Flower Power is set in a left facing big corner on the Power Wall. Hard to miss. The crack is varied to small tips to start to good hand. Pull through a small roof 1/2 way up (the crux) to the 2 bolt anchor.

You will need two 60m ropes to do this. We were able to do it with one 70m (be sure to tie a knot in the 70m). Doubles on .5 to 3.5 maybe some extra on the .75. You will need some long runners as well.
Be careful pulling the ropes around the constriction below the anchors. Even with this in mind, I managed to get mine stuck. The second time, I pulled it as far left as I could from the base of the route and got it down.
Very easy to get a rope stuck on this climb. The constricion just below the belay but above the roof is the crux to pulling. Best to walk as far left as possible and give it a good yank. A very good climb though, with a nice sequence through the roof and great jams.
