Product Description
The WaterMate Pro automatic watering system is our high power, high capacity system for large greenhouses and polytunnels up to 12’ x 18’, or 40 sq m. It can also be used for grow-houses, cold frames or even outdoor pots, veg plots and allotments (where cover can be provided for control unit)
Everything you need included!
- Powered off 240V mains
- More water on hot, sunny days. Less water when it’s cool or overcast
- Dual watering zones for versatility and extra capacity
- Pump system which can run from a water butt or garden hose (if pump option purchased)
- WiFi enabled (will run without internet too)

Everything you need included!
The Harvst WaterMate Pro allows you to water across two zones for precise control, reduced water consumption and healthier plants. The Pro includes everything you need for watering medium to large (up to 40m²):
- Greenhouses
- Polytunnels
- Garden beds
- Allotments
- Plant pots (including hanging pots, no more water down your sleeves!)
- Set timers to deliver regular and specific amounts of water when you want and for complete peace of mind program the temperature sensor to automatically trigger extra watering when it gets too hot. And, never need to replace a tap timer battery again with the choice of either mains or solar power.
Our Pro pump is capable of delivering 35psi which means you can use soaker / porous hose. The Pro is the most powerful system on the market allowing you to drip water up to 120 individual plants (even more with sprayers)!
WiFi enabled (will run without internet too) so you can remotely control and monitor your system and even receive email alerts for high/low temperature, when watering, or if your tank is empty*.
WaterMate is designed and built by Harvst, in the UK.
Use for: reducing time spent watering, consistent watering, healthier plants, larger yields, going away on holiday, peace of mind, reducing water consumption, preventing disease.
*Must be connected to home WiFi for alerts.
Why choose solar power?
If you don’t have mains electricity in your greenhouse or polytunnel, you can still have powerful automatic watering. The battery is charged by a small solar panel which should be mounted outside to catch the most sun.
Up to 10 minutes of watering time is possible per day in the summer (5 minutes most at one time) and can deliver up to 120L of water.
Supplied with 3m of cable, extensions available.
Self watering, so you don’t have to.
Harvst automatic greenhouse watering system takes care of the watering while you are away, and also provides a regular watering regime which helps many plants grow better.
Why choose pump watering?
You can water your greenhouse or polytunnel automatically even if it’s nowhere near a tap; all you need is a water tank nearby. The powerful pump will deliver up to 17 litres/min at 35psi (more than mains water pressure). Choose the pump model for a pressurised, high flow rate off-grid system which can run from a water butt or tank.
Why choose hose watering?
If you have a water tap in or near your greenhouse or polytunnel, you can connect it directly to the dual zone water valve and leave the pump out. If you have mains pressure water at your greenhouse, choose the garden hose mode.
Dual zone watering helps maximise your garden’s productivity.
WaterMate supports two independent watering zones, using an electric water valve. Each can be controlled using a completely different program, and different sensor inputs. Or, use the two zones to cover a larger area with the one pump.
You could set one zone up for misting/spraying (great for seedlings or salads) and the other zone for drippers (great for plants like tomatoes).
Versatile, flexible, powerful.
Peace of mind, productive growing, and less time spent watering.
Regular irrigation with consistent amounts of water has several benefits compared to relying solely on rain or hand watering. Here are some advantages of regular irrigation:
Precision and Control:
Consistent irrigation allows you to control the amount of water your plants receive, ensuring they get the right amount to thrive. This control is essential for different plant types and growth stages.
Water Efficiency:
WaterMate is designed to be used with a variety of fitting including drippers to minimise water wastage by targeting the root zone of plants directly. This reduces the risk of overwatering or underwatering, which is common with hand watering.
Plant Health:
Regular and consistent irrigation helps maintain consistent soil moisture levels, which is crucial for plant health. It minimises stress on plants and reduces the risk of drought-related damage.
Time Savings:
WaterMate saves you time compared to hand watering. You don’t need to be present for every watering session.
Disease Prevention:
Watering at ground level with irrigation systems helps keep foliage dry, reducing the risk of fungal diseases that thrive in wet conditions, such as powdery mildew or leaf spot.
Convenience:
Regular irrigation can be set on a schedule, ensuring that your plants receive water even if you’re away from home or have a busy schedule. This is not as convenient with hand watering or relying on rain.
Improved Root Development:
Consistent irrigation encourages plants to develop deeper root systems, as they are less likely to be stressed by fluctuating soil moisture levels.
Yield and Growth:
For agricultural or garden crops, regular irrigation can lead to higher yields and faster growth because the plants have a stable and reliable water source.
Adaptation to Specific Plant Needs:
Different plants have different water requirements. With irrigation, you can tailor the watering schedule to the specific needs of each plant variety in your garden or landscape.
Manage and monitor from anywhere with the Harvst app!
Settings are managed directly on the system using any phone, tablet, or laptop. No app needed, no registration required. Harvst do however have a companion app, which brings the following handy benefits:
– Alerts when you need to fill your water tank (pumped version)
– Waters more when it’s hot and sunny, and less when it’s cool and overcast: healthier plants, and saves you water.
– Data logging of growing conditions in the system
– Remotely monitor watering and temperature
