My Grand daddy Purple is a pure indica, however the leaf structure is very sativa.

White Widow is a sativa dom (60-70%), however my seed grown girl has fairly fat leaves very similar to my Blueberry (indica dom 80%)

Is there a way to tell how long the flower will be on bag seed? No, not really.

Even tho I keep my room clean and free of males and hermies, I do have a male in flower in a separate area. A single grain of pollen on my shirt from that WW male could get on my Vanniluna Female and create a cross that might exhibit completely different growth/flowering characteristics.


Point is, if you don't know the strain the seed came from, and don't know the source of the pollen, you cant really judge flowering time based on the shape of the leaves.
