Strain Overview

Origin

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.

Effects & flavours

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.

flavour-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.

THC & CBD Levels

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.

Terpenes

While the specific terpene breakdown isn’t listed, the flavour 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.

Growing Hellfire OG Auto Seeds

Grow Difficulty

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.

Indoor vs. Outdoor Growing

This strain’s compact height of 60 cm to 80 cm makes it ideal for stealthy indoor grows or tight greenhouse setups. Outdoors, she reaches roughly the same height, from 60 cm to 80 cm, 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.

Flowering Time & Yield

She flies through her life cycle, with a flowering period of just 55 to 65 days. Indoors, growers can expect between 300 grams per m2 and 400 grams per m2. Outdoors, she delivers between 80 grams per plant and 150 grams per plant, depending on conditions and care. Not bad at all for an autoflower with this kind of punch.
