I saw something pretty cool at Lowe's yesterday for those who want to SCROG but need access to the individual containers that your girls are planted in. It was like those tomato training support rings, but at the top of it was a 2"x2" grid. It was made of a thicker gardening wire and had 4 metal posts that stuck into the soil.
I tried to find a photo of it, but couldn't find the right description to pull one up.
EDIT: Imagine something like this, but with a single metal post where the legs of the stand are:
