Lucky me!?

I don't think its going to be a F1 Auto. you looking at a photoperiod with an increased risk to hermi as that what its parents did. Automatic flowering traits are recessive. Meaning if there is one dominate trait between the two chromosomes in the seed embryo it will loose. If your auto was pollinated with a Photoperiod Runtz plant it would create "quick" seeds. they are 50% auto and 50% photo, they tend to finish a week or two earlier but they are still photoperiod not autoflowering in terms of light cycles. If the Runtz plant it was pollinated with was a quick version "50/50 auto/photo genetics", then it would have the following chances: 25% chance of being a fully automatic autoflower. 25% of being a pure photoperiod. 50% chance of being a quick version photoperiod. O FYI, there is the off chance the hermi autoflower pollinated its self. and that would be a 100% autoflower. But your question said it was a mix of the two so I went off of that. If it is an F1 auto it will show flowering traits by week 4/5 but I don't like to grow hermi seeds out. they tend to keep going hermi and mess up your grows. Hope this helps Happy growing
