Improvising Orchid pots with deli containers

[HiOrcDen]

So I need to repot several Orchids today. I don't have much time, and do not want to wait for them to arrive from Amazon.

So I'm going to use deli containers. I have two sizes/shapes, for which I will attach pics.

I am wondering, for the taller one, are the dimensions too tall and narrow? If they are, what proportion of the height should I cut off? Or alternatively, could I just put a layer of lava rock/gravel/pumice (if so which would be best) at the bottom, instead of cutting the top? Which would be better.

And as for the shorter deli container, which has the same width, would this work better for a 'creeping', wide spreading plant? (that's my understanding)

And similarly, could I maybe use the taller container unmodified with a narrow, tall growing Orchid?

I should add the containers are more cylindrical / less conical than in the pic!
