The single greatest strain for straight up couch lock.... it's what it's bred for, it was the goal. Hard to get in the USA unless you want to pay $50 for shipping.
BIG BAZOOKA!!!!!!! (Not just bazooka, bazooka is a sativa leaning hybrid...) . It grows awesome, It's Big Bud x Jack Herer. I have not found it available stateside...IF ANYONE KNOWS PLEASE CONTACT ME!!!!!!!!! PLEASE PLEASE PLEASE. Sensible Seeds, Anesia Seeds carry it, but, 3 seeds, 50 bucks + 50 shipping. I've grown it once, only 1 of 3 germinated, so that was an expensive seed.
Anyone that's grown Big Bud will likely agree, it's a big ass plant. Jack Herer, I think it's crap, but used in many hybrids. Together it's a 30% THC plant with massive yields.
This is just my opinion please don't respond with some jackass response about how I'm wrong about something. It's my opinion.
