Exactly, its about choice. And its about ruining the gene pool. Reg seed are important for more than just private growing needs. At the minimum, every breeder should provide at least 1/2 of there catalog in both.
I think the only justification for selling only fem seeds would be.. alot of people want them.. if you're not breeding males are a waste of time and money.. I think you should be able to choose whether or not you want fem or regular...
