Here we go again,

If you place the plant outside the sun the sun is putting out how many trillions of lumens ? Of course it's going to do better, not because it is full spectrum but because of the brightness.

I agree full spectrum does match the sun better than cool white. We both know you don't use cool white in the bloom room. I was talking about veg'ing. You can use a full spectrum or a cool white and the results are going to be pretty much the same because the full spectrum bulbs I've seen are dimmer, so what you lose in cool white to the full spectrum you make p the difference in brightness so it is a draw in that situation.

What gives, I know we are both on the same page, and agree on everything but the way I word it and the way you word just conflicts doesn't it ? :peace:

well during the first stages of life for cannabis like germination, seedlings and vegetation the light spectrum changes for the plant. it enjoys MHL for veg which is more blue spectrum same with florescence. than towards flowering it prefers more of the red spectrum but more lights more growth!
 
more light is more growth and full spectrum is better than 1 spectrum..ive seen better plants outdoors than indoors and ive seen alot indoors..
 
im vegging with a 400 hps and i adding t5s with the blue spectrum when i flower and get em..but from seeing the crystals,color and nodes i would go with dual spectrum..im gonna add warm white and cool white bulbs to the t5 to veg after im done with this grow
 
ny......white widow,the purps and im gonna add some ak47.i got the seeds im just gonna wait till i get some females before i start some more
