@Snoopy36You're right, I am going to be completely honest here what Red has said has made the most sense to me so far. I did count you out once I heard that. But I promise you I will do my research and get to the bottom of it and either keep doing what I'm doing or adjust accordingly. I just think you can't expect someone to completely change up their grow space based upon what you gond works best for you. I 100% trust and believe that you are successful and it works for you. But I'm telling you that what I'm doing works for me and several people I know who have disp as well as grow houses. I will take it into consideration and do some research
Red and I have been friends for some time now. He's very good at what he does. I would never say anything that didn't concur with him. But what I'm saying about photoinhibition and PPFD (The density of the photons coming from your light that fall within the PAR range, which aside from UV and IR is all that's ever really needed by the plants) is very real.

"The graph below describes the relationship between light intensity and plant growth. As you can see the lower intensities produce less growth but are also more efficient. A PPFD of 400 achieves over 50% growth potential while a PPFD of 800 improves the growth to about 85% but not doubling it. As the light intensity approaches 1500 the amount of additional growth slows and light intensities above 1500 will begin to harm a plant. A common balance between performance and efficiency is in the 600-900 PPFD range."
PPFD vs. Photosynthesis
PAR value = PPFD
