You are very welcome. Yes, I would hate to have to deal with 8' wires. You could actually go another foot or so shorter by simply extending the length to make up for it. Keep the height to a level you can easily reach from the ground. I am a short little person with short little arms. I would go with a 4 foot height because they will still grow at least 5 feet high and possibly higher. Anything much above 5' would require a step stool or small ladder for me. Hope this helps!
