lights

You need at least 125 watts per plant to have a decent grow. Don't skip out on lights, they are the most valuable piece of equipment iin growing.

 

I don't know, Indica is the mod that knows electricity. But at the cheap price of electricity in the USA, you shouldn't see the electric bill go up by more than $10 a month either way. There's not enough of a difference between the two for me to worry about. I would rather have one light to worry about than 6 lights and extension cords and splitters, etc.
