Meet The Refresh from Nuravine
The All-In-One Hydroponic Doser
Hydra allows you to not only monitor pH and nutrient levels in real-time, it enables you to set and optimize levels on the go. With integrated pH, conductivity, and temperature sensors, you’ll be able to constantly monitor the conditions of your reservoir at all times.
Fully equipped with 5 precision pumps, Hydra can instantly add nutrients and correct pH imbalances according to your own settings. Each of the 5 pumps can be fully configured to your own specific needs. You could use 2 pumps for pH up and down plus a three part nutrient line, or control pH levels on one direction and use that extra pump to dose with Cal-Mag!
