I know what the books say but in practice most of the RAS facilities that are still around, I have toured, keep it dark, so dark in fact, your eyes have to adjust to the darkness.

I'm aware what they say about day length being important for growth but I think it's minor compared to optimum oxygen, low NH4 and NH3, optimum temps, PH, and feed levels.

I just don't buy into it as being that big of a deal. I know if I had a choice I would take low light levels over the opposite any day.

That said, if you've ever tried to shut out light completely in a building it's a very difficult thing to do. Light gets into a facility very easily.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
