there is nothing wrong with using soil and many prefer it over hydroponics. plants can grow equally well in both soil and a hydroponic system.
this has nothing to do with sog or scrog as they could be done in both soil and hydroponic systems.
dont recomend doing a scrog while they can increase yield it is more appropiate in small gardens or cabs with smaller lights it is definatly not something you would want to do on your first grow and you may not ever want to do one.
sog is much easier it is just basicly growin a plant in soil or hydro wich ever you prefer while you are using clones instead of growing from seed there is a reason your using a clone you will know all plants are female and its already mature and can be flowered while it is still very short.
while it may take you a little while to get good at cloning it isnt that hard to do.
