I have 2 ~190w meanwell drivers, with 5 citizen CLU048-1212 cobs on each. Half are 3000kelvin and half are 3500 kelvin. I keep them at about 3/4 power though, I think that's plenty for the area covered by the canopy.
This canopy is wild though. Tons of nodes that are just under the layer of leaves. I'd thin the canopy a bit but I feel like they need all the nutrients they can get that's stored in them,so i just keep tucking leaves back to expose more just-under-canopy buds to the light.
