Germinated inside in a incubator with natural light under a window. Not a great germination rate, about 50%. I noticed that the seeds package harvest date was over 2 years old, maybe something to do with it. Seeds were also quite small. Out of 14 seeds I ended up with 4 viable (2 Black Jack Auto and 2 Red Poison Auto), 8 failed to germinate either at all or past the taproot phase, 2 seeds leftover.
Outdoor grow, harvest at 9+ weeks. Had quite a lot of cloudy/rainy days so that didn't help size. It's for myself so it is what it is. My first autos outdoors, would do it again because it's so easy.
