Not the same as a SCROG, but a SOG and yes it wood work. In SOG set ups, they use up to 4 plants in 1SQF. Just don't veg for too long or they will start to fight each other for space. Flower them at about 6 to 8 inches for good results. Also, some people use those 12 x 12 milk crates and just put 4 plants in each one with a grow bag for the liner.
