I have been told that you can grow BG in a trap that size, I would build one bigger if I was going to use it as a grow out pen, say 6 feet by 4 feet by 2 feet.

As for the funnel, I use two pieces of netting and just push in an opening and cut off the extra on the outside of the cage, I use zip ties to "Lock in" the funnel's shape. I can also cut off the zip ties and "resize" the funnel any time I want and simply re-zip tie the opening at its new size.
