Then vertical for sure........Due to the lack of space I am very limited.
I will be using 18" T8s' in a MASSIVE 6sq./ft. space. lol
The setup below is half the area. I will be removing the right wall opening the unit up into one. (was using two different areas for two grows at once, but found out that I need more space!)
The reflective material is 3M Reflective Adhesive, made to reflect fluorescent light! (Hope it was worth it)
