yeah you can get buds from hermis. it helps to pick off the male parts if you can. my only plant is a hermi and it still looks good. not as nice as it could if it had spent all the time making buds instead of seeds but.. it was still a good learning experience. im now pretty good at this growing thing and should rock out my upcoming second grow.
If you catch it right when it hermis' - like im talking right when your seeing the sacs form go and snip the sacs off with like a tweezer or something you wont get any seeds and still get good quality bud
