I just proved you wrong. I just highlighted where it states it uses heat to create light. COBs produce heat secondarily. HIDs produce heat as part of its standard operation.
Again stop your a idiot all power sources create heat what are people running cobs @ 52 percent efficiency ??? what is the other 48 percent ??? Heat idiot HEAT the more efficient you run a cob the less heat it will produce plain n simple does not mean your going to get better Yields far from it there kiddo
people running cobs to efficient suffer penetration power so the COB law is 52 percent efficient
If you look at vero's the more you drive them as in power the better efficiency you get and better penetration because of power
this is why you do not see huge tree Cob grows because they cannot penetrate you can have all the par you want but if you lose it 12" away then what fucking good is it right ??
Go look at some Cob grows there there sog grows and for good reason not Tree grows like you see with DE units etc
when you see most cob grows what are you really seeing tight compact plants like if they were grown with T5's
No you see at best stretched plants wirey plants then they show buds beside fucking lighters .
you do not see many grows where they use strains that grow Donkey diks but small nug og strain
lets be serious here, Yes every light system has its benefits and negatives find out which ones work for you
With Cobs its never talked about as in what it does but what its capable of
its like saying guess what i am capable of becoming the next president does not mean i am going to be
