ive seen worse...but if that does happen to work out for u without any infestation of fungas or bugs and that one cup makes a healthy plant your gonna be really dissapointed if its a female..in otherwords always plant more then you need expect them to outgrow any grow area that small and hope for the best also that fan blowing directly at them might shock them more then help them for that small of a space everytime u open it up to see them they should get enough air circulation ..good luck
