OK some of the comments here are kinda funny, but not very helpful so here is a bit of info.
If you just want it short because of space requorements, you can keep the plant under 2' with like 5-15 same size colas if you lst it properly starting at about the 4th or 5th node.
try to bend it at 90 degrees and then when it reaches one endge of the pot, start curling it around to one side and trainignthe tops so theya re all even before flowering and while they are still plaiable. ou can pretty much have buds forming a couple inches off the soil line like that.
