I started growing 2 white widows about 1 month ago, and I am currently growing them under 2 t5 Fluorescents. I like the fact that the t5's are energy and cost efficient, but I want to switch to brighter lights for when I flower them, but I also want to save as much energy and money as possible on my electric bill. How much more energy and money do the HPS or HID, or MH lights cost? Are the costs almost the same? Plus, I don't care about the heat differences.
