Blue Mammoth Auto: Straight Out of Barney’s Farm

Blue Mammoth Auto is an autoflowering cannabis strain created by Barneys Farm. One of their most popular autoflowers, Blue Mammoth Auto came about as a cross between two legendary genetic lineages – Skunk and Lowryder #1 – to yield a wonderful hybrid which delivers excellent results in lightning-fast times.

World Famous Autoflower With Heavy Yields

Like most Indica-dominant hybrids, Blue Mammoth Auto grows with a very typical structure – a main cola with several side branches which grow slightly smaller but still impressive buds. Those who are fans of resin-heavy flowers will enjoy Blue Mammoth Auto as her mainly-Indica genetic lineage makes her very greasy – perfect for cannabis concentrates! Indoor yields for this strain are 600 – 700 g/m2 when grown via SOG (sea of green) using at least 600 W of high-power LED lighting. Going from seed to harvest in 10 – 11 weeks, Blue Mammoth Auto is a fantastic strain from beginner growers due to her ease of handling and lack of issues. Here is some further information to help you grow this strain:

  • Medium height – Blue Mammoth Auto reaches a final height of 1.2 – 1.4 m.
  • Max EC of water – 1.1 in veg, up to 1.5 in flower.
  • Water pH; 5.8 – 6.0
  • Recommended lighting: Veg: 300 W CMH, Flower: 750 W LED.
  • Recommended nutrients: Advanced Nutrients pH Perfect® Connoisseur Bloom Part A&B.

A Greasy Indica-dominant Autoflower

Blue Mammoth Auto is known for two things: amazing blueberry flavor and dense flowers covered in a pungent resin, which makes excellent concentrates. Her effects initially make you talkative and is uplifting but slowly fades into deep body relaxation which soothes the mind and body simultaneously.
