Helping strech

I hope thats whats its called when it grow really tall and skinny..
what can you do to make it stronger and thicker?


ive been splinting it(holding it against a piece of wood to hold it up) and blowing it with a fan at night..pretty hard and i made a catcher(what i call it a twist tie that does allow the plant to bend over all the way and snap) to allow me to blow it really hard in hopes of making it stronger....?:confused:

i got this plant from a newbie grower, cause i can hide it and his parents found it and flipped and i explained to his parents (his dad smokes) that this came from some bomb shit and the seed was the sSHIT's and to let me have it. It was grow indoors in a window sill so it stretched REALLY BAD.. NOw its outdoors 10 hours a day and indoors the rest of the time...
