I have had very good luck with the single seed centre and will use them again and again.
As far as the auto's are concerned I grew a few of Stitch's strains last year and will never grow them again. I tried the Blue Himalayan, the Russian Rocket, and the Onyx. I ended up giving them all away in their pots before they finished. I was a member on another forum for just auto's that Stitch frequented. There were so many write ups about how great these strains were. I thought they sounded like great so I bit.
There were no major problems. They just have a mind of their own and do not like being told anything different. I like to impose my will on plants. I love topping, super cropping, and LST and have had luck with doing this with autos in the past. NYCD was an auto that I could do anything with. I even wrote Stitch to find out if it was just me but he never replied so I said screw it.
I came to the conclusion that after 5 weeks and absolutely no crystals that these were not the strains for me. I tried a few more auto's after Short Stuff and found Females AK and auto bubble to be much much much better than the Short Stuff gear. This was my slap in the face and realization that I shouldn't believe companies or breeders own write-ups.
One auto bubble yielded over 120g's. I think it was an accidental super auto but still it was an auto and blew minds. I am pretty sure I have pics of it in my journal.
As far as breeding goes. I am not one but I do dabble in it and have always been told never to use fem seeds for breeding. Different strokes for different folks though so I am sure someone will say otherwise.
