I grew several times a cross between Nanda devi and a south indian pure sativa (>16weeks). Harvested mostly between 10 and 12 weeks. It’s still the best high I experienced: pure, clean, strong, creative, never racy, long lasting.
I also enjoyed a special cross given by a great friend which was built upon a special individual of Federation Hawaian which was really sativa and citrus / incense smell with a strong clear high. He backcrossed it two or three times and then crossed the resulting progeny with a Kumaoni male. And then, backcrossed some F1 female with a Kumaoni male again. He called it the Kumawaian lol Very funny happy stuff
I tried also a cross he made between Nanda devi and Santa Maria / Planck cut. Good production and short flowering with goofy high.
He told me some other tries were not as good, like Nanda devi x Hawaian or Nanda devi x Sweet Pink Grapefruit. The terpenes mix was not on par with the parents and the high was blur, he said.
I never tried Kashmiri strains but was curious about the Kashmir Resin Factory sold by Dr Greenthumb long time ago.
I was given fresh indoor seeds of the Nepalese Rolpa, that I plan to experience in a couple of months. Smelled it (but not smoked it ) , nice mix of berry , malt and spices, can’t wait to see if I get it in my room !
