You say it came from a bag of decent stuff? There's your problem. Hermi plants are genetically predisposed to become hermi under a certain level of stress; if your plant hermed under a rather low level of stress, you can assume that its offspring will do the same. Take that back a step and assume that a commercial grower is providing adequate conditions for his plants, plants that go hermi are unusually weak genetics in terms of resistance to stress without herming, and any seeds resulting from a hermi pollenation in his garden are therefore suspect. You see that they have performed badly in yours.

There's no reason not to de-seed the finished product and smoke it, just THROW AWAY those seeds!!! If you are too pissed off to de-seed the bud, try cannabutter. Instructions stickied in 'edibles'. But most of us would just prefer to shake out the seeds and smoke it
