Nirvanas seeds are good in my eyes but alot say that they got shitty genetics n got shipping problems. I'd go through a major seedbank to get their seeds bra.
Oh n they are reliable to me but got problems right now from all this i aint get my seeds shit etc.
Force gemin? Never heard of it.
U may be talkin about using da paper towel method bra.
Nirvana is a nice cheap site to get seeds from for a few grows, I would switch to some higher end genetics once I got my shit down though. Not that nirvanas are bad, there are just better.
