Mixing light is fun!
Good questions. And that is exactly the stage of planning I am at. I have a 3x4 area with 7 foot light room. I grow in DWC.
I was thinking something comparable to two platinum 300's
well depending on the space u want to go between the COB's and the canopy it gets pretty easy. thinking about 90 degree reflector, 24 inch space between lamp and canopy gives u a spread of about 20 inch radius per COB.
