I was forced to net because a deer went ape s#^% on my reaper, brown moruga, and pink tiger plants. Neighbor kept feeding deer and then took a vacation, so deer got hungry without neighbor there and went after my plants.
Long story short, I netted the plants because I didn't know what else to do to stop it from happening. One month later, no more deer issues and an abundance of peppers. Nature will always find a way though - instead of making the plants bushy it looks like they are just sending branches out of the quarter-sized holes naturally found in the netting.
