like they all said,

the problem with hermies (hermaphrodites) is that they produce seeds and yield less bud. Obviously this less than desirable.

most people veg between 4-8 weeks (24/0 light cycle).
then after your plant has gotten big enough swith the light cycle to 12 hours on, 12 hours off (12/12). This period (flowering) usually takes 8-9 weeks. Remember that your plant will probably double in size at least. During the flower phase you want to make sure there are no interuptions in the dark period... this is one of the things that will turn a female plant into a hermie.

No questions here are stupid, if you have anymore ask away, thats what this place is for.

goodluck!
