yeah, i would also go with what whiter said.. thin, long leaves.. sativa or sativa dom, shorter, broad leafs, indica or indica dom strain... and the fact that you said that it is taking forever to mature would also make me think that it has alot of sativa in it as they tend to want to go much longer, some up to 14 weeks or so, as opposed to an indica dom strain that will finish much faster.. some as short as 7/8 weeks..
just tell your friend to keep an eye on the trics and when most of them start to look cloudy, or some cloudy, some amber, flush her out for a good week with plain phed water.
nice looking buds though.. hope she smokes as good as she looks
