IS it true that it's better 2 grow with 3 600watt lamps rather then 2 1000watts. I was reading this book and they said the light spread from the 3 600 watts would be more efficient all around then putting 2 1000watts in. What do you guys think?
I think the main factor is With 3 600s u can put them a lot closer to canopy so u get more out of your lights. On the flip side I've heard that you get more canopy penetration with 1000s
