Homebox XL scrog grow

I am about to start a scrog grow in a homebox xl which is almost 4'x4'. I am thinking about stringing weed wacker through pvc for my screen and then hanging it. I am just curious as to what others are doing for a net in a in a homebox or similar tent? I think the pvc will work fine but I want to hear some other ideas you guys might have. Thanks
