rather than bending the main stem around the pot like that diagram says, you could also just drill holes all around the lip of your pot, and keep taking the branches and tying them down - check my journal out - its not like super impressive or nothin, but its a simpler way to tie down your babies and maximize your space without doing any type of permanent damage to your plants. the pics i have there are a week old and ive almost doubled the ties since then cuz im flowering and they are hulkin out right now, but youll get the concept.
The only downside is though, you do have to be careful when tying down one branch, and then going to the opposite side to tie down the other. With my banzai, i did that, and pulled my string too tight, and ended up splitting the main stem right down themiddle somethin like 2 inches all the way down the stem. I tied it up though, added some water, n within 3 days it binded itself back together n i took the wrap offa the stem, no problemo.
Good luck with your grow man, i hope it turns out ok!!
