Huh, the Nirvana Mango knockoff is Papaya and yes, it is one of their better strains.

F= filial generation of a hybrid.
F1 is the first hybrid generation
F2 and beyond are interbreedings of the previous filial generation.
stinkyattic Reviewed by stinkyattic on . Nirvana Seeds vs. Originals? Hi- It took me a bit to figure out why Nirvana seeds are so cheap compared to everyone else, then I realized that it is "their version" and not the original seeds from the seedbank who developed it. White Widow from Nirvana vs. White Widow from Dutch Passion for instance. Does this make a difference? Is there a reason I should choose one over another? Thanks Rating: 5
