ahhhh good ideas, I might try the horizontal approach, at 12-18 inches with my 300w led, I noticed the tips of the leaves were starting to scorch, so I moved it back to about 30 inches, and experimented a little bit, and the tips of the plants leaves always seemed like they were getting scorched, i switch the mainly the T5 and i never had that problem again. It could be that my light is just too focused I was told to get a movable light rail, but I am trying to do this as cheap as possible and T5 is giving good results, but I will try out your suggestion, thank you!
