I do the 1 week of veg from clone also, but its entirely possible to grow and flower a plant on 12/12 light alone from seed. I can't see how it would be useful except for the very space limited grows.
great so this does work now for the ones that have done this and "yes it was from seed" do you do normal flower time or just go by how she looks "IE brown to white hair ratio"
you should always go by how they look, times r only rough guides, i think shorter plants tend to finish quicker. my 12-12 plants r all budding and i expect the grow to take around 70 days from seed.
