Okay, think about it in terms of the % of total dry PLANT WEIGHT at harvest that is smokeable. Your electricity, water, CO2, and fertilizer go to putting on bulk. How much of that bulk is just lumber? In SCROG or a long-vegged style, you get a lot of timber. In SOG, it is a higher percent bud mass overall.

Your yield numbers are directly related to nothing more than the watts of light in your flower room and the time your plants spend in there. You don't get 'paid' for plants sitting in veg.

A SOG is like cheating- you get all the exposed canopy area under the lights, without all that wood holding it up. Wood is wasteful of your time and fertilizer. Even fruit farms are going to a style that utilizes closely-spaced dwarf fruit trees that only need about a year or two before they begin to bear fruit, and far less maintenance than their standard-sized counterparts!

If you have enough space to keep a mother and a propagation dome, by all means, do so. The only benefit to long veg (by long I mean more than 2 weeks) is a reduction in the number of plants to give xxx grams at harvest.
