A grower that has been doing it for awhile will average one gram per watt. So with you hoping for 120, that doesn't seem too far off base! Im a big user of LED's as well as cfl's. I see you said your plant gets rotated daily. You might want to spend some more time reading about the following; LED's as I've read that its not good to rotate your plants only your light. I know that sounds goofy as I know they have the light movers but in a way it makes sense though as well. I can see the light mover going back and forth but to change the amount of rays those LED's are putting out, well I just don't know! How far do you plan to keep your LED from your canopy while they are in flower?
I've never rotated my plants around only the lights and I don't move the lights often. But your plant looks good so I guess if thats what you've been doing then keep on keeping on! Good luck with it all, take care!!
