So if you now have twice as many plants (w/ the vert grow) do you have half as much lumens going to each plant?FROM MY UNDERSTANDING (AND NOT FACT) :
its not how many lumens per square foot that matters. that factor is irrelevant. its how many lumens get to plants (any plants anywhere, no matter how many plants there are, no matter how many square feet they are spread over)
I see what your saying, the trick is no putting on parameters that don't matter or worse using models of meassurement that don't matter. I used sq feet under the assumption that we (as efficent minded people) would fill as much sq foot w/ plant as we can. I don''t know if you see my area of concern or not, clever it is, and space efficent it is BUT it might not be any more light efficent or at the least SO space efficent that it requires more light. <shrug>generally you put a reflector as close to the plants as you can without burn or bleach (minimizing square feet). you can pull any reflector as far back as you want to cover more square feet at the cost of lumens.
a bigger light will deliver the same light to more square feet (and therefore more lumens to plants assuming there are plants on the square feet) (and im ignoring the issue of bigger lights penetrating further too)
ignoring the inefficiency of the hoods reflector the disadvantage of the hood is that the light travels up to the reflect then back down, therefore travelling further and dissipating over distance. vert just goes from the light to the plant.
I suspect if you could wrap one plant around a cooltube you would have near zero square feet but major intensity of lumens hitting direct on plant. that the cooltube is vert or horizontal would be irrelevant then.
just my 2 cents.
I could be wrong, I am just trying to get it straight before I make a major investment. =)
