I can only speak of my experience with Nirvana.First off , let me say this: just because you buy seeds labeled Nirvana ,doesn't mean that you are buying "from" Nirvana.Rhinoseeds.com I will never buy from Rhinoseeds again.They buy and resell different seedbanks seeds.If you buy from nirvana-shop.com and have a problem , I assure you that I have never had a problem that they didn't promptly solve.
