These Killers are Set to Auto Pilot - We Kid You Not!

Once Auto Massassin Seeds are set in motion, there's no stopping these serial killers! They'll slay you with their immense yields, awe-inspiring power and full-throttle speed on the very first go. No matter what, 55 days from seed is all they'll need on average. That, my friend, is only 2 measly months, 8 short weeks or 1320 brief hours. You'd have to break the laws of time to get anything faster!

  • Includes Genuine AK-47 Genetics!
  • Finishes in 55 Days from the Very Start
  • Very Smooth & Pleasant Flavour - Like Lemon Candy
  • Plenty of Resin, Terpenes & Bag Appeal!

To achieve this miraculous feat of genetic engineering (that's breeding to you & me), Critical Mass Collective crossed their very own Monster Mass and Big Bud Auto with the original one-hit wonder, AK-47. As a result, the Auto Massassin strain comes on fast and lasts for hours, lifting the spirits first for a quick rocket ride before settling down into a mellow buzz that completely saturates both the mind and the body. Perfect!

To create Auto Massassin Cannabis Seeds, Critical Mass Collective reached deep into their vault of breeding stock and pulled out an original AK-47 to pair with their signature Monster Mass and unreleased Big Bud Auto. Combined, this mix is a real powerhouse with freaky-fast 55-day finishes. Blink and you could miss it! By the end, these weed seeds are capable of reaching up to 450 gr/m2 inside with a whopping 20% THC rating. How can you possibly take a pass on this CMC exclusive?

Review this product
Before the Critical Mass Collective was even a gleam in Critical Lee's eye, this highly respected breeder fell in love with the legendary Critical Mass strain. Of course, he couldn't pass on the chance to improve on perfection, so he soon tweaked CM until he came up with Monster Mass, a new hybrid with even more yield & more power than it's infamous mom. Today, you can take advantage of all that hard work and pick up your own Critical Mass Collective feminized and AutoFem seeds. You'd be crazy not to!
