What are the stonger seed strains that are available?

I was looking at Reserva Privada's OG Kush #18 fem seeds, since i noticed they seem to be in stock again. I thought that was a clone only strain... so that left me wondering.

What are some of the better known seed strains that you've grown?

White widdow
Kali Mist
AK-47
SLH



...?

I grew Nirvana's AK48. That shiite was STRONG. Edibles off the trim were off the charts.

bubba kush, og kush, sour diesel, chemdog, mass. super skunk, pine tar kush {if you can find any beans} are all in a leage of there own

yea, but what breeders for those seeds ;p
