I have to go buy wire for my new shop. I've got a pretty good handle on what I need, but I'd like to know which type of wire works best. I just wired up my wife's greenhouse, and I used solid wire, because that's what I had. The solid wire worked well, but it was a little difficult getting all the wire back into the boxes because of stiffness. The greenhouse was a small job. I wondered if the more flexible stranded wire would be better for the shop because it will be a bigger job.
