I have grown G13's PE photo and it was suuuuper dank. Definitely a good mix of indica/sativa. Narrow, long bud leaves - not kushy at all. And compared to most 8 week strain's it's pretty uppy and doesn't burn you out too bad. Mine had a sweet onion smell freshly cut, but matured to a smell like over-ripe citrus fruits. Maybe there are some pineapple phenos out there, but I just had the one freebie to grow out.
I have heard of some roots of C99 in there somewhere.
