I'm not sure what ghost feeding is. Do you mean just put some food in? I thought that the fish would produce the ammonia necessary to offset the bacteria in the One and only.
To my understanding ghost feeding is once you add bacteria to the tank you are then throwing in some food and training the bacteria to eat the food. I.e. they would eat the leftover food. While yes you can cycle a tank this way the only problem I see is then you don't have bacteria trained to eat the fish waste. That is why in my opinion I always cycle the tank with an inexpensive pair of clownfish. Plus the clownfish have a really think mucous coating that makes them more tolerable to non-ideal water parameters.
Just please don't be one of the people that think they can throw in a dead shrimp or fish and cycle the tank that way. Then you are training the bacteria to eat the fish!
P.S. How did you make the lining under your cabinet? It looks nice!
