Magnum Autoflower Profile by Kyle Kushman

Some people have a hard time starting a conversation in a social gathering, but all that changes thanks to Magnum’s chatty, long-lasting high. Now, instead of visiting dispensaries, introverts can grow their own crop with these feminized autoflowering seeds from Homegrown Cannabis Co.

The plant’s precise genetics are shrouded in mystery, but not because the information has vanished into obscurity. Instead, the original breeder chose to keep it secret. Some people suspect that one of its parents could be Jack Herer or Haze. Regardless, it is a three-way split of Sativa, Indica, and Ruderalis.

The plant’s name is reminiscent of the mighty Magnum 44 carried by Dirty Harry. In more ways than one, it’s an apt comparison because this is surely one of the most potent autos in the world. Rather than blitzing in at the onset, it’s unique in that its cerebral effects build up gradually over time before settling into a relaxing and tranquil state of bliss.

Growing Magnum from Autoflowering Seeds

Some people take issue with autoflowering strains, saying that the buds lack flavor and potency. While this may have been true in times gone by, it is much less of a concern nowadays. In fact, many people agree that Magnum is the most productive and potent of all autos on the market.

Cultivating the strain is pretty easy, for two reasons. First, it’s naturally resistant to pests and fungus. Second, the seeds are feminized so there is hardly any chance of producing male plants. Even when subjected to minor levels of stress, these ladies do not have hermaphroditic tendencies.

For the most part, growing it indoors only requires a 20/4 light cycle, but be aware that the plants can grow up to 5 feet tall so you’ll need large pots. After a flowering period of 10 to 12 weeks under 600W lamps, each square foot can produce as much as 1.63 ounces of nugs.

In the great outdoors, the plant goes from seeds to bud in around 75 to 90 days. At harvest time, each plant can produce around 7 ounces.

Fragrance and Flavor

Magnum emits a fresh and pungent scent. It has a spicy flavor with a hint of sweet citrusy notes to balance it out.


Magnum is a pretty potent strain that has a decent THC level hovering around 12-15%. Its slow-building buzz intensifies over time and this is one of its most unique and sought-after qualities. As soon as the euphoric high settles in, not only does it leave users feeling uplifted, but they are also much more sociable. When enjoyed in a friendly group setting, you can expect non-stop talking and a lot of giggling. For this reason, it’s an ideal strain for introverts who need a little something to help bring them out of their shell.

Similar to Haze, Magnum can reinvigorate users who are feeling tired and sluggish. The clear-headed high it induces is coupled with a boost in energy that allows you to stay productive. For artists, the heightened level of creativity is welcomed with open arms.

In time, Magnum’s physical effects will creep into the body, blending seamlessly with the cerebral high and making laziness unlikely. Instead, it’ll keep you feeling calm and relaxed without going overboard on the cerebral high.


The recreational effects of Magnum may also be beneficial to medical users. In particular, the mood-enhancing abilities of this strain may help melt away stress and depression – although temporary, the euphoric buzz can provide a welcome respite.

To a certain extent, Magnum may also provide pain relief. Some people have used it to alleviate migraines, eye pressure and other discomforts.

Despite all of its potential medical benefits, smoking Magnum can still cause some adverse effects. Cottonmouth and dry eyes are some of the more common reactions that users might experience, and it may also cause some to feel slightly dizzy.

Because Magnum is a predominantly Sativa strain, and a potent one at that, beginners should be wary when smoking it. Excessive consumption may cause feelings of mild anxiety and paranoia, and this can usually be avoided by decreasing the dosage.

Autoflowering Magnum Seeds

With its slow-building buzz and its spicy, citrusy flavor, Magnum can bring joy to both recreational and medical users. Even breeders find it a joy to grow because of its natural resilience and high yield. With these autoflowering seeds from Homegrown Cannabis Co., it can be planted at any time of the year. There’s no reason to ever be without this amazingly potent strain.
