scrog means screen of green, and is basically where u place a square wire screen over a an area of plants and when the shoots poke through wrap them back under the screen and continue to do this untill screen is covered, then put into 12/12 to flower, end reault screen full of bud

sog means sea of green where u place a large amount of plants in a small area and flower if u can straight from clone or if not after only a few weeks in 18/6 veg . this keeps plants small and provides a little bit of bud on each plant but because u have loads in ya grow room it adds up 2 a nice harvest bth ways are intended to save on space, or if u only have a small cupboard etc, you can keep light down low etc, hope that helps a bit m8
