Growing Hellfire OG autoflowering seeds (indoors and outdoors)

Being an autoflowering variety, Hellfire OG auto seeds can be grown in any indoor, outdoor, or greenhouse setup. The sturdy ruderalis genes will ensure prosperous growth regardless of any light cycle or environmental circumstances. That said, a warm climate, using organic soil, and applying a Sea of Green training method will always benefit the final yield.

Due to her 70% Indica genetics, Hellfire OG auto has a short, bushy growth, with sturdy branches and stunning minty green leaves. As harvest time approaches the resinous buds will glisten pearly white in the evening sun as you rejoice in the anticipation of all that goodness to come!

Like all our autoflowering varieties, Hellfire OG auto marijuana seeds are feminized by default so you don't have to worry about unwanted males! Perfect if you want to ensure a harvest of your own homegrown cannabis.

Flowering time

Autoflowering Hellfire OG cannabis seeds grow into sturdy plants with a short flowering time of about 55 to 65 days. While that may not seem overly fast, the biggest time gain is in the extremely short vegetative phase.

Due to this much shorter grow circle, it is possible to realize multiple harvests outdoors, before the season is over. In the Northern Hemisphere this means that you can harvest both early July and mid-October.

Plant height

Due to the addition of ruderalis genes, auto Hellfire OG marijuana plants remain short and manageable, with an average height between 80 and 100 cm, both indoors and outdoors. This makes this autoflower strain very suitable for those with small grow spaces.

Hellfire OG strain yield

The modest stature of Hellfire OG auto-fem cannabis seeds is in no way reflected in the yield. Due to the abundant resinous nuggets, these dense buds still put a very nice weight on the scales.

Indoors, under ideal conditions, the average yield will be about 300-400 grams per m².

If you grow your Hellfire plant outdoors, yields fluctuate between 80 and 150 grams per plant.

Effects of Hellfire OG autoflower

Despite being a predominantly Indica variety, Hellfire OG auto marijuana offers nicely balanced effects that work wonders on both the body and mind.

Before the sedating body buzz sets in, the user experiences a powerful sensation of euphoria which instantly brightens the mood.

As the body stone creeps in, you'll notice your muscles loosen and stress starts to subside. The wonderfully relaxing sensation this brings about can help alleviate painful conditions such as chronic pain, sore joints, and cramps.

Medicinally speaking, her potent anti-inflammatory properties make her a popular choice for all kinds of physical discomforts. She can also aid in reducing mental issues like depression, stress, and even bipolar disorder.

Side effects

The danger of overdoing it is that it can lead to paranoia and anxiety. However, when used in moderation, weed grown from Hellfire OG seeds has surprisingly few adverse effects, despite her high THC content.

The only notable side effects are dry mouth and eyes, easily remedied by maintaining hydrated at all times during and after use.

Smell and taste

Alluring aromas of herbs, pine, and pepper emanate from Hellfire OG's buds.

An exotic Thai incense aroma can be detected along with notes of lemon citrus and dank earth.

The flavors of lemon, pine, peppery, spicy fuel, and just a hint of kush, perfectly complement each other in this wonderful blend of fragrances.


The legendary heritage of Hellfire OG auto-fem cannabis seeds was forged by crossing two celebrated varieties, OG Kush and SFV OG Kush back in the 1960s.

It is OG Kush that contributed the strong cerebral and physical effects to her offspring. SFV OG Kush passed down her robust plant structure, earthy flavors, and delicious aroma to the feminized Hellfire OG auto seeds.

Adding potent Ruderalis genes into the mix resulted in highly potent and fast-growing cannabis seeds that rapidly became a top medicinal marijuana choice.
