I am very pleased with Nirvana. Planted two B52 beans, both were severely neglected, as I too thought they were of poor stock. Both showed female pre flowers at 28 days and were sent to flower. With minimal effort these plants exploded. Each 2 foot plant yeilded 3 oz each, outpacing a few more expensive seeds, and i trimmed a good part of the bottoms off for clones. The taste and smell are incredible, like nothing I have ever had. B52 from Nirvana is excellent.
