I have heard this SOG kind of confused lately.

A SOG is a continual Harvest each month or 2 weeks. Say as you harvest half the flower room you will have clones already vegged and ready to take the place of harvested ones. It's awsome. When they got me I had 5 months all lined up. Cloning ones, vegging ones. Within 6 months I would of had pounds. All different strains of delight.

Not to be confused with SCOG. Which is screen of green, where you have just a few or a bunch that are trained to grow through a screen to make the canopy all the same height. Mass harvest.
