Thanks for explaining your way of doing it. I'm inspired to research H2O2, and do some experimenting with some bag seed. That's always fun.
I should add: I don't bother measuring, just a dash of 9% H2O2 in a larger volume of water. It probably ends up @ somewhere around 1-3% H2O2.
I doubt if anything this elementary could be true, and yet not everybody already doing it. But try it out for yourself, and post your results, if they're anything unexpected.
I agree. Since I usually germ in the upper 70's, I should get more males if the theory is true, but instead I usually see a 50:50 M:F ratio.
