dnt cut it, their just fuckin with u cuz ur unsure, i saw ur post about the random plant, kinda cool, id say judging from that pic its around 2 or 3 weeks old, try to dig it up while keeping the majority of the roots intact and put it into a separate pot with good soil. and go from there, as above said knowing the age of ur plant at this point isnt really necessary especially if ur gonna keep it outside, but age helps in letting others know the the situation as u update
