Looking for an auto that doesn’t mess around? Hellfire OG Auto is a fast and fiery indica that slaps hard, tastes like lemon zest, and keeps your brain buzzing while your body chills.
Hellfire OG Auto doesn’t just enter the room quietly. It kicks the door open, sparks up, and lets you know it’s not here to mess around. This autoflowering version of the legendary Hellfire OG stays true to its name. It’s hot, potent, and hits with the precision of a well-rolled uppercut.
This isn’t your mellow evening companion. Hellfire OG Auto is the kind of strain you reach for when you want to light a fire under your creativity or power through a social hangout with a big goofy grin. And with its compact structure, quick turnaround, and brutal 29% THC potential, it brings some serious weight in a surprisingly easy-to-grow package.
After bigger yields and a little more control over training and timing? Our Hellfire OG photoperiod version gives you room to dial everything in.
Hellfire OG Auto is the lovechild of Hellfire OG and a sturdy Ruderalis, combining raw potency with autoflower convenience. The original Hellfire OG itself descends from OG Kush and SFV OG Kush, which gives this strain a rich, Californian backbone soaked in diesel, citrus, and pine. Now, with the autoflower genes in the mix, all that West Coast firepower comes in a quick, manageable format ideal for even first-timers.
Expect a rollercoaster. The high starts off bright and euphoric, dialing up the energy and flipping the creative switch. As it settles in, it smooths out into a relaxed, happy state that doesn't glue you to the couch but keeps your limbs nice and loose. It’s equal parts head buzz and body chill, making it perfect for socializing or riding a wave of focused inspiration.
Flavor-wise, this one’s a wild ride. Citrus and sour lemon hit first, followed by a blast of pine, diesel, and earthy spice. There’s even a peppery edge that lingers on the exhale, giving the whole experience a sharp little kick.
Hellfire OG Auto is not playing around with potency. At 29% THC, it easily competes with the strongest autos out there. The CBD content is low, around 0.5%, so the effects lean heavily into the psychoactive and recreational side. Definitely a strain to approach with respect.
While the specific terpene breakdown isn’t listed, the flavor and effects suggest a combo of limonene (citrus zing), pinene (pine and clarity), and caryophyllene (peppery edge and a bit of muscle relief). That mix delivers not just a punchy high, but a full-sensory experience from spark to fade.
Beginner-friendly and fast, Hellfire OG Auto is a fantastic pick for growers who want high returns without jumping through too many hoops. She’s robust, forgiving, and resistant to fungal issues. Perfect for anyone just starting out or anyone looking for a hassle-free harvest with heavyweight results.
This strain’s compact height of 24 inch to 31 inch makes it ideal for stealthy indoor grows or tight greenhouse setups. Outdoors, she reaches roughly the same height, from 24 inch to 31 inch, and thrives in cooler regions like mountainous or temperate climates. She can even handle short summers. Whether tucked inside a grow tent or planted discreetly in the garden, she doesn’t demand much but gives back plenty.
She flies through her life cycle, with a flowering period of just 55 to 65 days. Indoors, growers can expect between 1 oz per square feet and 1.3 oz per square feet. Outdoors, she delivers between 2.8 oz per plant and 5.3 oz per plant, depending on conditions and care. Not bad at all for an autoflower with this kind of punch.
Looking for a fast, fierce, and flavorful autoflower that’ll light up your grow space and your stash jar? Hellfire OG Auto is it. With sky-high THC, mouth-watering flavors, and easygoing cultivation, this is one hell of a ride for any grower ready to turn up the heat.
