They look pretty good. How are you planning on watering them? I can't remember exactly where I saw them, but some cages specifically for Capsicum were large and included some bees. Another good thing about Agribon is it will keep the ladybugs in and new pests out.
Edit: Here's the reference. I think I saw it online somewhere...
