Hindu Kush for sure. Deep Deep green, and skunky as fuck. One bowlfull fuckin had me floored. I dont know the lineage of the nuggets, but It fuckin Killed me. Ive also had some Northern Lights that were awesome, but it felt more like an up n active high rather than a "put me on my ass" stoney high.
I prefer the Sativa type active high though personally. Save the Indicas for bedtime, lol. Plus Sativas are the strains where you get your fruity taste and smell from. Thats how you get a fruity indica, by crossing it with a Sativa - as far as i know, there are no really fruity standalone 100% indica plants. correct me if im wrong though
