Kala there are no 'eyes' when you are talking about phals. You have things confused. The only time you can refer to 'eyes' is when you have an orchid that produces pbulbs. For instance cymbidiums or oncidiums. Also the type of reproduction that you are referring to 'cutting in pieces and covering in moss' is cane dendrobiums, not phals at all. You have several different types of orchids all confused into one. Please don't try this with phals, because it won't work. There are several posts with this happening on cut spikes, it is actually very interesting to see how long some peeps have manged to get to. Goodluck!!!

I think what is meant is the nodes on the phal spikes. This is where the keikis come from them and they are sometimes referred to as eyes, just as the nodes that produce growths on a sympodial orchid are.
The link above shows this being done with a phal spike. Really interesting!
