You should keep taking the creatine, for one, the creatine attracts water into the musclecell so muscle cell increases in volume. If you stop taking the creatine you will loose size. A other reason, creatine supplementation increases protein syntheses.
Even though you will train a home you will engage in short term power movements, in other words you are using ATP as energy, because creatine increases the ATP in your musclecells, you should keep on taking it.
