Good trellis idea for the greenhouse or disaster?

With the outer grid supports at the plant perimeter, is the inner grid even needed?

It does help for training purposes & will help hold weight of the branches too.

I think I'll try something like what you have there with my autos in 10 gallon pots. Similar to yours but with the outside loop only. Im mostly just trying to spread out the bud sites as much as possible, I try to end up with just open air space up the middle.

You end up w more bud sites by letting them grow a bit before cleaning out the middles.
I do keep the middle stalk bare and about 2-3 inches up each branch. Clean suckers out too
