After a little thought, and help from the woman (aren't women so logical?) I figured out the pipes would definitely go horizontally because you would need to use much less of it. Even though my room is 11 feet wide (and only 7 and a half tall) you can support a good five plants with a single horizontal pipe. I like that idea Blue! I am guessing I want to tie each plant from the left side of it as well as the right side of it, up towards the top of the cola... right? Thanks Blue you da man!
