mookab, I generally prefer bending to topping because IMO, bending does not slow down the growth as much as topping.
You can bend your plant to fit into the available space....you can bend the main stem over and down, and you can also bend any of the side branches into the areas you need....you can use soft string, I like to loop pantyhose around stem or branch, and then tie the loop to mono fishing line to hold in place and train....pantyhose is excellent for use on stems and branches...it stretches as plant grows....
Good Luck!
