The plants under the reds/blues had a noticble size difference (not a drastic size difference but noticeable),the colors were brought out of the plant a lot faster, and the frost seemed to be the same as the rest of the room. This past run is my heaviest dried weight to date for me. But I have to say there were a few things I did differently than normal (increased co2 levels, added mono colors, added a pk booster to my nutrients, and ran the lights a lot closer to the canopy) with all that combined I can’t say the success was strictly from the reds/blues. But I know one thing for sure, I will keep everything the same from this point forward.
