i have grown White Rhino, White Widow, Northern Lights, Aurora Indica, Papaya and Bubblegum over the last 6 years. NL, WR, AI, Bub, were killer. The papaya was faily good, i did not like the Widow however she was leafy as hell, extremely long and sensitive stems that were weak and very delicate. People get pissed when I say it but the keepers i found in WR, NL, and AI I would put up against any top breeders plants. I've grown MNS, Serious, etc. and the keepers i found from Nirvana go toe to toe with the expensive seeds
