I cant speak for nothing but the forum cut and as PF said its gone from my garden, not saying the forum cut was bad in anyway except yield and slow vegging but the gg4 totally disables me, forum cut I could function.I don't I culled GSC when I got the GG CUT. For me the GG was better in all areas compared to the Forum. I know a few others that have done the same with GSC CULLED. I also get very baked when I use it and have not built up any tolerance to her yet. I smoke her everyday. I have been grower her starting early 2013
