newbie section is over here...

What strain? What subspecies? what sex? what do you mean?

you will never KNOW the strain, unless you back trace the weed (wich i doubt you can/will do) you can find out it is a sativa or inica dominant tho. sativas are taller and narrows, where indicas are lower and wider.
