Monster Mass feminized seeds



Monster Mass: Head To Toe High

Like its name, Monster Mass produces a monster effect in its user, affecting both the mind and body by relaxing the muscles and stimulating the appetite. It’s also a strain that should be approached with caution, especially by new users, as it has a high 20% THC.

A Canna Monster With A Rich Fruity Flavor & Skunky Aroma

Monster Mass offers a sweet, sugary and fruity flavor with a blend of citrus. These are combined with other underlying flavors such as blackberry, cola cubes and kush to give it that sweet, fruity flavor when inhaled. The strain is popular for its intensely pungent and skunky aroma, giving the user a powerful and overwhelming scent. This aroma, combined with the fruity taste in the mouth, make this cannabis strain highly enjoyable.

Monster Mass: Ideal For Indoor & Outdoor Growth

Due to the strain’s quick flowering and hardiness, it’s ideal for both indoor and outdoor growth. It takes 45-50 days to grow indoors, while outdoor harvest time is in mid to end-September.

  • Outdoor growth is recommended due to height
  • LST isn’t necessary for outdoor growth but is necessary for indoor cultivation
  • When growing indoors, FIM at an early stage to boost production

Famous Critical Genetics

Monster Mass is made from a combination of Critical cannabis and Critical Mass strains. It was developed by Critical Mass Collective, and the breeders have acknowledged that this cannabis strain is the reason for their insatiable thirst to cultivate the best Mass hybrid in the world.
