There are at least 3 Think Different grows on here. People are getting consistent high yields, but many of them go for 90 to 100 days because they veg a little longer than other autos, and some phenotypes flower for longer than others. Search "Think Different AFN" in google and you'll find a bunch of people growing them on here.
Not too sure about the others except that auto snow ryder and easy ryder are probably ripoffs. The original easy ryder comes from the Joint Doctor, and Snow Ryder comes from Short Stuff seeds. Sounds like flowering seeds blatantly ripped them off, and didn't even bother to call them something different to cover their tracks.
