Irrigatia weather responsive SMART irrigation controllers uniquely use solar power to detect the weather and alter watering according to the conditions and the season &; providing plants with the precise irrigation &; to help them thrive. Easy to install and set up, and once in, the C-24 will water automatically with minimal supervision; ideal for small to medium gardens or allotments and can be used for pots, raised beds, hanging baskets, vegetables and greenhouses. It’s great for tree and shrub establishment too. Unlike conventional timer systems, by watering little and often, the soil stays moist and water does not run off, saving you water. A 200 litre water barrel typically lasts 3 weeks.No mains, wires, or hosepipes needed nor heavy watering cans to lug water around the garden. The kit includes the C24 SMART controller with integrated pump, inlet filter, anti-siphon, water level sensor, 15m tube, 12 drippers, stakes, tees, 3 x AA rechargeable batteries (preinstalled – please remove & charge the batteries externally for 20 to 30 minutes before 1st use as they may be flat).
