Monster Yields, Sublime Sedating Highs, Luxurious Flavous - 45 to 50 Days!

Monster Mass is, in a word, amazing! Try as hard as you want, but we promise you will not be able to pick out the single best thing about this incredible feminized seed. The THC is fierce at 18 to 20%, the yields are unbelievably high at 800 g/rm2 inside or 900 gr/seed outside, and the finishes are shockingly early - beginning of September outside and as fast as 45 days inside. See what we mean?

  • Monster Mass Yields up to 800 gr/m2 Inside!
  • Finishes in a Very Fast 45 to 50 Days - Under 7 Weeks!
  • Hardy & Resilient with up to 20% THC
  • Critical Mass & Critical Plus Genetics!

As you go down the list, Monster Mass Cannabis Seeds just get better and better! Next up, the flavour & aroma. Both are sweet and fruity, but the sugary taste has subtle hints of blackberry, cola and kush while the fragrance has threads of Skunk and sweet Hash running through the stronger scents. The effects are simply spectacular with a long-lasting sedating effect that can keep going for upwards of 3.5 hours. Fantastic!

A Real Beast with Gargantuan Yields & a Fierce, Fruity Essence!

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!
