As long as the roots are not setting in water, you should be fine. Cache pots are great to display an orchid for a short time, but it is sometimes difficult to grow orchids set inside them since they do not drain and block air movement. Your best bet would be to put your orchids in a pot that allows them to drain freely and lets air get in to the roots since they need to be able to exchange gases - breathe.
