LST them. Bushmaster is great and i'll be using it in my grow for the first week of flowering (link to journal in sig) but if youre trying to keep a low profile while maximizing yield i'd go with the LST technique. No stress to the plants whatsoever, better and equal light exposure to the whole plant and YOU control the height, instead of depending on a chemical to POSSIBLY do it for you.
yeah i lst but these are unstoppable monsters. they were only 2 full leaf sets with little branches when i flowered. i cant imagine flowering sooner than 3 weeks maybe 2 is fine for me
