I'd like to see someone get a plant to grow horizontaly in a 7ft long space, I mean you would have to support it all the way down, but you could light the both sides of it, from under neith, and from the top, and put a big as hps at the end.... but you would definately have to figure out a way to support the plant, maybe put hooks in the ceiling and tie it to the ceiling, but, man, I think you could get it to grow at a 90 degree angle....
