there is no stretching, these are some of the bushiest plants I have ever seen, i will post pics soon, no stretching, using 1000 HPS light only a little over 2 1/2 feet above plants... trust me no stretching, very bushy. I will try to get some pics taken to post.... but thank you.... I made that mistake last time, and thanks to an artical on here i realized i wasnt doing it right, so i got a book a good light and hydro system, now I am just way excited. thanks again
