Unsure How To Flower This Plant, Horizontal, Vertical?

It just grew into a bush, it seems that I monster cropped a few plants. The branches try ans out compete each other for light. Do I spread them out and have a vertical grow, do the same horizontally? I did want it as a mother but it would not bother me to start another one and take this one into flower, it is getting a little big. What do you think? It has about 20 of these branches.

Let her go vertical, its really to late but not impossible to change the method

the deal is the hormones(auxins?) are set and working

the hormones that tell the plant which way is up ..lol

nice too

good luck
