AgrowTek GC-XO Slave Expansion Controller Nutrient Accessories Run it on low overnightExpand your GrowControlTM System with a GC XO Slave Controller The GrowControlTM GC XO slave adds more outputs to existing GC Pro or GC ProXL series controllers. GC XO controllers have the same construction as GC Pro controllers, but are equipped with only outputs for turning relays on an off. Slave controllers do not have any of their own control functions, they simply turn on and off as required by the "master" controller that they are listening to.
