I agree with @BluntZilla, don’t go for the real large holes as they are better suited to support netting rather than a true scrog.
I know as I have the big netting and realised the squares are far too large although I made do for this run.
I find 2-2.5cm sized squares is a good size for ScroGing! but you can use any size ranging in 2-5cm depending on grow space and preference.
Hope this helps! Good luck and happy growing :)
