if the bud in the bag was fluffy..your seed is likly sativa..11-15 weeks flower..if the buds were dence indica..8-10 weeks flowering..there realy isnt a way to know for sure though
Even with out seeing the bud in the bag seed you should know if it's indica or sativa dominant by how tall it gets and how fast it gets that all. Indica's are gonna stay smaller than sativa's unless you let them stretch like crazy by not having enough light. Still, you don't know what the flowering time is going to be, just a reference of what the usual is.
Edit: fluffy bud can be caused by more than just genetics. Heat, light, stress, nutrients and how long you let it flower can all effect how dense your bud gets
