I'm wanting to build a 4 or 5 cob light just for veg, I see most peeps using the 5000k version but wouldn't the 6500k be a better spectrum? And maybe a higher bin too?
those charts are pretty small but it looks like the cob is much broader spectrum than a t5.although its tough to compare because the t5 chart is for 2 dif t5 lamps and both lack in the 550 to 650 nm
