See 'growmarijuana.com" The light is fine. I used a 1000 watt HPS lite w/ lite mover for the entire grow. I regret not having the MH for vegging. Get a MH if you can. Elect. bills depends on the time of year. When it turns cold, people use more shit, same as in the hot of the summer. If you bill jumps up during thoes times, big F deal. But during very nice day,.... it looks suspecious. That's just my opinion. You may be looking at $50 per month more. Love your attitude. The smell? I've got 9 Afghans & 3 Ca. Orange Buds budding, and I LOVE the smell. There is shit on the market for the smell. If you grow only Orange Bud, the odor response is that you use orange oil in you mop water, which is then poured on ant beds, clean house, no ants, wonderful smell! The art of lying is to give a thought prevoking answer. Good luck.
