Thunder Bloody Mary Auto Strain Info

Thunder Bloody Mary Auto is a feminized cannabis variety by Samsara Seeds’ breeders. It was created as a cross between two famous strains to birth an Indica-dominant autoflowering offspring with excellent yields and fantastic resin production.


This potent strain is a cross between the famous White Dwarf and the classic Mazar, holding unique properties courtesy of the strong landrace genetics from its Mazar lineage.

Flowering Time

Part of this strain's claim to fame is its super-fast flowering time of as few as 60 days from seed.


In such a short time, this strain delivers impressive harvests of up to 400g/m2 (1.3oz/ft2) indoors and up to 70g (2.4oz) per plant in an outdoor grow operation.


When you think of a Bloody Mary, do you get flashbacks of a drunk blackout? Well, throw “thunder” into the mix and you’re onto something! This strain has the most potent knockout narcotic effects that aren’t for the faint of heart.

The best part is that you get all the fun without the nasty hangover – although maybe just a little bit of couchlock to keep you from going anywhere.

THC Levels

Thunder Bloody Mary Auto’s effects are all but unheard of for her THC content of 21%. If you’ve had other strains this potent, don’t let your guard down just yet!

Smell and Taste

This potent cannabis strain will knock you back in time with an old-school marijuana smell you don’t often find anymore. Complemented with hints of musk and accentuated by notes of pine and wood, try not to think of high school when you smoke this nostalgic strain.

Grow Tips

Her buds are chunky and covered in resin and trichomes, which make for excellent finger hash when trimming. Thunder Bloody Mary Auto presents very little difficulty in growing thanks to her strong parentage.

White Dwarf is already highly regarded within the autoflowering community, but crossing it with a pure Mazar has raised the bar on how well an autoflower can perform in such a short growing cycle. TBMA’s excellent resistance to mold and pests combined with her Indica lineage makes this plant suitable for growing outdoors. Help your plants thrive by implementing the following grow info:

  • Use at least 600 W of HPS or full-spectrum LED lighting when growing indoors to maximize yields.
  • We recommend a light schedule of 20/4 to give your plants all the light they need.
  • SoG arrangements work well for this strain.

    • Disadvantages
    • General impressions
      Very easy plant to grow. Just let her sprout and grow for the first month. Then start with flower nutrients and continue to harvest. Very tolerant of environmental conditions, and over feeding. Nice yield, and great high. I've grown this strain three times in the past two years... highly recommend for any level grower, but beginners will love it.

    • Advantages
    • Disadvantages
    • General impressions
      Soil/hydro: Soil fox farms ocean Forrest
      Nutes: Grow big and tiger bloom
      Light (kind and schedule): 400 hps 24 hours straight through
      From seed to harvest date: 59 days took about a week early.
      High/Effect Duration (how long did effects last): not the longest lasting high maybe an hour or so.
      A good strain to grow it was fast pretty low odor so if stealth is an issue good strain for that. Pretty forgiving as well developed an mg deficiency and still yielded pretty well not the most potent smoke but does the job.
      THE GROWth: Fast growing really took of at around two weeks final height was 17 inches.
      THE SMELL: Not the best smelling stuff been curing for going on two weeks and it's just not that strong same with the taste.
      THE SMOKE: A little harsh on the exhale but over all a decent smoke not the best I ever had but not the worst either.
      THE HiGH: it is a creeper at first kind of a head rush then sinks in to a couchlock this is some super munchie weed I have been eating to many cookies and sweets since I have been smoking this.

    • Advantages
      Made me happy, relaxed and sleepy 😊
    • Disadvantages
      Can cause dry mouth
    • General impressions
      Easy to grow strain. Great for an autoflower. mellow buzz, but long lasting. Good strain overall, definitely more for night time smoke and relaxing. I wish I would have used a bigger pot then a 1 gallon. Maybe I could’ve have harvested a bit more weight and had a little bit bigger plant. Overall a good strain, I got enough to smoke till I cut down my non-auto strains. First ever harvest for an auto or any strain.👍
