It is indeed. I get quite a lot of my seeds from "hermied" females that a good friend of mine seems to get in his grow fairly often. I don't seem to get the same issue myself so never have any seeds "left over" to play with but get some good things to try from him.

Sidenote: I wouldn't want to pollinate the seeds I get as they aren't very stable by the third generation or so but just to grow out and use for ourselves it works out fine.
