It's chest beating without taking into consideration such factors as hood design,
light received as opposed to some black/white "watts" thingie and botany, the latter being nothing more than having the experience and understanding to balance all botanical factors that go into the equation. Like I said, this is the same crap as grams/watt which is nothing more than a forum, anecdotal pretense. Then you have the baloney that stripping a plant of its leaves somehow results in more yield. It's laughable.
That's what it is, lot's of talk. Grow some dope, or rather grow some leaves, lots of them. That will drive your production, not necessarily high light. High light is meaningless unless you understand hood design and the light saturation point of your plants. Once you've fine tuned your light saturation point, and just stay under it, you're in like Flint.

Same with CO2, it's meaningless unless you can monitor ppm and balance it with all the other factors. There's nothing more refreshing than, uh, fresh air.
