You have to or you'll run out of room with all those plants.
lol my avg height is only 3 ft at chop. sometimes a touch more. in stupid tiny buckets. we used to grow rows of plants in five gal pails with no topping and just some lollipopping. i really miss trimming a plant as tall or more than me.
edit : i'm still confused by the 8 node alternate branch thing. i've never seen anything like that at all.
