its all a guessing came look at Dutch Passion, 'what makes feminized seeds' to get a better understanding of how to get the most females. every company gets seeds mixed up or seeds fall on the floor when this happens the just scoop em up and put em in a box when the box gets full, the package it up and sell them as mixed. So you get be getting a companies best strains for little to nothing of what they regularly cost. I always like getting mixes whenever I can.
