@Grandaddy013 do you have a pic of the light you built? I always like checking out what others come up with.
@RookieReefer the spectral benefits of adding fluorescent to other type of lighting can be huge. But we have to take adding the cfl’s with a grain of salt. The 50 watts per foot we chase is a target based on hid lighting. As latewood stated, it’s not the same type of light, therefore we have to look at differently. Not that there’s anything wrong with what you’re doing, but 70+ watts per foot is typically too much light. And it certainly doesn’t appear that will be an issue.
You can maximize the output of cfl’s by mounting them horizontally and using a reflector. Then angle them so the majority of light is getting to your canopy, instead of off to the side as pictured.
