yes there is a possiblity you can end up with a hermie...or even a male...nirvana will dispute this saying it cant be a male (they claimed its not "possible" on their website) but i believe it is possible as fem seeds are just MORE LIKELY to be female...you cant really promise it will be female...so far i havent received a male when i got fem seeds but i did get 1 that hermied a little bit but im sure that was more my error than the plant (happened in my 2nd grow).
