wow ... this took off into quite a discussion. For me, and really that's just me, this is all a matter of metrics with respect to the plants. measuring time or yield or maturity, or colour, size, stem, root, preflowers, pistils, etc etc. For me, it is so dependent upon the circumstances surrounding any particular effort ..... time and space restrictions, patience restrictions, law enforcement restrictions, the weather, the lights, the water, the soil, the nutes, the air, the the the the the the .... the list is endless. The only thing that matters is what do the plants look like today ..... like fdd said, what about a room with multi-strains, and lights and wattev else variable you want to include? In the end you manage the plant to the circumstances that you have .... expected and sometimes, unexpectedly. grow it. wait till its done. dry it. cure it. smoke it. enjoy it. bake it bake yourself. enjoy yourself.
And now for some bud porn .....
