Hi, Pan.
I just did my
first low stress training (forum link below because in-text link does not seem to be working).

This is my first indoor grow, so I decided to use bend, break and tie techniques only. I did no topping or anything invasive except for removal of small branches late in veg cycle.
I assumed an indoor grow would stunt the stalk growth by comparison to my outdoor plants, so I did very basic tie offs to promote even light penetration and, thus, competition among the branches for being the main cola. I used wooden stakes and LOOSE twist ties to guide the main stalk into a horizontal grow pattern: "side grow"
It worked well considering my limited grow space and low-budget light system. You can see in the linked pics that I simply trained the plant to grow horizontally for about a month during veg cycle with a fan to increase strengths in branches so they could support the buds. They have fattened considerably since the original post.
