'If I were you'
-Since this is your first run with these strains in SCrog, Id limit that area to two plants. You dont know how they will stretch and react, So I would flower right when it hits the screen, and train during the first weeks of the stretch. This way, you're sure to not run outta room.
-Try to go for 4" squares if you can. I tried 2" before, and by the time a top would grow thru and was long enough to be bent to the next hole, the square was too small to make the bend. (hope that makes sense)
-Have one in the top right corner, and train it straight across to the left.
-Have the other in the bottom left corner, and train it straight across to the right.
1000w for veg and flower...these have potential to be monsters!
