ok, in a hydro grow when you harvest it do you clip the plant at the base of the plant or where the budding ends. i ask this because I heard that hydro plants just grow right back.

I'm speechless, I dont know what to say to that

LOL. Cut it where you like. All plants will get new shoots appearing on the stem if you wait long enough, even in soil. It's just not very cost effective. Best to throw it away. It's okay if you want to experiment with one plant, but I wouldn't bother getting another crop out of it. With practise you might be able to get a good yield, but it still won't be as good had you grown a normal crop.
