The only thing I would recommend regarding the time of day would be to avoid using your lights during peak consumption, incorporate having your lights off between the hours of 5pm to 7pm. That will save you some cash.

This does not mean to have your lights out for only 2 hours. Use the recommended photo periods, 12/12, 18/6, & 24/0. Messing around with your photo period will cause your plants stress!!:hippy:
