SOG is simple: you flower the plants when they are about 12 inches tall. Cut off the lower most branches as they tend to get the longest first. you can also top your 12 inch ladies and create more than one cola... Many small plants flowering at once Creates the "sea of green." Some would say that a perpetual harvest is also a part of SOG. With perpetual harvest, you have plants entering flower right as others are being harvested, this process overlaps and continues indefinitely for a perpetual harvest. you can do a SOG perpetual harvest with the room design you have in mind. You would start with mothers and get as many clones as you can. While those clones are maturing, your mothers are producing more clones for you. It can be done relatively easily. You must understand the basics of cloning and environment control for your plants.
SCROG is simple also. You start with one or two plants and you can low stress train these plants to lay over on their side. They will eventually put off shoots that grow upward from the side of the plant. Once you get shoots coming off, you would then FIM the tops of those shoots to create more nodes (bud sites). FIM is explained by MBLAZE in his tutorial on how to FIM. Just look it up. Eventually you set up a grid of rope or plastic above your plant. The idea is that this grid of rope or plastic will slow the upward growth of the plant and allow you to reposition branchs to unused portions of the grid. when you reposition branches, you expose vegetation below them that will grow up and take that spot. The Purpose behind SCROG is to increase yeild by increasing the size of your canopy. The larger you canopy is, the more branches you will have exposed, pointing upwards and hence, you will have more bud. SCROG takes longer than SOG, but you are guranteed a higher yeild per plant; although, you will also have less plants in a SCROG than you would in an SOG. If I were Someone that wants lots of bud and wants it faster I would go with a SOG.
