slayah since it was only one plant, i would recomend you do the same thing DojaDave is telling you, the fan is ok, actually necessary and good for the plant to keep it strong, but if the wether is too cold and the fan is giving the plant a very chilly wind, it will get depressed.
Also im telling you, you should start to germinate a couple more seeds now, and start all over again, what u have learend so far!

good luck
