HID Ballast Wiring
One of the best ways to save a bundle on equipment is to wire up
your own lights from a kit. By buying the parts unassembled, you
can probably construct a light for half of what it costs you at a
hydroponics shop. As well, you can avoid the paranoia involved in
shopping there. But I can understand that many of you might be
reluctant to work with wires and electricity. That is certainly
understandable. But it isn't nearly as difficult as you might think.
