FAQs

What is an automatic irrigation system?

An automatic irrigation system waters your plants at scheduled times, eliminating the need for daily manual watering. Instead of relying on a watering can or hosepipe, the system runs on a schedule you set, ensuring your plants receive water consistently, even when you’re at work or away from home.

What are the benefits of automatic irrigation?

Providing water consistently helps maintain more even soil moisture, reducing the stress caused by overwatering or allowing plants to dry out between watering sessions. 

Consistent irrigation means healthier root development and creates a more stable growing condition.

It’s suitable for growing spaces of all sizes, from compact home irrigation setups for raised beds or planters to larger installations that serve greenhouses, vegetable gardens and allotments.

Which WaterMate irrigation system is right for me?

The best plant watering system depends on the size of your growing space, your water source and how much irrigation coverage you need.

WaterMate Mini is ideal for smaller gardens and compact growing areas, while WaterMate Pro is designed for larger spaces and can be expanded to support up to six irrigation zones.

If you’re unsure which combination of controllers, pump, valves and accessories is right for your setup, you can use the Build Your Own WaterMate guide to compare your options and configure a system that matches your requirements.

Can I install WaterMate myself?

Yes, WaterMate has been designed for easy DIY installation, with step-by-step guidance covering everything from connecting the pump and control unit to installing pipework, drippers and sprayers.

Harvst irrigation systems come with downloadable instruction manuals and dedicated installation guides.

Should I choose a solar or mains-powered system?

The best option depends on where your irrigation system will be installed. Solar-powered systems are ideal for allotments, polytunnels and other locations without mains electricity, while mains-powered systems provide longer watering durations for permanent installations. 

Our Build Your Own WaterMate explains the differences and helps you choose the most suitable configuration.

Does WaterMate Work on allotments?

Yes, WaterMate has been developed to support allotment growing and can operate from water butts, storage tanks or mains water. Solar-powered and 4G connection options make it well-suited to plots without electricity. 

Does WaterMate need Wi-Fi?

No, WaterMate continues to run its programmed watering schedules without a Wi-Fi connection. If Wi-Fi is available, you can monitor your system remotely and update settings through the Harvst app.

The WaterMate FAQs explain how both online and offline operations work.

How much water does WaterMate use?

Water usage varies depending on your irrigation layout, watering schedules and the types of emitters you use.

By delivering water directly to the root zones through drip, soaker or hose, WaterMate helps reduce unnecessary water use compared with manual watering.
