Irrigation Components We Sell

Our collection brings together the key parts you need to build a dependable watering system. Every component plays a key role in keeping plants hydrated across a wide range of growing spaces.

Here’s what you’ll find in our collection:

  • Pumps

    Our pumps support clear and reliable water movement from your tank or reservoir. 

    Harvst’s range includes a high-volume WaterMate Pro pump with push-on connectors, an inlet filter, and a 3m waterproof cable.

    The Mini 12v pump suits compact setups and connects directly to the Harvst controller.

    A 4m waterproof extension cable is available, although using more than one lowers performance.

  • Pipes

    Harvst’s pipes provide a steady route for water to travel through your beds and containers.

    Our 10m LDPE pipe includes an end plug, a 90° elbow, and a straight joiner. It fits easily with standard Harvst fittings, so you can shape clear and dependable irrigation lines.

  • Solar Panels

    Solar panels power your watering system without relying on mains electricity.

    The 10W solar panel includes a mounting bracket and a 4m cable with a threaded power connector that fits WaterMate units up to v11.

    A 4m solar extension cable is also available if you’d like to place the panel further from the control unit while keeping a secure, waterproof connection.

  • Valves

    Valves help you manage multiple irrigation zones with steady and reliable flow control.

    Our range includes a 3-pin splitter cable for adding extra zones to your WaterMate system and twin latching valves with 1.5m cables that work with WaterMate controllers from v11 upwards.

    You can also order twin valves along with a mounting kit if needed.

  • Sensors

    Our sensors monitor the air condition around your plants and feed real-time data into your irrigation system.

    The wireless humidity sensor measures relative humidity and sends the data to your Harvst control unit or directly to your WiFi network for remote data logging. It has a compact 6cm sq. design, a 25m line-of-sight range, and a rechargeable battery. 

    The temperature sensor is a replacement for any WaterMate version. It comes with approximately 50cm of wire and fits directly into your existing system to maintain accuracy.
