The 5 Strongest Autoflower Strains

  • 1. Gorilla glue
  • 2. Girl scout cookies
  • 3. Six-shooter
  • 4. West coast og
  • 5. Tangie'matic


Everyone wants to grow strong weed, and the first step to that end is picking the right strain. Modern autoflowering strains, like those from Fast Buds, can be just as potent as their photoperiod cousins. With THC levels reaching 24%, autoflowers have truly come into their own.


However, potency is not the same thing as having a lot of THC. Yes, it's true that the strongest strains are high in THC, but THC alone doesn't do much. Ask anyone who has taken pure THC or smoked THCA crystals. Yeah, it gives you one hell of a buzz, but it lacks the magic that stoners are looking for. Other cannabinoids like THCV and CBD, along with flavonoids and terpenes, augment the effects of THC, almost always for the better.


Below we run down the five strongest autoflower strains from Fast Buds. They sport high levels of THC, but it's the other chemicals found within that make for an amazing buzz.

A worldwide sensation, Gorilla Glue has obtained near-mythic status for cannabis aficionados. Fast Buds autoflowering version hits 24% THC and produces a relaxed, happy, and euphoric high. When grown properly, Gorilla Glue produces rock-hard resinous buds with a hell of a kick. This ideal sativa-indica blend is perfect for wowing your friends at a party.

2. Girl Scout Cookies

I grew my Girl Scout plant outdoors and the weather was mostly cloudy in flower with frequent rains. There were no issues with mold though.

Another world-wide phenomenon, Girl Scout Cookies set the US west coast cannabis seen ablaze, and Fast Buds was thrilled to roll out our autoflowering version. While GSC reaches levels of 22% THC, the secret to its magic is another cannabinoid THCV. Made famous by GSC direct ancestor, Durban Poison, THCV is a potent stimulant cannabinoid that paradoxically reduces THC induced anxiety. Girl Scout Cookies isn't just another high-THC hybrid, the THCV keeps the paranoia at bay, allowing everyone to get ripped without worrying about a freakout.

3. Six-Shooter

You don't need lab equipment to see that Six-Shooter is a potent strain. Its buds produce a sticky, white resin that practically screams, "smoke me!" This cross between our Mexican Airlines and Crystal Meth strains reaches a THC content of 21%, and if that wasn't enough, it's one of our highest yielders. Our resident master grower, Hawkbo took 352 dry grams (11.5 ounces) from his. Six-Shooter's combo of quantity and quality is second to none.

4. West Coast OG

Ahh, the classics. OG Kush is a legend for a reason, and Fast Buds' autoflowering version, West Coast OG, packs the same punch as the original. 21% THC and it smokes and feels just like its legendary namesake. What more do we need to say?

5. Tangie'Matic

If you like to smoke to get on and do stuff, this is a good choice. If you want weed to sleep, I wouldn't recommend this one.

Tangie'Matic is Fast Buds' giant citrus wonder. Reaching 1.3-meters in height (massive for an autoflower). Fast Buds autoflower Tangie features 21% THC and an unforgettable citrus odor. It may not be obvious, but it's that odor that's the secret to Tangie's potency. Citrus smells in cannabis come from limonene, a chemical also found in oranges. High limonene strains tend to be energetic sativas reported to have both anti-depressant and anti-anxiety effects. The medical applications of this terpene are still being studied, and it may one day turn out to be the chemical that gives medical marijuana some of its efficacy. But until the data comes in, all you need to know is that this pungent terpene gives Tangie'Matic an energetic high that can't be replicated.
