By that I mean that the plant requires a bit of time to fill its canopy. Then the plant begins to flower. So, when considering time and energy per gram of product, the vegetative, pre-flowering growth time must be considered.
Any material harvested that was grown during the vegetative cycle is of secondary value, so as far as the cultivator is concerned, this is a non-productive time period.
