Ok I find your choice of light cycle interesting? Why are you running your lights on that odd cycle? Is it for heat control?

Are you using Mylar or white walls for reflection?

There is no such thing (so to speak) as to much light. It's the heat that causes problem more the lumens. I assume you are using cool tubes or air-cooled hoods?

Are you hanging the lights on each side of the plants?

What temperatures are you talking about?

No I don't think you are wasting your time but I do have more questions.
