the nirvana seed question usually generates a good number of answers
i just bought a couple of orders of nirvana seeds after a couple of months of reading various grow sites
not sprouted yet, just finished another grow from different breeder
my nirvana summary is you will get some good quality genetics at a good price
on the other hand, you may find quite a mix of plant types that pop out of those seeds, there will be good plants in there, but they may not be exactly what you were expecting
