MK-Ultra REG


MK-Ultra was named for one of the most infamous CIA-sponsored mind-control experiments that's ever been leaked to the public, but it's also based on G-13. Gossip has it that G-13 escaped from a top-secret US government lab as well. Here's to the Feds - in this case, they really know their weed seeds!
  • Regular Cannabis Seeds
  • Near-Addictive Power
  • Trippy & Psychedelic
  • Fresh Pine Flavour

Hypnotic, Trippy & Nearly Addictive!


With that list of talents, it's hard to believe MK-Ultra Seeds are mostly Indica, but, according to elite Dutch breeder TH Seeds, that's what they are. This is a premium mix of the super-classified G13 & the legendary OG Kush.

Don't underestimate the MK-Ultra strain. These weed seeds are packed with nearly addictive psychedelic power that'll make you want more & more. Good thing these trippy little killers are capable of pumping out up to 350 gr/m2 - that's not the biggest yield in the TH Seeds lineup, but it's nothing to sneeze at, especially when you're talking high-grade shit like this.
