Nanda Devi was surprisingly potent and has the best quality high out of any of the RSC himalayan landraces I've tried. Flavorwise, it's nothing to write home about, but decently tasty. Not the easiest to get rosin from, but that might vary from one plant to another.
Keep in mind, nanda devi was also selected for hemp, so even if you start them somewhat late outdoors, expect them to reach several meters in height...the internodes are very long. 3/12 germinated (compared to 100% germination from Kumaoni), this was from fresh seeds too, but getting this one female in the end made the acquisition worth while. I think this strain is definitely worth looking in to, but grown outside of it's place of origin, expect high rates of somewhat controllable hermis (the two males were also hermis, but male dominant):
Manipuri, on the other hand, didn't show any signs of hermi problems, and the potency, flavor, and high are all top notch. For me, it finished between end of December and Early January outdoors in the Pacific NW.
