I think there the best for the price...I have a script ,so I have access to all strains at the Co-Op.He used Sagarmatha Yumbolt in some of his strains.
See he crosses the best of the best and soon he's going to have some straight
Bubba kush
G-13
Stuff like that...
Right know those are only available in crosses.
I'm about to pop some of these...
Kranial Kush=(OG Kushx Bubba Kush) x (Bubba kush x Yumbolt)
Oguana Kush= OG kush x Herijuana
Dirty Harry=(Bilbo's)Grapefruit x Herijuana
Killian=Killa Queen x NYCDiesel ...(Killa Queen=G13 x Cindy99)
Gbolt=G-13 x Yumbolt

That link is to a European site but just google Motarebel if you want to find an american site where you can get his Strains.
