Growee dosing systems
Growee systems read pH, EC and water temperature around the clock and correct the reservoir for you, with control and history in the Growee app over Wi-Fi or LAN. The pH Combo pairs the Hydro Master with the pH Balancer for automatic pH up and down control. The Starter Combo adds automatic dosing for 2 part nutrients, and the Pro Combo doses up to 4 nutrient parts. The Hydromaster, pH Balancer and Nutrient Doser are also sold on their own to expand a system.
Where a doser fits in the system
A doser works at the reservoir, ahead of the irrigation valve and filter. Stable solution in the reservoir means every dripper downstream delivers the same feed, event after event.
Fertigation & Nutrient Dosers FAQ
What does an automatic doser do?
It measures the nutrient solution and adds pH adjuster or nutrients in small amounts until the reading returns to your target.
Which Growee kit should I start with?
The Starter Combo covers pH control and 2 part nutrient dosing. Choose the Pro Combo if your feed program uses up to 4 parts.
Does a doser replace a fertilizer injector?
No. A doser manages a mixed reservoir. An injector adds concentrate directly into a pressurized water line.
