Lights at night?

[John]

I have just signed up for Real Time Pricing for my electric meter and want to know if anyone has run their light setup through the night instead of the daytime. On this program, my electric rate will change every hour based on the wholesale electric cost to the utility. Since power costs less at night, I hope to save some money. My thought was to turn the lights on at about 6PM and off at say 6AM. Since the plants are in the basement, they will have low light/darkness during the day. Has anybody tried this?
