Have you ever seen those clothes racks on wheels? They have 4 verticle poles on wheels, and then like a square made of poles that attaches the to the top of the poles and helps them support weight. You could try and either convert one of those, or try building your own. Like take some 1" PVC pipe and some of the 3-way/cube corner fittings or whatever and have the four verticle poles at whatever height you would hang the stuff from. You could run a couple tight lines across the top that wouldn't block too much light, and then hang strings from those to tie to the buds/branches that are too heavy. That way you could lift them without undoing anything or doing damage.
Hell, you could put the plants on pulleys clipped to the tight strings running across the top. If you have one string coming off of the pulley, and then that one string evenly pulls the plants weight from like 6 or 7 different strings and not have to lift from the plant. That would probably be cool, but too much work and too much risk.
