ace thanks for the help guys, im getting rid of my tent and turning the small area behind my workshop into a grow, with co2 gen etc, all the plumbing is done but i need to finish the rendering and get it sealed etc. I was thinking about running the pipes all around the room then using the floor as normal, turn the place into a jungle. it surely has to be the most efficient way of using your lighting as you could just hang them like pendulums with stuff growing all around.
