The C18Q is the latest evolution of weather-responsive irrigation systems, designed to deliver smarter, quieter and more flexible automatic watering for greenhouses, grow houses and garden setups.
Using advanced solar-responsive technology, the C18Q automatically adjusts watering levels according to sunlight conditions - delivering more water in sunny weather and less in dull conditions. With a quieter pump, improved drippers, easier mounting options and increased functionality, the Q Series offers a reliable and efficient solution for watering plants with minimal effort.
Ideal for up to 18 x 20 litre pots or 36 x 10 litre pots, the C18Q is perfect for tomato plants, peppers and nursery growing. It is also repairable, upgradeable and patent protected, continuing our commitment to products that are built to last.

Easy control and monitoring
The hand control module features an LCD display and LED indicators for simple operation and easier fault diagnosis. The unit also remembers your selected settings if the hand control is removed.
