An Old-School Legend in Even Less Time!

Critical Mass Auto is an autoflowering cannabis strain brought to you by Big Buddha Seeds as a cross between the legendary Critical Mass and an in-house autoflower to yield one the best performing autoflowering cannabis strains on the market today – an all-round, well-performing Indica.

Like most autoflowers, Critical Mass Auto is sensitive to stress but she is forgiving to most beginner mistakes so if you’re new to growing, don’t be discouraged! More experienced growers will have no problems with this fast-growing Indica-dominant autoflower and can expect to pull 75 g per plant indoors and twice as much outdoors! This strain goes from seed to harvest in as little as 9 weeks – perfect for those looking for a quick harvest of potent, high-quality cannabis. Here is some further information to help you grow this strain:

  • Short plant – even though she is 40% Sativa, Critical Mass Auto stays short, bushy and below a metre in height.
  • Max EC of water – 1.0 in veg, up to 1.2 during flower.
  • Water pH; 5.8 – 6.0
  • Best grown using at least 600 W of LED/HPS lighting.
  • Ideal for SoG – sea of green style grows can boost yields.

Critical Mass Auto - Dense and Heavy Buds

This strain has a classic smell and taste – a pungent hash-like aroma which intensifies as her terpene profile complexes towards the end of flower. In addition to her nostalgic taste, Critical Mass Auto has a calm, relaxing effect which is best enjoyed in the evenings.
