I've got an 16 day old mystery strain that is surprisingly huge and growing very fast, seems to be an indica and has 9 fingers so far, is it because it's hydro or is it an auto? I'm new to all of this pictures are from 2 days ago
Too early to tell whether it's an auto. If it is, it will flower on its own, probably during its 6th week. If it doesn't flower then, you'll need to switch lights to 12 hrs on, 12 hrs off. In any case, depending on vessel size, autos can get huge in hydroponics.
