Watering Timer & Irrigation Controller Buyer Guide for Wholesale Buyers

Spring sowing and summer growth, watering is the most time-consuming task in garden maintenance. Watering by hand every day is not only time-consuming and laborious, but also troublesome for neighbors and friends to help when going out. Sometimes, a reliable watering timer and irrigation controller can enable the garden to achieve "automatic water drinking", making flower and grass cultivation much easier and less strenuous.

Why Customers Like Timers?

1. Always forget to water

When your customers are busy with work, they tend to forget some things. The timer is like a considerate butler. When the time comes, it automatically turns on the faucet. Even the most forgetful person doesn't have to worry about the flowers and plants running out of water to drink.

2. No One Takes Care of Plants during Business Trips or Travels

When your customers are not at home, flowers and plants will "get thirsty". With a timer, they don't have to worry even if they go on a long trip for ten days or even half a month. Moreover, for plants that are sensitive to water, such as orchids and succulents, it is even more necessary to precisely control the amount of water given each time.

3. Uneven watering is prone to waste

Manual watering may not be thorough enough or may be excessive. The timer can precisely control the time and amount of watering, not only saving water resources but also preventing root rot of flowers and plants caused by water accumulation at the roots.

How to Select the Core Parameters of the Watering Timer for Your Customers

1. How Many Water Flows Should be Controlled?

Single-channel timer: Only one water pipe is connected, suitable for balcony users, it can control an entire row of flower POTS.

Multi-channel timer: It can manage multiple areas simultaneously, including the lawn in the front yard and the vegetable garden in the back yard.

Large controller: With more than 4 water flows, it is suitable for villa gardens and commercial greening.

2. How Long Can It Be Booked?

The shortest time interval: Some timers can be set to water quickly within one minute, which is more suitable for spraying moisture during the seedling raising period in river-related areas.

The longest time interval: A seven-day cycle can be set, which can meet the personalized needs of different plants.

How many times a day: The timer should support at least three to four watering times a day.

3. Waterproof Capability

The timer is exposed to wind and rain outdoors every day. It is very important to do a good job of waterproofing.

IP54: Basically rainproof, no problem when placed under the eaves.

IP65: Just place it outdoors and you won't be afraid of heavy rain.

IP68: It can be used in water and is the preferred choice for extreme environments.

4. Power Supply Mode

Battery power supply: Replacing batteries is quite convenient. Two batteries can last for a year, making them suitable for courtyards or balconies without power sources.

Solar energy: Suitable for areas with abundant sunlight, zero electricity charges, environmentally friendly and worry-free.

Power supply type: Connect to the socket and never cut off the power, but it requires pulling wires and a fixed installation.

How to Choose Among Mechanical, Electronic and Smart Models?

Mechanical timer: This model is also known as the knob type. Just turn the button and it starts timing. It is simple and durable, and can be easily operated by both the elderly and children. However, the accuracy of this model is relatively low, with a minimum timing of only fifteen minutes. Moreover, it cannot set complex cycles and is only suitable for simple scenarios where water is applied at a fixed time every day.

Electronic timer: This one can be accurate to the minute and can set different watering plans for seven days a week. Not only is the price moderate, but it also has rich functions, making it the king of cost performance.

Intelligent controller: This model can be remotely controlled via a mobile phone. When users are out, they can water the flowers and plants at home. It is equipped with a rain sensor that automatically stops watering on rainy days and a soil moisture sensor that automatically waters when the soil is dry, achieving smart irrigation. The only drawback is that its unit price is relatively high.

For higher-level irrigation accuracy, many professional users also combine smart irrigation controllers with soil moisture monitoring devices, which help determine when and how much water is actually needed.

Tips for Installation and Use

Installation location: The timer should be installed in a cool place to avoid direct sunlight on the LED screen. The position should be 10 to 20 centimeters higher than the faucet to prevent rainwater from flowing back and causing a short circuit.

First use: Manually test whether each zone can release water normally, starting with a short period of time and a small amount of water. Observe the reaction of the plants and then make adjustments.

Winter maintenance: Before winter sets in, users should remember to remove the timer and drain the remaining water in the pipes to prevent them from cracking due to freezing. If it is a battery model, they should remember to remove the battery to prevent battery leakage from corroding the circuit board.

Daily maintenance: The filter screen at the water inlet needs to be cleaned every month to prevent impurities from clogging the solenoid valve. During the rainy season, it is necessary to check whether the rain sensor is sensitive to avoid overwatering.

Sourcing Suggestions for Different Scenarios

Balcony potted plants: It is recommended to use a single-channel electronic timer. It is best to have a 2-liter spray bottle. This can basically achieve precise water control and does not take up space.

Family courtyard: It is recommended to use a dual-channel smart controller. Users can also equip it with a 5-liter metal spray bottle. In this way, both the front lawn and the back garden can be covered.

Commercial greening is often large in area and rich in plants, requiring a systematic irrigation plan. It is recommended to be equipped with professional irrigation controllers.
