Can I put them in a glass containter?

[jasonmom]

I have 4 seedling Cattleya I rescued from Lowes. I am planning to put them in a glass container. Plan to put some glass rocks in the bottom. Then have the plants in orchid substrate from Lowes. I figured that way I could see the water in the rocks but make sure it didn't go high enough to get to the bark orchid mix.

Now I'm thinking this won't work. I've done so much reading I think I'm getting myself confused .

Help please.
