male flowers found

I left for a few days with the girlfriend in charge, came back, and now I've got a few male flowers on an indoor Indian Haze plant. Three flowers actually opened up already. These plants have been flowering for a month now...

The strange thing was there didn't seem to be any pollen. They just seemed like green flowers that opened up. Anybody out there with any hermi experience? Is it common for male flowers on a hermi plant not to produce any pollen? I'm really hoping I got lucky here...
