The WaterMate Pro handles the watering across a large greenhouse, a polytunnel or a whole allotment. Each zone covers up to 20 square metres.

This is the mains version. A 240V charger keeps the battery topped up all year, so watering carries on reliably through dull weather and winter.

It starts as a two-zone system and takes extra zone kits up to six zones in total. Beds, pots and hanging baskets can each run on their own schedule.

The Pro pump delivers 35psi. That is enough for soaker and porous hose. It will drip-feed up to 120 plants, or more using sprayers.

The temperature sensor adds extra water automatically when the greenhouse gets too hot. Connect it to WiFi to control it from anywhere. Email alerts cover high or low temperature, watering, and an empty tank.
