no you bend it slightly sideways.. so instead of growing up it is on an angle

its called LST - low stress training.. dont bend it any farther than 90 degree MAX.. if you leave it tied at 90 or higher it becomes heavy bondage and it can stress your plant.. just bend it slightly enough so that your secondary growth has better light exposure... your secondary branches will grow up and away from the plant, leaving you with several smaller main colas... it will increase yield just a little , but more importantly you will have more uniform potency.. no trashy little popcorn nugs from the bottom part of the plant

so instead of looking like this : | .. your stem will look more like this: /
you get the idea

as long as its not like this: -- then its cool
