saddlebag - they are easy . You can use pvc pipe and get the mist connectors, or get the flex / mist lines and the mist heads just poke into the line. We used some you brackets that attached to cross beams , ran a solid line down one of the support poles and hook to a water spigot. Really helps in the 100 degree heat. It can get a bit damp so I would not put them on the inside cross beam but on the outside beam , the wind will carry the mist out into the pen or under the cover . We got ours at either Home depot or lowes.
