Gavita Master Controllers Athena Grow an in-line pre-filter with 200Our e series ballasts no longer require a switchboard to be switched on and off and no longer need their own switch to dim or boost them. Now you can just touch a few buttons on your controller to be in complete control of all your connected ballasts at once. Our Master controllers do this, and much more!
