Ha! I don't know what you've grown, but I've grown over 50 strains, and most were very good to kickass. Go to autoflowerportal.net and get some Stone Dragon, or NW's Sour Dragon. Or learn how to choose a strain.........
I'm growing my own strain I call Blue Dragon. Its a cross of Blueberry Headband and Durrty Dragon, and its kickass.
And Maybe you need to learn how to grow. Autos are no more mold or disease prone than any other cannabis. Many photo strains have that issue and its really mostly a lack of control of your environment. If your going to make statements like this, you'd best be able to back them up!
