Help with the AG hood

Hey all. I need some help.
My plant is now over two feet tall and my AG hood wont go any higher. I'm not really sure how I should hang it so I was wondering if anyone had any suggestions? There are steel bars across the top of the grow box so thats what i have to hang from.

im going to drill into my hood, so i can hang it better

word, that sounds like a good idea. For a temporary fix I have S hooks on the rim of the hood and they are strung up with steel wire
