Lighting UV/IR switch

[supressed]

Hey guys, I've got a new QB with a switch that turns on both UV and IR at the same time. I understand the emerson effect pretty well as far as photos are concerned, but will IR have any effect at all on an auto, as they don't need to sleep technically? I don't have the option to just turn on my UV and leave IR off, so that being said, what would be the best times and length of times to turn these switches on? Right now I've been budding for about a week. I have begun turning the UV/IR on for an hour or 2 a day at most. Thanks in advance for the help!
