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 up to almost 30%, 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. This is known as the entourage effect.

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.

1. Gorilla Glue Auto

A worldwide sensation, Gorilla Glue Auto has obtained a near-mythic status for cannabis aficionados. Fast Buds autoflowering version hits 24% THC and produces a relaxed, happy, and euphoric high.

2. Girl Scout Cookies Auto

Another worldwide phenomenon, Girl Scout Cookies set the US west coast cannabis seen ablaze, and Fast Buds was thrilled to roll out our autoflowering version, aka Girl Scout Cookies Auto. While GSC Auto reaches levels of 20% 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 Auto 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. Strawberry Gorilla Auto

You don't need lab equipment or lab test to see that Strawberry Gorilla Auto is a potent strain. Its buds produce a sticky, white resin that practically screams, "smoke me!" This cross between two of our most potent and flavorful strains, Strawberry Banana and Gorilla Glue, reaches a THC content of 28.4%, and if that wasn't enough, it's one of our highest yielders.

So expect jaw-dropping yields reaching 600 g/m2 indoors and up to 300 g/plant outdoors, on top of that, its extremely resilient genetics and easiness to grow make it the ideal, if not perfect, choice for beginners looking to get good results without any extra maintenance.

5. Gorilla Zkittlez Auto

Gorilla Zkittlez Auto is Fast Buds' giant citrus wonder. Reaching 1.5-meters in height (massive for an autoflower). Fast Buds autoflower Gorilla Zkittlez features 27.6% THC and an unforgettable fruity and spicy odor. It may not be obvious, but it's that odor that's the secret to this hard-hitting 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 Gorilla Zkittlez Auto an energetic high and an award-winning terpene profile that can't be replicated.
