im new everyone and one of my main worries apart from smell is electricty now i've read up on a ballast and it seems to me that they not only light, the light they also balance the light for the plants, now im figuring to keep my 400w off the radar couldn't i just light my bulb with copper wire and a battery like the science projects?? i could care less about balancing long as my light work and is not showing up on my elect.bill
