I have not personally run lamps vertically. But I know folks and have seen how it is done. It certainly can grow as well as a horizontal set-up. A fan is always good to have on the grow. Also You'd do well in either a tent or a structure of reflective material that can enclose the light around the plants. I do this with horizontal HID lamps with T5HO side lighting. I cut 4' x 4' sheets of cardboard into 2 x 4 panels and either cover with mylar or paint white.
Welcome to where ever we are.
