We also know that excessive moisture, as well as its lack, will certainly affect the condition of plants, and it will have a negative effect!
Suppose we are watering a tomato garden. Considering the size of the bush, climatic conditions, and other factors, we can calculate the water consumption for each plant. The initial data on water consumption by plants can be found in the specialized literature. Let’s say we calculated that one tomato plant needs 4 liters of water per day. Based on this, water should be supplied to the system for 2 hours every day. Please note that this is a conditional count! Choose a 2×4 tent.
What is the best way for us to proceed?
- The easiest option is to use an alarm clock so as not to forget to turn on and then turn off the water in time. And the most important thing is not to forget to set the alarm!
- A difficult option is to purchase automation! Of course, this will require some costs, but the benefits are obvious.
The ability to accurately dose the amount of water supplied for irrigation
The possibility of fractional watering, that is, if we know that the total watering time should be 2 hours a day, we can water, for example, every 3 hours for 15 minutes! And your plants will receive a precisely defined amount of water per day, but not immediately, but gradually!
The system works without your participation, without days off, holidays, vacations and other breaks.
- The ability to connect a rain sensor that will block the water supply if it rains.
- The ability to turn on irrigation at a convenient time for you, for example, at night, when there is water in the water supply.
Single and multi-channel drip irrigation controllers
The controller is an easily programmable minicomputer that allows you to set the watering program for your plants and control the watering according to your wishes.
There are single and multi-channel controllers. What are their differences and advantages?
- Allows to automate irrigation of one irrigated zone.
- Have a low cost.
- If your site has several irrigated zones, then you need to use several single-channel or one multi-channel controller.
- Multichannel controllers of different types allow you to independently program from 4 to 12 independently working watering programs for each zone separately.
- If you have 4 or more irrigation zones, the relative cost of automating each individual zone is lower than using multiple single-channel controllers.
Water supply requirements for drip irrigation automation
The minimum water pressure at which the solenoid valves were tested is 0.2 atm inlet pressure. Those. the height of the water column must be at least 2 meters.
This is due to the design of the valve. For its reliable closing, at least a small inlet pressure is required. 2.5 – 3 meters is a complete guarantee of closure.
They often encounter such a problem – there is no central water supply on the site, and watering is carried out from a barrel or other container.
If you water in this way, the barrel should be at least 2-2.5 meters high and the filter and valve positioned at ground level.
Valve supply voltage:
- Controllers of the GEVA 75 and Galcon series with a built-in valve are equipped with 9 volt solenoids.
- To power the controller and valves, 1 built-in battery of the “Krona” type is used. The valve is designed in such a way that opening and closing occurs when a small voltage pulse is applied to the solenoid.
- As a result, very large savings in battery power are achieved.
- One battery is sufficient for one year of operation of the controller and valves.
