplets fly apart at a greater distance.
Install the engine in a greenhouse in a convenient location. Near it, one level higher, hang a container of water. Run a hose from it so that its end falls on the disc, but does not touch it, so as not to impede rotation. Water flowing through the hose will fall onto the rotating disc and spray through the holes.
The composition of the humidification system: 1. filter system; 2. high pressure pump unit; 3. programmable controller; 4. humidity sensor; 5. piping, fittings and nozzles.
Without creating a humidification system, it is impossible to grow a decent crop of garden crops in a greenhouse. Even the simplest device will significantly increase the yield and quality of the fruit. In addition, it will save time spent on watering.
