Sides of terrarium covered?

[fluffylily]

Hi everyone. I was wondering if it was a good/bad idea to also put some coco panels on the sides of the terrarium to increase surface area for hanging mounts. I was thinking of only covering 2/3 of the entire side walls so it wouldn't look too cramped and you can still see in from the side as well. Has anyone done this or think it'll be a bad idea? All the light will come from the top canopy since I don't have much natural light in that room. Thanks.
