Dimmable Switch

As you can see from the photo, you can adjust the light intensity with the dial next to the on/off switch. This is the only low cost LED Grow Light I'm aware of that can set the light intensity.

This allows you to use the GalaxyHydro 300W for your marijuana clones instead of using florescent tubes. Increasing the intensity as your clones are ready for the next stage.

Daisy Chain

The GalaxyHydro 300W can be daisy chained allowing you to expand your indoor garden. All you need to do is plug the power cord from one panel into the next as illustrated in the photo.

As the panel only uses 140 watts you can daisy chain 3 or 4 panels without worrying about overloading your electrical circuit.
