I have scrogged Super Critical Auto and had a decent result. At the time I was doing a CFL grow so I wanted to keep the light as close to the tops as possible and maximize the light.CFl's ahve pretty poor light depth penetration and the strain could grow up to 120 cm.
Now with the price of a decent LED in almost everyones price range I don't see the point of scrogging autos.
Instead I favor Dwaring/Stunning method.
To do this you start growing your auto in a smallish pot Iuse 1Lt - 1.5Lt long root pot {ones that are a nice deep length}.
At the first sign of sex transfer into larger pots, I transfer to 8.5Lt pots.
This is a method of dwarfing auto's prescribed by The Joint doctor & Mephisto Genetics to keep plants compact.
I have a journal that show my dwarf plants just click my signature at the bottom of my post.
These are the auto's I dwarved back two Northern Lights {of which the tallest got to 18 inches} & in front are two Autobombs {the shortest of which only got to 12 inches}
