determing strain?

I was wondering if there is any way to tell what strain a plant is, seeds were taken from bagseed. Males were removed. I have no clue what strain or type. 2 plants look very diffrent about 2-3 weeks from harvest, one looks short (about 50") with full, thick, heavy kinda white looking buds and lots of crystals. The other is very tall (about 72") with long slender more greenish and furry looking, and not quite as crystally looking but that {the having fewer crystals} may be due to about a week less time under flower lights so far.
it would be nice to know type but atleast weather indica or sativa at least.

sorry no pix at this time is there maybe a website or something I can compair pictures?
TIA!!

there is a hundred strains and more crosses you could maybey get close,but it would be hard to pinpoint unless some one in your home town has seen the bud before.hope you figure it out.
