Dog:
Your uncle sounds like and adventurous fellow... Do you think he'd be willing to try the nightbreak experiments again? I think you would get a lot of mileage out of re-introducing the Red fluoros back into the night cycle, while keeping the 200W of incandescents in place. It would help you to understand the interaction of Red and Far Red during the night cycle.
The main thing you'd have to keep in mind is that (from what Sal says) the Red:Far Red ratio tends to decrease over the flowering cycle (less Red and more Far Red as the plants mature), so if you re-introduce Red fluoros you'd be working the opposite direction. Meaning, if you can convince him to do it, take it nice and easy. The RedInc lights have both Red and Far Red, but more Far Red overall, so you wouldn't need much Red fluoro light to shift the balance to a Red dominant one. Sal said that he uses a final ratio around 1:1.

I guess that's one advantage to my having plants from three different stages of flowering in one space, I get to see the effects of different ratios on the different stages. In fact, I think I might keep that going while I'm experimenting. :-)
