I totally agree!
With a natural mix of 50% either way, I have never planted a batch of seeds where I got all male plants. My Harlequin GDB grow did have 100% females which I was actually disappointed about cause I wanted to use this strain's pollen for some crosses, but in my experience it has never been a deal buster with no females at all.
I can understand why those with a limited indoor grow space would not want to deal with having to sort through male plants, but from a big picture perspective I agree with yout that the genetics of any given strain is much better served if we allow nature to take its course.
Lets not forget that all any grower needs to get started is a single female plant! Cloning is not that difficult and if you end up with a difficult to clone strain, you can always invest in an aerocloner which can deliver positive results in even the most hard to clone situations. As I have mentioned many times in the past... My Blue Cheese strain which many folks have admired and complimented me on all came from a single seed grown female plant. In that case I did get 90% males and at the time, I didn't think ahead far enough about preserving that pollen! Something that I still regret well over a year later.
Had I saved that pollen, I have no doubt that I could have spawed some excellent crosses with some of my other high end strains, not to mention as many Blue Cheese seeds as I would likely ever need.
My advice to anyone bummed about getting some male plants out of their seed purchases is this... Let them grow! Set them up in another area and save the pollen! The best way to combat high seed prices is to GROW YOUR OWN!
