you WILL, on occasion get a straight MAKE plant from feminized seeds. not all the time, but it does happen. maybe 1 or 2 in 100. we had a whole back of purple kush feminized that we grew out just old enough to get them to force preflower specifically to get a male plant to make regular seeds. thats why the so-called " elite strains (i.e. clone only)" dont last very long. if someone gets ahold of them and knows what they are doing, its fairly easy to make them seed grown in no time.
