I know this is an old post but here gos....
Im just starting my third grow, used sensi seed skunk number one both times, was very impressed.they can take a lot of abuse ( unintentional) and were big heavy hitters for me !
I decided to try sensi seeds northern lights and nirvana ice for this run, as is heard a lot of good things about both strains.
I put 1 NL seed and 2 nirvana ice seeds into germinate, the NL worked sweet but both the nirvana ice died, they just wouldn't take.
So I put the other 3 ice in, using the same germination techniques as I always use and guess what ?
They didn't make it either.
Maybe it's my germination method , I dunno, but I've never had problems with sensi seeds.
First and last time I'll purchase from Nirvana.
Just my opinion anyway
