I've had 4 Dutch Passion feminized strains and 3 of them hermied, I find it hard to believe that a top shelf breeder like Dutch Passion puts out seed batches like that all the time. Barney's Red Diesel was just another world of hermieness though, Reverse barely slowed the bananas down for a day. I purchased the seeds in 2008, hopefully they've gotten the sexual instability ironed out by now.
Try one plant at a time, if it hermies one plant isn't too bad to deal with. Get some Dutch Master Reverse and Penetrator when you order your feminized seeds. Always good to have around.
I've grown 6 of fem BF Blue cheese, not a single herm. Nice main cola with significant growth on the sides. Bud was awesome. I did hear that the red diesel was prone to hermies, but I haven't heard that about the LSD, which I plan on ordering the next time in addition to more of the Blue Cheese.
It's starts out a little heady, then it knocks you flat on your ass. It was better than I expected. I have some friends growing other strains, one WW and pineapple express. We all agree that the Blue Cheese is noticeably better. We all use the same brand of nutes and flower under 400w HPS, no CO2.
