My box - too late for LST?

Here's a pic of my box with my one lonely lady. I started with 3 but had two boys =/. So I'm only about a week and a half into 12/12 and she's really starting to take off. I'm concerned that I'm going to run out of height in my box soon. Is it too late for me to start LST?

When i get alot of stretch on a plant like yours i tie wire to the top an pull her over as far as shell go. Usualy about top 5 in is layed over an made to grow horizonal.
If she keeps it up i wrap her around in a circle.

good plan. Thanks!

water her first it bends easyer and be easy on her to itll suck to break off the top half............

You can still LST, just do it a little at a time. bend it over as much as you can comfortably, then wait a couple days and try to pull it farther.
