The Harvest-Master Plus does everything the Harvest Master Pro can do with the addition of 8 extra outputs and 8 “linked” inputs for more actions.
Use it to control your nutrients, pH dispensers or other parts of your growing system. The controller can even call you with an alarm condition — overheating, low water/ nutrient levels, or if an intruder is detected.
