here's the link about s/h. S/H: A Repotting Pictorial - Orchid Article Library
Another thing, side holes is important when flushing the LECA atleast once a month to inhibit salt build up in your LECA.
It literally cannot be overwatered, and flushing the pot frequently eliminates plant waste products and returns the reservoir chemistry to its "target" values, so is an advantage. At a bare minimum, try to water before the pot dies out.
I hope this helps...
