Im not really sure what they are, I'm probably just going to wind up buying a new fixture but I don't want to when I have two perfectly good ones. But like I said I'm not sure.
My friend gave me two Halo light fixtures that he had. They seem to be good for my small test grow, just one plant.
The only problem is that there is no simple outlet plug. It has a box on the side of the fixture that connects to the socket. Inside the box are the common black/white/copper...
Looks like a nice setup, I'm working a small grow spot at the moment too, I actually like yours so much I may use the same basic set up. How much do those bulbs cost? And the timer?
